Seven Clans Casino and Waterpark in Thief River Falls offers a unique combo that's pretty rare in the water park world - you can hit the slots while your kids burn energy in a decent-sized indoor water park. The 40,000 square foot aquatic center stays a comfortable temperature year-round, which is a huge plus when you're dealing with Minnesota winters. The water park leans heavily toward younger kids and families, with a sprawling kiddie area that includes small slides, water features, and plenty of shallow play zones. There's a good-sized pool for swimming and a hot tub where adults can actually relax. The slides here aren't massive thrill rides, but they're perfect for elementary school kids who want something more exciting than a splash pad. What makes this place stand out is the convenience factor for families. Parents can take turns watching the kids and trying their luck at the casino next door. The facility is clean and well-maintained, though it doesn't have the bells and whistles of bigger resort water parks. Food options are limited to basic snack bar fare, so don't expect gourmet dining. The staff is friendly and the lifeguards are attentive. Since it's attached to a casino, the crowd tends to be more local families and casino visitors rather than destination travelers. Parking is free and plentiful. The changing rooms are adequate but not luxurious. If you're staying in the area and have younger kids, it's a solid option for a few hours of fun. Just manage expectations - this isn't a massive water park destination, but it serves its purpose well as a family-friendly amenity that pairs nicely with the casino.

Best time to go
Indoor parks shine on rainy weekends and school breaks — exactly when everyone else has the same idea. For shorter lines, aim for a Tuesday or Wednesday morning, or evening hours after 4pm when day-passers start clearing out.
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.
Getting there
Seven Clans Casino and Waterpark sits in Thief River Falls, Minnesota. Resort parking is usually free for overnight guests and ranges from $10–25 for day visitors. If you're a day visitor, ask the front desk about validating parking at the spa or restaurant — sometimes that's faster than the standard exit.
Who it's best for
Fits a wide range of ages. Worth a scouting lap when you arrive so each member of your group knows where their favorite area is before lines start to build.
