The devils pool is located in Zambia. It's super tricky to get to and much more dangerous than you'd think. It wouldn't just be discouraged in the USA it would be downright illegal to swim in. The water levels play a big part the higher they are the more dangerous and at high season you can't get near it but there are times when the water is lower than when we were there which one can only assume would've made is safer. It's a special place.
