Litla Dimun is a small island between the islands of Suouroy and Stora Dimun in the Faroe Islands. It is the smallest of the main 18 islands, being less than 100 hectares (250 acres) in area, and is the only uninhabited one.
The southern third of the island is sheer cliff, with the rest rising to the mountain of Slættirnir, which reaches 414 metres (1,358 ft). The island is only inhabited by feral sheep and seabirds. Getting ashore is difficult, and can be performed only in perfect weather. The cliffs can be climbed with the aid of ropes placed by the owners of the sheep.
Clouds often cover the island and thick snow can also be seen on it during winters.
