Seven Clans Casino Thief River Falls is the Red Lake Nation's largest property, and the reason most guests book it has nothing to do with gambling. It rates 3.6 from more than 1,800 Google reviewers.
The casino was built in the early 1990s as River Road Casino. The hotel and the waterpark were completed in 2001, and the property took its current name then. If you find references to River Road, that is this place.
The waterpark
This is the property, functionally speaking.
The indoor waterpark covers 40,000 square feet and was renovated in 2019. It carries four large water slides and several mini-slides, two hot tubs, a lazy river, a shallow wading pool, a swimming pool and balcony seating, with a toddler area and splash pad.
It is the only waterpark of its size for hours in any direction in north-western Minnesota — a genuinely significant thing in a region where winter runs from November to April and there is nowhere else to take children.
The honest reading of the property's 3.6 rating is that a lot of it comes from families reviewing a hotel and waterpark rather than gamblers reviewing a casino, and family reviews of a busy waterpark are a tough crowd.
What's on the floor
654 slot machines and four live blackjack tables.
Four tables is a small pit, and they run on a schedule rather than continuously — check the venue's site before planning around blackjack specifically. Video gaming options fill in around them.
This is not a floor anyone travels for. It is a floor that exists because the hotel and waterpark bring people to the building.
Hotel and amenities
The hotel runs 151 rooms, and the complex adds an arcade and event space alongside the casino and waterpark.
Tips before you go
The casino is open 24 hours, seven days a week. The waterpark keeps its own hours and requires a wristband — confirm the schedule when booking rather than assuming it runs all day.
Minnesota tribal casinos generally admit players from 18, though individual properties set their own rules and areas serving alcohol are often 21-plus. Confirm with the venue before travelling.
Book well ahead for school holidays and long weekends in winter. The waterpark is the regional draw and 151 rooms is not much inventory against it.
