💬 What Visitors Say

🕐Arrive after 11 AM when the kids' area fully activates, and plan to spend 2-3 hours for a satisfying visit. The facility gets busy on weekends, so weekday visits may offer a more relaxed experience.
💬Water temperatures vary by area—the wave pool is warmest, while other slides and pools run cold. Bring extra towels and plan to use the large hot tub to warm up, especially for younger children who are more sensitive to cold water.
💬If you're a hotel guest at Big Horn Resort, ask about discounted admission rates. The annual family pass at $425 for up to 4 members offers good value for frequent visitors, and kids 3 and under are free.
💬Call ahead before visiting to confirm all water slides and activity pools are operational, as maintenance issues can limit available attractions. The locker kiosk and food service may occasionally be unavailable, so arrive prepared.
💡For birthday parties, contact the venue early through phone or Facebook, but be aware communication can be slow. Have backup event plans ready and allow extra time for responses when booking.
