Splashers of the South Sea's brings year-round aquatic fun to Grand Forks with its spacious 40,000 square foot indoor facility. The tropical theme creates a nice escape from North Dakota's harsh winters, complete with palm trees and island-inspired decor that transports you somewhere warmer. The park caters primarily to families with younger kids, though there's enough variety to keep older children entertained too. You'll find a good mix of water slides ranging from gentle kiddie slides to more thrilling tube rides that twist and turn through the facility. The kids' area is particularly well-designed with smaller slides, water features, and interactive play structures that keep toddlers and elementary-age children busy for hours. The wave pool provides that ocean experience without the actual ocean, generating gentle waves perfect for floating or body surfing. Their lazy river winds around a good portion of the park, giving you a relaxing way to take in the tropical atmosphere while cooling off. The facility stays comfortably warm year-round, typically around 82-84 degrees, which feels amazing when it's below zero outside. Since it's fully enclosed, you don't need to worry about sunscreen, but the humidity can be intense, so stay hydrated. The food court offers typical water park fare like pizza, burgers, and snacks, though prices run higher than you'd pay outside the park. Lockers are available but fill up quickly on weekends and holidays, so arrive early if you want prime real estate near the main attractions. The changing rooms are spacious and clean, which isn't always a given at smaller parks. What sets Splashers apart from other regional water parks is its commitment to maintaining that tropical vibe even in the dead of a North Dakota winter. The theming feels authentic rather than cheesy, and the staff genuinely seems to enjoy creating that vacation atmosphere for visitors.

Best time to go

Save money
Online tickets typically save you a few dollars over the gate price; even at lower-priced parks it adds up for a family. Indoor and resort parks routinely run weekday flash sales, military and first-responder discounts, and second-day passes — check the deals page before booking.
