Yes, I tried but is freezing!!!!
Yes . Its really cold , but swimming is allowed
The upper falls, I'm not sure you can swim there or not? Deffinately you can swim in the middle falls and lower falls. You can even jump off the edge into the water at the lower falls, and I have jumped off the steep cliff right next to the middle falls into the water, but only after I watched someone else do it. It's scary as heck though!! The water looks all black from the ledge. I would use extreme caution though if you plan on jumping at any of the falls and probably wait til you see someone else do it so you know exactly where to jump in at. Cause I'm sure there are some big boulders under the water!!
U can only near the lower falls but it will be really freezing
