Regular cache placed on an island approx in the middle of Shiroka Polyana dam.
You will need kind of a boat in order to get on the island. Don't try to reach it by swimming or walking - the island is not that close to the shore and this could be dangerous even in low water. Also never try walking on the iced dam during winter.
Happy hunting and enjoy the Rodhopes.
Shiroka Polyana (Широка поляна) is a reservoir lake situated in the Western Rhodopes mountains in Bulgaria.
The lake is situated 30 km south of Batak, on the road to Dospat. It is located 1500 meters above sea level amidst a forest of old pine trees. Different legends are told about the lake. The shape of Shiroka Poliana reservoir is unique. Viewed from the ring-road it seems that the lake is composed of numerous small lakes with separate walls. This illusion is due to the indented relief of the lake bed that consists of several mountain gullies.Although the banks of the lake are far from the road and comparatively hard to access, it attracts many visitors and sports fishermen because of the abundance of fish, including grey mullet, European perch, and trout.
