When we got to waterfall #1, the sun was blaring, so I shot mostly video of the falls and of us swimming. This swimming hole slips off sharply into a deep hole - if you slip near the edge you are going under. We got in at the far end of the pool and swam up. Here I could put my feet across to the opposite side and brace myself for the spray. I couldn't touch bottom so have no idea how deep it is.
