Wall climbing is a fun sport and a good way to work those glutes, arms, and abs. But if you're worried about falling, then here's one place you don't have to worry about it. AquaSport's climbing walls are installed on the ede of a pool so if you lose your grip or footing you're just going to splash.
The wall is also color coded, just like how normal walls would be, and the highest you'll be able to get at is 23 feet above the surface of the water.
At $4,500—pre-installation—it's certainly more expensive than a slide. Just make sure your pool is deep enough.
