Akna

Akna is a crater lake sitting inside the extinct Lchayn volcano, on the high plateau of the Gegham mountains at 3,031 meters. It lies right on the line between Kotayk and Gegharkunik provinces, on the slope of Aknasar mountain, about 10 km west of the village of Tsaghkashen.

The lake's surface covers roughly 0.8 square km (some sources give 0.5), with a maximum depth of 15 meters and a volume estimated between 2.5 and 3.9 million cubic meters. Its water drains into the Hrazdan river basin.

Akna was added to Armenia's list of state natural monuments under a government decision dated August 14, 2008.

Akna sits in Kotayk province, on the plateau of the Gegham mountains near the Gegharkunik border and the village of Tsaghkashen, roughly 37 km east-northeast of Yerevan in a straight line.
