Linked from the beaches of Agios Giorgios Perissia is the beach of Perivolos, with parasols and deck chairs like the other beach, but the atmosphere is a little less touristy. The beach is huge and there is room for everyone. In Santorini the price is double the other islands like Naxos or Milos, at € 10. It's fun to see entire families running from the towel to the sea to avoid burning their feet on the black sand. Normally blue flag, it can be somewhat murky due to algae. But the experience is worth it. It's one of the best beaches in Santorini.
