20 kilometers away from the Alamut Castle is where the beautiful Ovān Lake is located. This small lake has become popular among camping fans and nature lovers in recent years. Located at a high altitude, the lake and its region can get extremely cold in the winter and parts of the lake get frozen. In summer, the pleasant weather attracts many visitors to the lake. There are a few restaurants with basic meals and a couple of guest houses in the surrounding area of Ovan Lake.
