Preveli Beach is a secluded beach found on Crete, located about 43 kilometres from Rethymnon town. But it's more than just a beach -- it's also a river lagoon and a palm forest.
A quick hike will get you down through the palm forest and on the beach, but keep in mind it gets busy during the summer months. It's worth it for the clear waters. Also nearby is the Preveli Monastery.
