Sail Rock is a natural sandstone monolith located on the shore of the Black Sea, in Krasnodar Krai, Russia. It resembles the outline of a ship’s sail, hence its name. The monolith lies 17 km (10.5mi) to the southeast of Gelendzhik, near the village of Praskoveyevka (which is about 500 meters (1,650ft) from the coast) and the farmstead of Dzhankhot (approximately twice that distance from the coast).
