Six Flags Discovery Kingdom in Vallejo, California is a large sea mammal amusement park operated by the Six Flags group. The roots of the park can be traced back to another location in Redwood, California where it operated as Marine World from 1972 to 1985. The location in Vallejo then opened in 1986 to the public. In 1999, the park was sold to Premier Parks and the name changed to Six Flags Marine World. Nowadays, the park is known as Six Flags Discovery Kingdom and featured a solid collection of rides and attractions.

An evening at Six Flags Discovery Kingdom

Six Flags Discovery Kingdom

Six Flags Discovery Kingdom has one of the most impressive skylines of any theme park – at least the views from the parking lot are stunning. The theme park however has a very odd layup with the entrance area being placed somewhat in the middle of the park, splitting the park into two major ride areas to the left and right of the entrance and the zoo exhibits directly Infront.

Batman The Ride

My first ride of the day was the S&S Free Spin Coaster Batman – The Ride. As always, the ride comfort on this type of coaster was pretty good. There were a few rollovers, but no big surprises. My ride on Batman – The Ride ended up being pretty solid; meaning the ride could have been better, but it could have been a lot worse.

Superman Ultimate Flight

Superman Ultimate Flight is the first Sky Rocket II from Premier Rides. You can now experience this ride five times in the USA alone.

The first launch on Superman Ultimate Flight is very similar to the initial acceleration of a modern swing boat, but after the change of direction it is much more powerful and we almost reach the top of the non-inverted loop. With a lot of momentum we are accelerated a third time and after a 180° turn we easily reach the top level of the ride. After a very short breather we enter the inversion of the ride, which is clearly visible from afar, where we experience a very pronounced hangtime. Shortly afterwards we dive back into the non-inverted loop. Another reunion with the apex of the element heralds the finale of the ride, whereupon, after another run through the station, we come to a precise stop and our wild ride comes to an end.

Wonder Woman Lasso of Truth

At the back end of the DC Universe area is Wonder Woman: Lasso of Truth. This giant pendulum ride is a blast; although, the ride is not as diversified as other Giant Discovery rides by Zamperla, as it does rotate only in one direction without varying the speed of the rotation too much.

Joker

The Joker hybrid coaster is a rebuilt version of the Roar wooden coaster, now re-launched with a slightly different layout.

The ride on the RMC I-Box Track rollercoaster begins immediately with a short pre-lift section consisting of several waves and smaller bends. Once we reach a height of 100 ft (30 m), we immediately plunge down a steep curve. We are immediately drawn into a step-up under flip, where we change direction in a brilliant overhead manoeuvre. After a left-hand bend, we are then pulled directly into a zero-G stall, where we experience several seconds of weightlessness while we are once again upside down. Back in the seat, we are immediately pulled into a turning curve consisting of several alternating waves, first to the left and then to the right. This is followed by several airtime hills, which are repeatedly interrupted by larger turning curves. Finally, there is a roll through the rafters and several smaller airtime bumps before we find ourselves in the final brake.

The Joker is a really good rollercoaster. The ride is extremely dynamic and simply great fun without putting too much strain on the passengers. Just like on Kings Dominion’s Twisted Timbers, you can easily do one lap after another here – something you can’t do on every RMC. It’s terrific! 

Flash: Vertical Velocity

Flash: Vertical Velocity is the most unique roller coaster at Six Flags Discovery Kingdom. Originally, the ride opened as V2: Vertical Velocity featured the same layout as the ride in Six Flags Great America. Due to height restrictions, the ride had to be shortened the year after to a maximum of 150 feet (46 m). Interestingly, the spiral runs now at an angle, thus creating an Inversion over the entrance area to the park. Apart of the initial jolt, the ride is a very fun shuttle coaster and should not be missed when visiting the park.

Monsoon Falls

While the ride area to the left of the park’s entrance lacks any theming, apart of the DC comic billboards and the bat mobile, the path towards this area is actually pretty decent with Monsoon Falls being the highlight. This Intamin Spillwater features a nice ride moistening all riders the most efficient way possible.  

