The Cave of Poetry, also known as Grotta della Poesia, is a famous natural swimming pool near Roca Vecchia. It's actually a little smaller than I had imagined, and I'm glad there's more to this natural area than just this cave.

To get to the cave itself, head just a few meters south of the Santuario della Madonna di Roca Vecchia, where you'll see a sign welcoming you to the Area Archeologica Grotta della Poesia, and you'll have a couple of hundred meters to walk (carefully because it's rocky).

You can swim in the crystal-clear waters, but watch your step on the stone staircase leading to the pool, and bring cash for the small entrance fee (free entry when it's not yet the peak season).

The Cave of Poetry has become an extremely popular spot, especially in the summer, so visit early in the day to beat the crowds.
