The second and more secluded place for getting your thrills on Capri, is on the south side of the island at the Grotto Arsenale. This was an area inhabited by a nudists who lived under some rocks. I'm not kidding. But, we decided they were probably harmless, so we commenced our aerial water contest with much success! Even got a few claps from the audience.
Unlike the Grotto Azure, you will not have to wait for tour boats, and you won't have many people around. Great place.
There are a few spots on Capri that allow for some good cliff jumping. My friends and I took full advantage of this! The best place is at the walkway that leads down to the Grotto Azure. There is about a 10 meter high concrete platform that you can easily climb onto. The water is deep enough!! I'm still here!
Please note that this can only be done after 4:30 PM when the tour boats stop taking people inside.