White Water Safari, Ark and Boomerang Coast-to-Coaster

Due to the Halloween event, many paths throughout the park functioned as one-way streets, therefore getting to the big ride area to the right of the park took a bit of time. First you had to pass the Wave Swinger, then the closed White Water Safari rapids ride before finally getting to the area where the Ark pirate boat and the Boomerang Coast-to-Coaster is located. Unfortunately, the Vekoma Boomerang was down on my day of visit.   

Sidewinder Safari

The Zamperla Spinning Coaster Sidewinder Safari is the newest addition to the park. The ride features the standard Spinning Mouse layout, which can be found in dozens of installations worldwide. Due to the low capacity of the ride, I only recommend riding this fun coaster, when the wait times are low.  

From this area, the paths split, creating one giant loop around the lake at the back of the park, where the Monkey Business and Thrilla Gorilla flat rides are located and the path along the big Toyota Stadium – where the dolphin show Drench! takes place – leading to the big ride area to the right of the entrance.

Cobra, Kong and Sky Screamer

In this area you find the family coaster Cobra featuring a double-8 track layout, as well as the Sky Screamer Star Flyer and the suspended looping coaster Kong, which is a ride only for the daredevils, as it is quite jolty even for a Vekoma SLC.

Medusa

The last big roller coaster on our tour of Six Flags Discovery Kingdom is the B&M floorless coaster Medusa. The ride on Medusa begins immediately with a short curve out of the station, whereupon the ride’s lift hill awaits us. As soon as we reach a height of 150 ft (45 m), after a small pre-drop and a short bend to the right, we immediately head towards the abyss. An oversized loop is immediately followed by an equally oversized dive loop, which presses us very firmly into our seats. After a large zero-G roll, we are immediately drawn into a sea serpent roll – a very unusual element for a B&M. After a steep turn, we reach a block brake. Without adjusting our speed, we immediately descend another steep turn at the end of which the entrance to the first corkscrew awaits us. After a helix, we immediately enter the second corkscrew and another helix – this time very close to the ground. A short ascent with a left-hand bend then leads us into the braking section.

Medusa is an extremely impressive roller coaster. The ride has a rather unusual layout for a B&M and some very cool elements. Unfortunately, however, the ride is now a little lacking in ride comfort, so that contact with the shoulder restraints is unfortunately unavoidable during the ride, which is why I have only ventured on a few rides on Medusa.

Conclusion Six Flags Discovery Kingdom

Six Flags Discovery Kingdom is the weakest Six Flags theme park I have visited so far. The ride portfolio itself is pretty good and theoretically the park also offers a large zoo similar to the SeaWorld theme parks. However, as I didn’t experience any of this – thanks to the very limited offer on the day I visited – I can’t include this point in my rating. However, the layout of the theme park is relatively strange, thanks to the two large rollercoaster clusters to the right and left of the entrance that were added by Six Flags. The rest of the theme park then goes back to its history as the Marine World theme park.

Going on a Great Adventure

Six Flags Great Adventure

Six Flags Great Adventure has a rather unusual park layout, with visitors entering the park at its narrowest point in the centre. Here there is a long midway that runs across the entrance, with the Giant Wheel at one end and a land of milk and honey themed area with a carousel and a tea cups ride at the other.  The main attraction in this area is the Sky Screamer swing ride.

Wonder Woman Lasso of Truth and Cyborg Cyber Spin

To the right of the Ferris wheel is the large Movieland themed area. In addition to the interactive dark ride Justice League: Battle for Metropolis and the two roller coasters The Dark Knight Coaster and Batman The Ride, there is also the large swing ride Wonder Woman Lasso of Truth and the flat ride Cyborg Cyber Spin. Unfortunately, the latter wasn’t on my schedule during my visit, so I didn’t get to ride an Intamin Tourbillon.

