Rising beneath a massive curved barrel-vault glass enclosure in Grand Prairie’s 172-acre EpicCentral district, Epic Waters Indoor Waterpark offers an 80,000-square-foot tropical escape 365 days a year. Nicknamed the “cruise ship on land,” this municipal aquatic facility eliminates the biggest headaches of water park visits: sunburn, rain cancellations, and freezing winter temperatures.
With the entire interior maintained at an 85-degree climate, guests can ride record-breaking speed slides, catch endless surf waves on the FlowRider, float along a 600-foot lazy river, or relax in private rental cabanas regardless of whether it is 105 degrees in July or 35 degrees in January.

What to Expect at Epic Waters Indoor Waterpark in Grand Prairie
Epic Waters serves as the flagship recreational centerpiece of EpicCentral, Grand Prairie’s entertainment corridor. Opened in 2018, the facility was designed to offer world-class resort water park amenities at accessible municipal rates.
Travelers exploring the surrounding entertainment zone can review neighboring outdoor attractions, illuminated lake shows, and dining spots in our master guide to things to do in Grand Prairie.
The 80,000-Square-Foot Year-Round Tropical Oasis
The sheer scale of the indoor complex is striking from the moment you pass through turnstiles:
- Massive Water Volume: The park houses 11 major water slides, a 10,000-square-foot outdoor wave pool (Waves of Fun, open seasonally), and a 600-foot lazy river carrying over 300,000 gallons of filtered water.
- Tropical Landscaping: Lush palm trees, stone waterfalls, and resort-style sun loungers wrap around the water features, creating an authentic resort atmosphere.
- Family Amenities: A full-service arcade with over 45 redemption games, an on-site cafe, and a sports bar provide land-based entertainment between swim sessions.
The OpenAire Retractable Polycarbonate Roof
The engineering anchor of the facility is its curved OpenAire retractable roof system:
- Natural Sunlight: The 80-foot-tall curved barrel vault is clad with multi-wall polycarbonate panels that allow natural sunlight to illuminate the pools without trapping harmful UV radiation.
- Operable Panels: During sunny, pleasant spring and early summer days, motorized roof panels slide open to circulate fresh breezes.
- Winter Insulation: During colder autumn and winter months, the roof seals tight, creating a greenhouse effect that retains warmth while specialized HVAC dehumidifiers keep indoor air fresh.

Lassoloop: The Tallest Indoor Looping Body Slide in the Nation
Standing at the pinnacle of the slide tower, the Lassoloop is the undisputed headliner of the park:
- The Launch Capsule: Riders step inside a vertical glass launch chamber suspended nearly 70 feet in the air. You cross your arms over your chest as a digital countdown echoes through the capsule.
- The Trapdoor Drop: Without warning, the floor drops out beneath your feet, plunging you into an almost vertical free fall that reaches speeds topping 35 mph.
- The Inclined Loop: Massive gravitational force propels you through a 360-degree upward-sloping loop before sliding to a smooth halt in the deceleration flume. It is one of the most intense indoor water attractions on the continent.
Prairie Plunge, Texas Twist, and Yellowjacket Drop
Beyond the Lassoloop, the slide tower features a lineup of intense flumes:
- Prairie Plunge: An enclosed body speed slide where riders drop 60 feet down a near-vertical chute into darkness before bursting out into daylight.
- Texas Twist: A high-speed enclosed twisting tube slide that sends single or double tubes banking through rapid 360-degree corkscrew curves.
- Yellowjacket Drop: An enclosed combination tube ride that shoots riders through dark tunnels before launching them up a steep zero-gravity banking wall where tubes hang suspended before descending into the splash pool.
Rio Grand Lazy River and Rascal’s Round-Up for Toddlers
Guests looking for gentle recreation have dedicated zones designed for relaxed play:
- Rio Grand Lazy River: Spanning 600 feet, this is one of the longest continuous indoor lazy rivers in Texas. Guests can grab complimentary single or double tubes and float beneath water fountains, tipping buckets, and gentle rapids.
- Rascal’s Round-Up: A multi-level aquatic playground built specifically for toddlers and young children. It features pint-sized body slides, shallow splash pads, water cannons, and a giant 300-gallon tipping bucket that drenches the deck every few minutes.
The FlowRider Surfing Simulator: Bodyboarding and Stand-Up Surfing
One of the signature attractions at Epic Waters is the FlowRider, a stationary surfing wave that pumps tens of thousands of gallons of water over a tensioned composite surface to create an endless rideable wave.
Visitors looking to pair athletic water sports with major league spectator entertainment can easily cross into Arlington, as covered in our guide to AT&T Stadium tours and Rally Days.
How the Continuous Sheet-Wave Operates
The FlowRider generates a three-inch sheet of high-velocity water flowing uphill over a contoured padded hill:
- Cushioned Safety: The riding surface consists of a flexible composite membrane stretched over foam padding, ensuring safe wipeouts for beginners.
- Bodyboarding (Boogie Boarding): Guests lie on their stomachs or drop to their knees on specialized boards, steering by leaning their hips into the rushing wave.
- Stand-Up Flowboarding: Advanced riders stand on skate-style flowboards without fins, carving turns, performing 360-degree spins, and catching air off the wave lip.
Height Requirements, Coaching, and Flow Tour Competitions
To ensure rider safety, strict physical requirements are enforced:
- Height Rules: You must be at least 42 inches tall to bodyboard, and at least 48 inches tall to attempt stand-up surfing.
- Staff Guidance: Certified lifeguards and surf coaches are stationed at the wave at all times, holding hands with beginners to help them find balance before letting them ride solo.
- Competitive Events: Because of its world-class wave mechanics, Epic Waters regularly hosts regional and national stops on the Flow Tour, welcoming competitive surfers from across the globe.

Tickets, Day Passes, and Cabana Rentals Math

Full-Day Passes vs. Twilight Evening Discounts
Epic Waters offers several ticketing options:

Towel Rentals, Locker Costs, and Life Jackets
Packing the proper swim essentials prevents extra expenses inside the gates:
- Towel Policy: Epic Waters does not provide free towels. Guests must bring their own beach towels from home. If you forget towels, souvenir beach towels are available for purchase in the retail shop.
- Electronic Lockers: Digital rental lockers are located in the changing rooms and main pool concourses. Small and large lockers range from $12 to $18 per day with keyless wristband access.
- Complimentary Life Jackets: U.S. Coast Guard-approved life jackets are provided free of charge in multiple sizes, from infant to adult XL, along the lazy river concourse. Children under 42 inches are strongly encouraged to wear life jackets.
Outside Food Policies, Hungry Wave Cafe, and Longboards Bar
To uphold health inspection codes, outside food and beverages are restricted:
- Food Restrictions: No outside coolers, fast-food bags, or prepared meals are permitted through the security checkpoint. Exceptions are made for baby formula, baby food jars, and factory-sealed plain water bottles.
- Hungry Wave Cafe: The indoor counter-service restaurant serves hot pizzas, gourmet burgers, chicken tenders, fresh salads, and ice cream treats.
- Longboards Bar: Adults aged 21 and older can order craft beers on tap, frozen margaritas, piña coladas, and specialty cocktails to enjoy poolside.
