We visited the watersides, but not the campground. The slides didn't look like much but were more fun than they appeared! There are 2 small slides for the really little kids and 3 slides for the bigger kids. We saw lots of youngsters enjoying themselves (from ages 5 to about 15). The cost was $18 for adults and around $10 for the kids, and it is a full afternoon of entertainment. There is a concession stand, change rooms/washrooms and a warm shower if you need a warm-up during your stay. The grassy area and couple of picnic tables allow for bringing your own lunch and relaxing.
There is a ramp up to the top of the slides (no stairs). It is a relaxed atmosphere - almost as if you are visiting someone's backyard pool. Just way more fun!
