A beautiful beach with crystal clear water and soft golden sand. No pebbles or rocks on the shore but there are rocks in the sea a little way out, which are for good snorkeling as we saw quite a few fish. My favourite beach in Rhodes from the ones I saw. In October half term the beach was very quiet but I imagine in peak season it could get crowded. Sun beds are all chargeable but there are limited spaces where you can lay out your towel. There are a few restaurants.
Wonderful sandy beach. A bit dirty. The sea here is dynamic, the water does not freeze like in a quiet bay, sometimes there are amazing waves. By evening the wind usually, but not always, becomes stronger. The sand is quite sticky. Unique cabanas with a view inside the cabana from the parking lot :-) The pile of garbage on the beach, which never gets cleaned (during my stay). Sunbeds, as I understood from other comments, are for a fee, but it is not clear where and to whom to pay. Not overcrowded (in June). There are showers. In general, Pefki beach is a good sandy beach with everything needed.
