Big Splash at Arrowhead Resort brings year-round water fun to Alexandria with 38,000 square feet of indoor aquatic entertainment. This isn't your massive destination water park, but it's exactly what families with younger kids are looking for. The centerpiece is a multi-level play structure loaded with water features, tipping buckets, and smaller slides that keep children entertained for hours. You'll find a good-sized pool for swimming and playing, plus a lazy river that's perfect for floating around when you need a break from chasing the kids. The water slides here are designed more for fun than fear - think family-friendly tube slides and body slides that get your heart pumping without terrifying anyone. The splash pad area is great for toddlers who aren't ready for the bigger attractions yet. What really sets Big Splash apart is the resort connection. You can book a room at Arrowhead Resort and have the water park right there, which makes it incredibly convenient for families doing a Minnesota lakes vacation. The facility stays comfortably warm year-round, so it's a solid winter destination when you're tired of snow. The space feels intimate rather than overwhelming, and parents can actually keep track of their kids without feeling like they need a search party. Food options are limited to basic snacks and drinks, so consider eating before you arrive or plan to head back to your room. The locker and changing room setup is straightforward, though arriving early on weekends gives you better access to seating areas. This place works best for families with kids under 12 who want a fun, manageable water park experience without the chaos of the mega-parks. It's also perfect for a quick getaway when you need to escape cold Minnesota winters.

Best time to go
Resort water parks are quietest mid-week and during the second half of any school break. Many resorts open the water park to overnight guests an hour before day-pass holders, so a one-night stay is often worth the math vs. two day passes.
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
Big Splash at Arrowhead Resort sits in Alexandria, 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.
