Possidi Cape (Faros) beach in Possidi is actually a sandbar that stretches deep into the sea. It’s a really interesting part of the coast, a miniature sandy peninsula which changes its shape depending on the sea current. Vehicles are parked at the beginning of the sandbar, in the vicinity of the camp and the famous lighthouse, and then the journey continues on foot. The beach is not organized. There are neither beach bars nor sunbeds, so it is essential that you bring food, water and umbrellas. It often happens that on the one hand (toward Posidi) the weather is windy, and on the other (towards Aigeopelagitika) the weather is very calm.
