My family was on our way to Priest Lake, when our RV broke down. We spent an evening at this great water park. Recommend it! Here’s some more great feedback:

Newer amazing water park with heated pools, Large twisty water slide, kids splash pad, toys, fenced off eating area with concessions, clean shower rooms, sunbathing grassy picnic area, next to the City Park. The big pool is 10' deep with a diving board the little one only 3' deep and the toddler splash area is wonderful. -Cory B.

Silverwood is the one Idaho entry...but we're including it because it's so great! I could spend hours and hours in their fun wave pool. The food, the train & the rollercoasters are great too! Here's some more feedback:

We love Silverwood! After going to Disneyland and blowing sooo much money to stand in lines all day, we were blown away by Silverwood! It’s clean, roomy, affordable, and lines are nothing! Plus, best of both worlds with the amusement park and the water park! -Ericka

Amazing! Though it’s a bit smaller than we might be used to in large cities we had a blast at this park. Slides were fun and the lines weren’t long at all. Everyone had a great time and we found the value to be great too! -Rahoolio
