As soon as we could swim, we went to the two caves on the far side. There was a ledge at the back of both caves and we sat there nearly up to our heads remember we were shorter then. The caves were connected by an underwater connection. I don't think that you can use them today, seems they were too dangerous. The high dive is now a waterfall. When I was a teenager a diver hit a friend head to head, and both received concussions.
Check to see that converted high dive.