Justice League: Battle for Metropolis

Developed by the Sally Corporation, the Justice League: Battle for Metropolis dark ride combines large plastic scenes with 3D screens where you have to fend off all sorts of Lex Luthor’s gadgets before he manages to capture the entire Justice League with the help of the Joker. It’s great fun, as you’d expect from Sally, and a surprisingly well-made dark ride that can be found in many Six Flags theme parks.

The Dark Knight Coaster

The Dark Knight Coaster is proof that Six Flags can do theme rides when they want to. The indoor Wild Mouse offers an amazingly fast ride in total darkness, with the hairpin turns in the upper part of the ride being themed throughout. The wilder part of the ride on the lower levels takes place mainly in the dark. All in all a great attraction!

Batman The Ride

Directly after the great success of the B&M inverted coaster Batman: The Ride at Six Flags Great America, the Dark Knight found his place at Six Flags Great Adventure in 1993.

After climbing the lift hill, passengers can expect a pre-drop before the train finally plunges down the first drop in a steep curve. On the descent, passengers can expect high G-forces before entering the first loop. The second inversion, a zero-G roll, follows in no time at all. Then another loop is taken. The blood pressure in your feet rises instantly as you go through a steep bend and a straight section of the track. It then heads mercilessly towards the bottom, where the first corkscrew awaits us. This element is pure madness if you are travelling at the back of the train, as the acceleration changes abruptly. The second corkscrew follows after a short right-hand bend. After that, a left-hand bend takes you straight into the braking section.

Batman: The Ride is still one of the best inverted coasters out there. The ride offers an intense ride layout with lots of positive G-forces on a relatively small footprint. Apart from the theming, the ride experience does not differ between the different rides, which is a good sign.

Nitro

Since the release of the computer game Roller Coaster Tycoon 2, Nitro has become one of the most famous hyper coasters in the world.

After a turn, the ride immediately begins on the 230-foot lift hill. Once at the top, the ride immediately descends. Interestingly, we change direction on the very first hill. The momentum takes us through another valley and over a classic camelback before we change direction in the best out-and-back style in a horseshoe turn. Another airtime hill is followed by another hill where we turn left. With plenty of speed we then enter a powerful helix that gets tighter and tighter and ends in a block brake. We then ride a series of very nice airtime hills to the final brake.

Nitro is a very cool old school hypercoaster. Although you only get floater airtime during the long ride, the many hills make it a real experience. The highlight of the ride is the intense helix before the block brake. In short, a really great coaster.

Jersey Devil Coaster

Past the Intamin Rapids Ride Congo Rapids, which was unfortunately closed on the day of my visit, we now head to the park’s newest rollercoaster, the Jersey Devil Coaster. The ride on the RMC Raptor Track begins immediately with the ride’s lift hill. After reaching the starting height of 40 metres in no time at all, we plunge straight down a very steep descent. After a quick ascent, it’s straight back down again in a dive loop. With brutal airtime, we then go over a huge camelback and immediately afterwards into a zero-G stall. A steep ascent then leads us into a very tight turn. Now we descend again quite abruptly and immediately enter a zero-G roll. Another ascent then leads us into a block brake. Without much delay, we then enter the next descent, after which another turn awaits us. Still very fast, we now race over a series of airtime bumps before reaching the final brake.

The layout of the Jersey Devil Coaster single rail coaster has a really nice flow. The inversions are all very easy to ride and the airtime is also very nice. I at least really enjoyed the ride, even if it is a bit tame compared to the other Raptor Track Coasters from RMC.

Skull Mountain

Every Roller Coaster Tycoon player will remember the Skull Mountain indoor roller coaster for its façade. The ride itself is a family roller coaster from Intamin, which is located in an unfortunately rather bright hall.

The ride begins rather curiously with a two-section lift and a short panoramic ride through the first level. Once in the main hall, the ride continues upwards for a while before a steep curve takes you straight back down to the hall floor. After an incline, we quickly change direction and make our way round a wide left-hand bend. After a short right-hand bend, we immediately enter a longer Bayernkurve, which leads us further and further downhill over hill and dale. After a right-hand bend, we enter a helix. Finally, after a short climb, we reach the braking section and soon afterwards the station, where our wonderful ride unfortunately comes to an end.

