There aren't any major theme parks or amusement parks in Alabama. The bigger properties are really more water parks than amusement parks. Still, if you are looking for roller coasters and other thrills, here is where you could find them. Parks are listed in alphabetical order.
Alabama Splash Adventure
Bessemer (near Birmingham), Alabama
New for 2016: Drop Zone, a 30-foot-tall drop tower ride, and a spinning teacups ride.
As its name implies, Alabama Splash Adventure is primarily a water park. In addition to its water slides, wave pool, lazy river, and other wet fun, the "dry" rides include a mini train, bumper boats, the Wacky Worm kiddie coaster, and its signature attraction, Rampage, a well-regarded wooden roller coaster. One price includes all attractions, and the park offers free parking, free sunscreen, and complimentary soft drinks.
Once Alabama's biggest amusement park, it has an interesting history. It opened in the late 1990s as a municipally owned facility known as VisionLand. It ran into financial difficulties not long after it debuted and filed for bankruptcy in 2002. Private owners purchased the park and operated it starting in 2003. In 2006, it was re-branded as Alabama Adventure and later, Alabama Adventure Water and Theme Park. In 2012, the park changed ownership again. The new operators renamed it Splash Adventure, closed most of the amusement park rides, and focused on the water park.
In 2014, some members of the family that had run Holiday World in Indiana purchased the park and changed its name once again (whew, this park has sure had a lot of names!) to Alabama Splash Adventure. It has been slowly reopening the amusement park rides such as Rampage (which means another name change may be coming). The new owners say that they have plans to expand the park.
The small park is open year-round, although it is closed mid week in the off-season. Attractions include mini-golf, go-karts, bumper cars, batting cages, and carnival rides. Water slides and other water park rides are open in the warmer months.
The small park features a train, splash pad, carousel, and a kiddie coaster.
Gulf Shores, Alabama
Another Alabama park that is primarily a water park. Among its featured attractions are a Flowrider surfing ride, a wave pool, a lazy river, and the Screamin' Demon speed slide. The dry rides include Cannonball Run, a wooden coaster that hits 50 mph, plus mini-golf, kiddie rides, go-karts, and a bungee trampoline.
