Agios Ioannis beach is smaller than that in Sarakiniko but totally unspoilt, with no infrastructure: which means that you have to take care of the necessities for yourself. The water is clear and shallow; here too the beach ends in dunes with cedar trees that offer shade to campers. You should be aware that the beach - indeed the whole island - attracts many nudists.
It is a landscape of incredible natural beauty and that is why the Discovery Channel a few years past voted it as the second best beach in the world.
The name of Agios Ioannis is from the chapel here, around which are found ruins of ancient buildings and water-tanks cut into the ground.
This is located 4 km west of Sarakiniko. To get there you follow the surfaced road until you find the only restaurant in the area, then you continue walking amongst the rocks and sand (and ideally this is why you would not make the trip in the afternoon, when the heat is too strong and the sand burns the feet). The journey from Sarakiniko on foot will take you about 45 minutes. There is also the option to get part the way there by the local bus.
At the west of the beach begins the coastal path that leads to the neighbouring one of Lavrakas.
