It has a variety of [[roller coaster]]s and other [[amusement ride]]s, with a number of animal exhibits and shows. It has been part of the [[Six Flags]] chain of amusement parks since 1999. ==History== ===Early history=== {{details|Marine World/Africa U.S.A., California}} The park first opened in 1968 as '''Marine World''', a small oceanarium in [[Redwood City, California]]. In the mid-1970s, they merged with a failing land-animal park called [[Marine World/Africa U.S.A., California|'Africa, USA']], and became '''Marine World Africa USA'''. In late-1985, the increase in the value of the property the park occupied became too great a tax burden. Following an intensive search for a new site, construction began on a new and larger park facility in [[Vallejo, California]] (about {{convert|55|mi|km}} north from Redwood City). The new Marine World opened to visitors in 1986, and remained under control of the non-profit Marine World Foundation, using [[Garfield]] as a mascot at various points. The park defaulted on its debt to the City of Vallejo, and thus became owned by the city, in 1996. ===Conversion to a theme park=== The city then hired [[Premier Parks]] (now known as Six Flags Inc.) to manage the park, upgrade it, and improve its attendance. Premier added some non-animal attractions, particularly amusement rides, to increase attendance. In 1997, the park added two major ride attractions, "[[Popeye]]'s Seaport" and "DinoSphere". Popeye's Seaport offered eleven children's attractions, including an interactive foam ball play structure and an interactive water play area. DinoSphere took the place of the park's Australian Walk-A-Bout attraction (also the former home of the "DINOSAURS!" attraction). DinoSphere was an [[Iwerks]] Turbo Theater, capable of seating 100 riders per showing. The theater played the Iwerks film called "Dino Island" for its first season of operation (the theater has since changed films numerous times). The number of amusement rides increased over the next few years, including the addition of several major [[roller coaster]]s. In 1998, the park's name changed again, this time to '''The New Marine World Theme Park'''. The 1998 season saw the addition of two major roller coasters, [[Kong (Six Flags Discovery Kingdom)|Kong]] and [[Boomerang: Coast to Coaster]]. Kong was relocated from [[Opryland USA]] after that park shut down in 1997 and opened at the Marine World in May 1998. Other major additions that year included Hammerhead Shark, a [[Zamperla]] Prototype Hawk 48; VooDoo, A [[HUSS Maschinenfabrik|HUSS]] [[Top Spin (ride)|Top Spin]]; Monsoon Falls and White Water Safari, [[Intamin AG]] water attractions. DinoSphere also received a new ride film, "Dino Island II: Escape from Dino Island" which featured improved graphics along with a new storyline. ===Addition to the Six Flags chain=== [[Image:roar1.jpg|thumb|Roar Wooden Roller Coaster]] After more additions of amusement rides, Premier made a name change to '''Six Flags Marine World''' in 1999. The most notable result of the name change was the rights to [[Warner Bros.]]' [[Looney Tunes]] characters. With the new name, the park received the wooden roller coaster called [[Roar (Six Flags Discovery Kingdom)|Roar]]. Built by Great Coasters International Inc., it was the first coaster to feature [[Millennium Flyer]] trains. The 1999 season also saw the introduction of Tasmanian Devil, a Frisbee flat ride manufactured by [[HUSS Maschinenfabrik|HUSS]], and Scat-A-Bout, a typical Scrambler flat ride. Although both rides opened in 1999, they were purchased by the park in 1998 but not constructed until 1999 because of construction timetables that prevented them being constructed in time for the 1998 season opening. Popeye's Seaport was rebranded "Looney Tunes Seaport" and received the Roadrunner Express kiddie coaster. In 2000, the park opened its fourth major roller coaster dubbed [[Medusa (Six Flags Discovery Kingdom)|Medusa]]. Medusa was built by [[Bolliger & Mabillard]]. Medusa lasts three minutes, starting with a 150 foot drop and is the park's most visited ride.{{Verify source|date=July 2007}} With the addition of Medusa, the park also received the Cobra family coaster and built a new parking lot south of the park. The park received its fifth major roller coaster in 2001, [[V2: Vertical Velocity]]. Built by Intamin AG, the ride was the first "Spiraling Impulse Coaster" on the west coast and took the record for being the tallest and fastest coaster in Northern California. The ride was plagued with technical issues when it opened, which resulted in extensive down time. The park also eventually turned off the LIM motor on the back tower that held the train in position for a few seconds on its second trip up the tower.{{Verify source|date=July 2007}} The park also added the "Warrior of the Dawn" film to its DinoSphere theater. 