When you reach Iraklia’s major ‘sight’, the Cave of the Sacred Icon of Agios Giannis, you ' ll find a large open cave on the left, and to the right, white-painted rocks surrounding the tiny entrance to the main sequence of caves. A torch is useful and the initial scramble along a low-roofed tunnel is worth it, leading as it does to caves full of stalactites and stalagmites.
The cave can be reached on foot from Agios Giorgios in about two hours (one way).
The signed path is along community trails 3, 4 and 7; details are outlined on the Terrain map, along with other island walks. Good walking shoes and water are essential.
On 28 August, the eve of the death of John the Baptist, crowds of local people assemble at the cave and crawl inside the cave to hold a candlelit service.
