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 one uninhabited. One of the most striking feature of this island is that it often remains covered in clouds. This type of cloud is known as Lenticular clouds, so called because it is shaped like a lens. Lenticular clouds are always stationary and when formed over mountain peaks or islands, like Litla Dimun, looks like a majestic hat.
The southern third of the island is sheer cliff, with the rest rising to the mountain of Slaettirnir, which reaches 414 metres (1,358 ft). The island has never been inhabited by humans, but sheep were kept there from ancient times, being mentioned in the 13th century work F�reyinga Saga (Saga of the Faroese). Getting ashore is difficult and can only be performed in perfect weather. The cliffs can be climbed with the aid of ropes placed by the owners of the sheep.
