Isola Licosa is a small island located on the Cilento Coast in the region of Campania, Southern Italy. This small island has a lighthouse and around it, you can enjoy one of the best waters in the entire coast.
I recommend renting a boat in the town of San Marco and then head to Isola Licosa. You can spend all day here to enjoy its stunning crystal clear waters. It's one of my favourite things to do here and I do this every summer.
You can also swim to Licosa, have a walk on the little island and see the lighthouse from up close.
