Lysiacha Bay, bay and beach in Crimea, Ukraine

Lysiacha Bay is a Black Sea inlet about 4–5 km long between the Kara-Dag and Meganom massifs, below the Echki-Dag ridge. Its cut coastline has plateaus, hills and cliffs with height drops of hundreds of metres. The shore has no buildings, only tents and dirt roads.

In 2007 the Crimean parliament declared the bay and its adjoining land and sea a local landscape reserve, halting a planned 5,000-place resort by the TMM company. In 2008 the reserve was downgraded to a regional landscape park, which permits recreation zones, though the resort was never built. The bay lies between the Kara-Dag and Meganom massifs, below the Echki-Dag ridge.

The bay's name is debated: some link it to the sea fox, while old residents say it was once called "Lysa" (bald) for its bare coastal ledges. Its shore is a well-known nudist beach and a gathering spot for hippies and other nonconformists. In summer, several portable food shops form a small market on the coast.

The bay lies between the Kara-Dag and Meganom massifs, below the Echki-Dag ridge, with only dirt roads and no buildings; access is on foot from the villages of Pribrezhnoye and Kurortnoye. Some descents and paths are steep and dangerous, and being drunk on the climbs poses a direct threat to life. In summer, several portable shops form a small market on the coast.

Grey volcanic clay, called kil, lies in large quantities in the bay and is used for mud baths. The name may come from the bare coastal ledges: old residents say the bay was once called Lysa (bald), not Lisya (fox).
