Grigoleti Lake

Grigoleti Lake: The Relict Pearl of the Colchis Coast

Grigoleti Lake, located in the Guria region, is a unique natural monument nestled right behind the famous magnetic sand beaches of the Black Sea coast. This is a relict lake, a remnant of an ancient sea bay that was gradually separated from the main body of water by coastal dunes. Surrounded by the lush, humid vegetation of the Colchic wetlands, the lake is a tranquil oasis. Its dark, calm waters reflect the dense alder and peat moss forests that fringe its shores, creating a mystical and slightly primeval atmosphere. Ecologically, it is a vital part of the Kolkheti National Park system, serving as an important habitat for aquatic plants and a resting place for migratory birds. For visitors, Grigoleti Lake offers a different experience from the nearby sea—a quiet retreat for fishing, birdwatching, or simply enjoying the serene beauty of a landscape that has existed since antiquity.
