WOW!!! The view is FANTASTIC, the best in Oia to see the caldera and the Aegean sea. The Cave gives a real feel of authenticity and Santorini. There is access to beach below. Wear closed shoes, it is a rough trek down the rocks. But TOTALLY WORTH IT! Ask for kayak. We took the kayak to the cliff jumping platform, you’ll see and hear them so you’ll know where to go. Nicolleta was so helpful, Rena was so prompt for any questions you may have. I highly highly recommend!!!
