Devil's Pool is adjacent to the famous Livingstone Island situated on the edge of the Victoria Falls.
Guests can choose to enjoy an exhilarating swim to the edge of the falls during their Livingstone Island visit.
The Devil's Pool is usually open between mid August and mid January - depending on Zambezi water levels.
The Devil's Pool experience is only possible when the water levels are low enough. The dry season usually lasts from September to December in this part of the world.
The local operators will know when it's safe to go, so e-mail them (see above), or have your travel agent check into it for you. During the dry-season the Victoria Falls are actually more spectacular to look at from the Zimbabwean side so you may be based there, but crossing the border is easily arranged.
Jumping into Devil's Pool is an adventurous thing to do and you need to be a decent swimmer. If you're careful it's safe enough and there have been no casualties. There is a safety line to hold onto when you're swimming to get to Devils' Pool in case the current is too much for you.
I had to make a grab for it because I got too cocky and misjudged the strength of the current. Victoria Falls is home to bungee jumping, gorge-swinging, white-water rafting and every extreme sport you can imagine, this is not a "hold-your-hand" environment.
