Mavros Kolympos Beach is one of the most serene destinations in southeastern Crete, located between Ierapetra and Makry Gialos, just east of the Achlia area.

Its name (meaning "Black Pool") is derived from the dark pebbles and black rocks that dominate the landscape, giving the waters a deep, striking blue color.

The beach is characterized by its rugged beauty and pristine, deep waters, which usually remain calm as the bay is sheltered from strong winds. The shore is covered with fine dark pebbles, while the seabed is rich with rocks, making it a paradise for snorkeling enthusiasts and underwater exploration.

Mavros Kolympos is partially organized, maintaining a very quiet character even during the peak tourist season. Along the beach, tamarisk trees offer natural shade, and several traditional tavernas and rental rooms operate nearby. Access is extremely easy via the main road, making it an ideal choice for those seeking seclusion and contact with nature without sacrificing easy access to the amenities of surrounding settlements.
