There aren't any major theme parks in the state of Washington. For that, you'd have to head elsewhere, such as California to visit parks such as Universal Studios Hollywood. There aren't any huge amusement parks either. (In case you're wondering there is a difference between theme parks and amusement parks.) Again, you could head down to California to enjoy major thrill parks such as Six Flags Magic Mountain.
There are, however, some places in the state of Washington where you could find roller coasters and other fun. There are a few places to cool down and enjoy water slides and other water park fun as well.
A relatively small water park, Birch Bay doesn't have marquee attractions such as water coasters, surfing simulators, a bowl ride, or a funnel ride. But it does include a collection of slides and attractions for various ages and thrill tolerance levels. Highlights include the Black Hole enclosed tube slide and the harrowing Hydrodrop speed slide. Younger kids will enjoy the activity pool and the kiddie pool
Great Wolf Lodge Grand Mound is a good-sized water park that is part of the Great Wolf Water Park Resorts chain. It is located on the Chehalis Reservation. Attractions include body slides, kiddie slides, tube slides, a wave pool, a lazy river, a funnel ride, whirlpool spas, and an interactive play structure with tipping bucket. Park admission is included in the hotel rate and is open to registered guests only.
It started as a farm and fruit stand, but Remlinger Farms has grown to include a market, restaurant, and a small family fun amusement park. Rides include a small roller coaster, a steam train, and a Ferris wheel.
Riverfront Park is a publicly run amusement park on the banks of the Spokane River (and the former site of Expo '74) It includes an IMAX large-screen theater, a carousel, Ferris wheel, bumper cars, a Dragon roller coaster, and a few other rides.
Located at Pier 57, the Seattle Great Wheel is a standalone attraction. Each cabin on the observation wheel seats eight passengers, and the ride includes three revolutions and lasts about 15 minutes. Other things to do at the pier include Wings Over Washington, a “flying theater” ride that simulates hang gliding above the state, as well as restaurants and shops.
Slidewaters is a medium-sized park. Attractions include a mat racing slide, a lazy river, body and tube slides, and a 60-person hot tub.
Splash Down is a fairly small park with a bowl ride, a speed slide, body slides, a Water Wars game, and a kids play area.
A medium-sized municipal water park, Surf 'n Slide offers a Flowrider surfing simulator, a lazy river, water slides, an interactive water play structure, slides and play areas for young children, sand volleyball, and a large swimming pool.
It's only open a few days in the late summer/early fall and again in the spring. The popular fair has permanent rides (as opposed to the traveling carnival rides found at most state fairs) that include the Classic Coaster, a woodie that dates back to 1935, and the Rainier Rush, a steel coaster that includes a loop. There is also an antique carousel, the Extreme Scream drop tower, a bunch of flat rides, and Sillyville, an area for small children.
Wild Waves and Enchanted Village is a medium-size amusement park with a large water park. It used to be run by Six Flags. Among the featured rides is Timberhawk, a wooden coaster. On the water park side, Wild Waves offers the Zooma Falls family raft ride and and Hook's Lagoon, an interactive water play center, among other attractions. Tickets are available for the theme park only or for both the water park and the theme park combined. Single-day tickets for just the water park are not available.
Defunct Washington Parks
There used to be more amusement parks in the state. Luna Park, which was located in Seattle, for example, used to feature the Great Figure 8, a wooden coaster. It closed in 1913. The accompanying image was taken in 1910.
Another early 20th century park, White City in Bellingham, also offered a wooden coaster. Fun Forest, which was located at the base of the Space Needle in Seattle, had coasters and other rides for many years but closed in 2011.
