The Kapnis Gorge is located between the Imbros and Asfendos Gorge. It is a very wild and spectacular gorge and difficult to access. The gorge is still very unknown and only few people go through. The gorge is quite long and it takes about 4 hours to walk through. It is a difficult and dangerous walk with craggy riverbed which in some places creates dry waterfalls and requires climbing. It is not recommended for people who have no experience with mountaineering. Its entrance is situated on the southern side of the mountains of Akones and at the fourth km of the asphalt road from Imbros to Asfendou in Sfakia, at an altitude of 900 m.