Harley Quinn Crazy Train and The Joker

Directly opposite the popular family coaster Harley Quinn Crazy Train – a Zierer Tivoli coaster that has run several laps in a row in this park – is the S&S free spin coaster The Joker. As always, the ride comfort on this coaster was quite good and there were plenty of rollovers at the end. For this reason, I can only warmly recommend a ride on the free spin coaster The Joker.

Houdini’s Great Escape

While Vekoma Mad Houses are a very common sight in European theme parks, they are not at all well known to an American audience with Houdini’s Great Escape being one of only two installations in the United States. In the story, we take part in a séance to bring Houdini back from the afterlife. In reality, however, we only experience a clever trick in which the benches each swing 30° to the side while the room rotates around us. A great attraction!

Twister and Parachute Training Center: Edwards AFB Jump Tower

Right next to the unfortunately closed HUSS Top Spin Twister is one of the park’s major attractions from the 1970s, which goes by the long name of Parachute Training Centre Edwards AFB Jump Tower. The Intamin Parachute Tower offers a great view over the park and the ride is quite fast. The actual drop, however, is very leisurely.

Superman – Ultimate Flight

Superman Ultimate Flight is located next to the entrance. As it takes a little longer to clear the coaster, it is advisable to get to the ride as soon as the park opens.

The ride on Superman Ultimate Flight begins immediately after a right turn as you enter the coaster’s lift hill. After reaching a height of 106 ft, the ride immediately descends in a right turn. The ride then climbs a hill, which introduces the main element of the ride: the Pretzel Loop. We are now pulled down with all our might and then hurtle through a valley on our backs. Once back up in the air, the ride takes us through three very gentle turns that add to the feeling of flying. A helix is followed by a nice roll. We then reach the braking section and shortly after the station.

The ride on Superman Ultimate Flight is very leisurely for a flying coaster, with the pretzel loop at the beginning being the highlight of the ride. Without it the ride would be a bit boring.

Green Lantern

The Green Lantern stand-up coaster has been located on the site of the Great American Scream Machine since 2011. However, the ride itself is much older and was located at Six Flags Kentucky Kingdom from 1997 to 2009, where it was known as Chang.

The ride on the giant stand-up coaster starts right away with the lift hill, which takes us to a height of 47 metres (154 ft). After a bend at a lofty height, the big drop awaits. In classic B&M coaster style, a very large loop awaits us and after a right-hand bend we enter the equally large dive loop. After a sweeping ascent, we pass through a high left-hand bend and immediately afterwards into an Inclined Loop. After a quick change of direction, the route then heads uphill again into a mid-course brake. Without adjusting the speed, we head downhill again. Here we enter the first corkscrew and after a crazy right-left bend, we immediately enter the second corkscrew. Another right-left bend then takes us into the final braking section of the rollercoaster.

Green Lantern is one of the most modern stand-up coasters, so the ride is relatively fast. The ride is very spectacular due to the impressive height and the huge inversions, but not quite as pleasant due to the frequent contact with the bars.

Runaway Mine Train

One of the theme park’s original attractions is the Runaway Mine Train. It is housed in a large fort. There is also a station for the Skyways gondola lift.

The ride on the rollercoaster begins with an unusually high lift hill. Once at the top, however, we first make our way through the treetops. The path first leads us through a long helix and then over several hills. After passing a block brake, we fall to the ground for the first time. Now the trail leads us into a surprisingly intense helix and over a flawless airtime hill. We then whizz over the lake past the fort before taking an incline and reaching the braking section of the rollercoaster shortly afterwards.

The Runaway Mine Train has a surprisingly high layout for an old school mine train. Although the start of the ride is not quite as exciting with the longer helix and the slightly descending and ascending straights, it gets really fast from the steep curve after the brakes. The Airtime hill and the bend at the lake around the fort characterise the overall very good ride.