2002 saw a notable modification to Vertical Velocity. Because of local building restrictions, the height limit on all roller coasters at the park is {{convert|150|ft|m}}, while V2 exceeded that limit by about {{convert|36|ft|m}}. Thus, they lowered the reverse tower {{convert|36|ft|m}} and turned the forward tower into a 45° angle with an incline heartlineroll that spiraled over the park's main entrance. So far, Vertical Velocity is the only roller coaster to do this. The park turned the LIM motor on the reverse tower back on in 2002 season; however the motor failed to hold the train completely in place and slipped significantly. The motor was eventually turned off again in the 2003 season.{{Or|date=September 2007}} Also the park began to show "7th Portal" in its DinoSphere Theater. The park added its sixth major roller coaster, Zonga, in 2003. The ride created by Schwarzkopf, was relocated from [[Six Flags Astroworld]], and received major track modification by Premiere Rides before it opened at Marine World. Zonga opened in late April to a sporadic operation. The ride was often closed because of mechanical problems, and when it did operate, it often closed for short periods of time due to ride errors. Eventually the park delayed its opening to 12 noon every day, completely blocking the ride plaza to park guests. Zonga's last season of operation was 2004, it then sat dormant until it was removed in 2006 and placed in the parking lot for storage. By the beginning of the 2007 season, Zonga was removed from the parking lot. It is now operating at the San Marcos National Fair in Mexico. The park also began showing "Stargate SG3000" in its IWerks 3D Turbo Theater which finally received new branding and was no longer called "DinoSphere". Stargate, however, did not feature the 3D effect and rarely received good reviews from guests. {{Or|date=September 2007}} 2006 saw the addition of Tava's Jungleland, a children's area located in the back of the park near the main land animal attractions, featuring nine new attractions for families and small children to enjoy. ===Rebranding to Discovery Kingdom=== [[Image:DK From Parking Lot.JPG|thumb|Discovery Kingdom, seen from the parking lot]] On [[January 17]], [[2007]], the park announced its new name, "Six Flags Discovery Kingdom." The new name reflects the image of an animal park, a thrill-ride park, and a marine park. The park was separated into different themed lands of Land, Sea and Sky. $16 million was spent on park improvements including new signage, new shows, and converting the 3D theater into a "4D" theater. The park also added a [[Thomas the Tank Engine]]-themed children's area called Thomas Town, which opened [[June 20]] [[2007]]. The animal aspects of the park have not vanished under this onslaught of steel and lights, and the park continually adds animal attractions every year. Discovery Kingdom continues to showcase its marine mammals and is currently home to the [[orca]] Shouka, who was at the Six Flags park in Ohio until 2004. In 2005, the park added "Ocean Discovery", a major interactive marine animal area that lets guest interact and pet [[sting ray]]s and Atlantic [[bottlenose dolphin]]s as well as getting up close to [[South Africa]]n [[penguin]]s. On [[June 5]], [[2007]], Six Flags confirmed media reports that Six Flags will exercise their option to buy the park.<ref name="Vallejo Times">{{cite news|url=http://web.archive.org/web/20070609160503/http://www.timesheraldonline.com/ci_6073730|title=Six Flags to buy Discovery Kingdom|last=Brown|first=J. M.|date=June 6, 2007|publisher=Vallejo Times Herald|accessdate=2008-12-08}}</ref> For 2008, the park featured its longest operating season since it was branded as a Six Flags park. The park has shut down the IWerks 3D Turbo Theater due to escalating repair costs on the out of date operating system and hardware. The park received its 8th roller coaster named Tony Hawk's Big Spin, which is located on the former Zonga concrete pad. The ride features a unique layout compared to the three other coasters which share the name, including a base frame instead of permanent concrete footers and a higher top speed. Tony Hawk's Big Spin opened on [[May 23]], [[2008]]. In 2009, the park introduced the all new Odin's Temple of the Tiger. The new tiger exhibit and show features the diving, white tiger named Odin. Discovery Kingdom also acquired two new Bengal tiger cubs, Nalin and Akasha. 