Lake Parz, Forest lake in Dilijan National Park, Armenia

Lake Parz lies at 1,334 m in a shallow valley between wooded hills inside Dilijan National Park, east of Dilijan. It has an elongated outline, about 385 m long and 85 m wide, with a surface of 0.03 km² and a volume of 0.00008 km³. The water is fed by springs and flows through; its depth exceeds 5 m.

The sources describe Lake Parz as a landslide-dammed lake, formed when a slope movement blocked the drainage in its shallow valley; landslide processes remain active around it. It lies at 1,334–1,350 m in the Dilijan National Park area, 9 km northeast of Dilijan, and is fed by springs, with an outflow stream. Its Armenian name means "clear" or "transparent" lake.

The name Պարզ լիճ (Parz Lich) means "clear" or "transparent lake" in Armenian, and Russian sources also record the forms Parzlich and Parz Lich. The lake lies inside Dilijan National Park, east of Dilijan, in a shallow valley between wooded ridges.

The lake lies 9 km northeast of Dilijan at about 1,334–1,350 m, inside Dilijan National Park, reached by a road from the town. The shore is ringed by forest, and the slopes around it are prone to landslides, so stay on marked paths. Fed by springs, the water flows through, and the lake is about 300–385 m long and 85–100 m wide.

Lake Parz formed when a landslide blocked the valley, and landslide processes are still active around its slopes. The lake lies at 1,350 m in Tavush Region, 9 km northeast of Dilijan, and is fed by springs rather than a surface inflow.
