Can you skate on frozen above ground pool?

Absolutely yes but please make sure the ice is thick enough and keep your skates away from the tile & coping stones.

To make sure the ice is thick enough look at the colour. if it is nearly Snow White you can skate or another way is to stand at the side of the pool and put one foot on it.

Also, you can get something as heavy as you (or very similar) and slide it on the ice. If it breaks, not good to skate on.
