The lifeguard will be happy to escort you on a tour upstream to show the cave and additional, smaller cascades beyond the main falls. I so want to do this at least once. But I know me…I’m braver when it comes to moving on dry land. But I’m going to bring my heavy, duty watershoes, underwater camera and wear my it’s-okay-to-get-wet-hair next time just in case I talk myself into the experience.