Medusa

Passing the Saw Mill Log Flume, which was unfortunately still closed on the day of my visit, we now head to the back of the park, where the Medusa roller coaster is located. This rollercoaster is quite something and should definitely not be missed.

It is not to be missed. After climbing the coaster’s lift hill, you immediately descend into the depths. The ride takes you through the valley at high speed and immediately into the large loop of the coaster. A climb to the left turns out to be a dive loop and immediately brings us to the ground. With a lot of momentum we then go through a Zero-G roll and immediately into the Cobra Roll of the coaster. A climb then leads us into a block brake, where we get only a brief moment to catch our breath. A steep bend takes us downhill. We then enter an intense helix just above the ground. After changing direction we enter the Interlocking Corkscrews. A short turn to the left then leads us into the last incline of the ride, after which we enter the braking section of the roller coaster.

What a ride! The Medusa floorless coaster is an absolute fun machine with a breathtaking layout and a total of seven inversions. I always enjoyed getting on this ride, partly due to the very efficient handling of the ride.

Zumanjaro Drop of Doom

Unfortunately, the Zumanjaro Drop of Doom freefall tower, which is attached to the support structure of the KingdaKa rollercoaster, was out of service during my visit. This tower is the largest freefall tower in the world. Interestingly, in the early days of the attraction, the tower was only allowed to be operated when the rollercoaster was not in operation. This led to long queues for both attractions. However, this restriction has now been lifted and both rides can be operated at the same time.

Kingda Ka

Kingda Ka has been the theme park’s main attraction since 2005. The 456 ft high launch roller coaster from the manufacturer Intamin towers over the park and cannot be overlooked, casting a spell over everyone in its immediate vicinity.

Right at the start of the park, I was able to ride several laps in a row without having to queue for long. After all, the ride only takes a few seconds, during which you reach a top speed of 128 mph before climbing the tall Top Hat. We then cross its apex rather leisurely and with tension on the vertical slope directly in front of us. On the way down, we turn round once on our own axis. Finally, we race over a 130 ft high hill where the roller coaster brakes.

Kingda Ka is a damn short roller coaster, but also a damn good one. As the speed increases, you realise what forces are acting on the train before it goes up the top hat. You are really shaken up. The descent and the final rush of speed also provide enough endorphins to leave the ride overjoyed.

El Toro

Five years after Colossos revolutionised wooden roller coaster construction at Heide-Park in Germany, the El Toro roller coaster opened at Six Flags Great Adventure in 2006.

Here, too, the ride begins after a rapid lift hill with a high turning curve before entering the steep drop. We then experience the finest airtime and an unrivalled rush of speed over two consecutive airtime hills. After a lively turn, we ride over another airtime hill and then over a speed bump. At high speed, we are now drawn into a left-hand bend and immediately afterwards onto another airtime hill. This is followed by three quick turns in a row. With momentum, we then ride over a series of rather flat hills. Shortly afterwards, we reach the braking section of the rollercoaster.

El Toro is a really great rollercoaster with a genuinely good layout. Unfortunately, the ride characteristics of this wooden roller coaster are no longer the best compared to the other Prefab wooden roller coasters from the manufacturer Intamin. Despite being retracked during the seasonal break, the ride is quite bumpy. Accordingly, I like Colossos much better than El Toro, and not just because I have ridden Colossos hundreds of times and El Toro only once.

Conclusion Six Flags Great Adventure

My visit to Six Flags Great Adventure left me with rather mixed feelings. On the one hand, the park has a lot of really good roller coasters to offer, but on the other hand, the park simply has no charm. The existing buildings are all getting on in years, and the park really does have a lot of open spaces and lots of areas covered in concrete. Nevertheless, the park is very popular and was accordingly well attended on the day I visited. In the end, I was able to try out all the attractions except for the water rides, which were unfortunately closed. I think I’ll have to come back sometime in the middle of the season to experience the park in its entirety.