2009 also saw the addition of the park's official page on Facebook. Fans of the park can stay up to date with all the latest news, updates, and photos from Discovery Kingdom. http://facebook.com/discoverykingdom The park's major competition in the [[San Francisco Bay Area]] is [[California's Great America]] in [[Santa Clara, California|Santa Clara]], next to [[San Jose, California|San Jose]]. ===Seasonal Events=== The haunt at Discovery Kingdom is their annual '''Fright Fest''' Halloween event. Two haunted houses, scare zones, and many ghouls are added throughout the park. Tinseltown Terror haunted house is located in the park's bumper car ride. Brutal Planet haunted house is normally located in the Roar plaza near where Zonga used to be. The scare zone is located between Ocean Discovery and the entry plaza. This is where the world famous cockroach eating contests are held. 2009 will see the replacement of the two old haunted houses. Two new houses will be introduced in October. New for 2007, Discovery Kingdom introduced the Wheel of Fright and the Coffin of Fear for Fright Fest. 2007 also brought the addition of the Kamp Khaos haunted house, replacing Brutal Planet. Kamp Khaos was also placed in a new location for a Haunted House, inside the Monsoon Falls water ride lagoon. The other major seasonal event, '''Holiday in the Park''', made its debut November 23, 2007. The event featured Santa Claus, holiday themed shows, and other seasonal treats. Discovery Kingdom also featured the world's largest [[Christmas tree]] as part of the celebration. The tree was {{convert|125|ft|m}} tall and had a diameter of {{convert|4|ft|m}}. Due to its size, a [[Chinook helicopter]] was needed to set it into place.<ref>{{cite press release |title= Six Flags Discovery Kingdom to Present the Biggest Christmas Tree in the World |publisher= [[PR Newswire]] |date= [[2007-10-22]] |url= http://money.cnn.com/news/newsfeeds/articles/prnewswire/NYM03722102007-1.htm |accessdate= 2007-11-05 }}</ref> ==Rides and Attractions== ===Roller Coasters=== * '''[[Boomerang: Coast to Coaster|Boomerang]]''' - A [[Vekoma]] [[Boomerang (roller coaster)|Boomerang]] clone. This was the first roller coaster to open at the park. * '''[[Kong (Six Flags Discovery Kingdom)|Kong]]''' - A Vekoma Suspended Looping Coaster and the second roller coaster to open at the park. Kong was relocated from the defunct [[Opryland USA|Opryland Themepark]] in Nashville, Tennessee where it was called [[The Hangman (roller coaster)|The Hangman]], following the 1997 operating season. In 2007 the ride's entrance was moved to Oasis Plaza near Medusa. Riders now walk under the ride to enter. * '''[[Roar (Six Flags Discovery Kingdom)|ROAR!]]''' - A wooden coaster built by Great Coasters International Inc., ROAR! was the first coaster to feature millennium flyer trains. While the ride is a near clone of [[Six Flags America]]'s ride of the same name, Marine World's version was designed with tighter turns to enhance the feeling of speed. ROAR! is the tallest, fastest, and longest wooden roller coaster in Northern California. [[Image:MedusaDiscoveryKingdom2007.JPG|thumb|[[Medusa West|Medusa]] Roller Coaster]] * '''[[Medusa West|Medusa]]''' - Built by [[Bolliger & Mabillard]] of [[Switzerland]], Medusa stands {{convert|150|ft|m|abbr=on}} tall and reaches speeds of {{convert|65|mi/h|km/h|abbr=on}}. When the ride opened in 2000, it featured the tallest vertical loop in the world at {{convert|128|ft|m|abbr=on}} tall. Medusa used to share its name with its sister coaster at [[Six Flags Great Adventure]] (before it was converted to Bizarro) but features a different layout. The ride was the first coaster to ever feature the "Sea Serpent" element, a variation of B&M's popular "Cobra Roll" element. At 3,985ft long, Medusa is the longest roller coaster in Northern California and shares the height record with V2: Vertical Velocity, also located at the park. * '''[[V2: Vertical Velocity]]''' - California's first and only Spiraling Impulse Coaster, Vertical Velocity was built by [[Intamin AG]] and opened in 2001. It stood {{convert|186|ft|m|abbr=on}} tall and reaches speeds of up to {{convert|70|mi/h|km/h|abbr=on}}. In 2002, the park was forced to modify the ride so that it no longer exceeded {{convert|150|ft|m|abbr=on}} due to local height restrictions. In doing so the front tower was tilted to a 45-degree angle and the reverse tower lowered to {{convert|150|ft|m}}. The ride still holds the record for Fastest Coaster in Northern California at {{convert|70|mi/h|km/h|abbr=on}} {{Citation needed|date=September 2009}}and is tied with Medusa for Tallest Coaster in Northern California. * '''[[Tony Hawk(Six Flags Discovery Kingdom)|Tony Hawk's Big Spin]]''' - Opened on May 23, 2008, this spinning coaster themed to the legendary skateboarder will take riders in four-passenger "Skateboards" and spin them through over {{convert|1300|ft|m|abbr=on}} of track at {{convert|31|mi/h|km/h|abbr=on}}. The ride will also have onboard DVD video that riders will be available for purchase, this feature can also be found on other Tony Hawk rides at sister Six Flags parks in St. Louis, Arlington and San Antonio. This Tony Hawk's Big Spin has also been awarded by the National Six Flags Corporation as the friendliest and cleanest of them all. In comparison to other Tony Hawk rides, this one puts on more riders per hour than any other, totaling around 400-550 people per hour. * '''[[Cobra (Six Flags Discovery Kingdom)|Cobra]]''' - A {{convert|26|ft|m|abbr=on}} tall family coaster located in Oasis Plaza, Cobra opened in 2000. * '''[[Road Runner Express (Six Flags Discovery Kingdom)|Roadrunner Express]]''' - A kiddie coaster located in the park's Looney Tunes Seaport section.
