Agios Ioannis is considered being the most beautiful beach on the island’s south-west coast. It is a narrow, perfect for swimming and snorkeling beach and it is usually quieter and less crowded than the other major beaches on the island. It has soft sand and crystalline blue waters. From there, the visitors can enjoy an amazing view over the island of Delos. The beach is partly with umbrellas and sunbeds and partly without so you can choose.
