Stóra Dímun is a small island between Sandoy and Suðuroy.
Only one family lives on Stóra Dímun. They live by agriculture with bird catching as a sideline.
The island is difficult to access from the sea and thus has been rather isolated until recently. There is no ferry going to Stóra Dímun but the helicopter visits it 3 times a week. On Wednesdays the helicopter visits the island twice so its possible to enjoy a few hours there and then go back same day.
The highest point on the island is ‘Hogoyggj’ which is 505 meters high.

The Icelandic saga, Faereyingasaga, tells that Beinir and Brestir have a farm on Stóra Dímun. It was here that Sigmundur Brestisson when he was 9 years old watched his father being murdered. Sigmundur later tried to avenge his father's death. He christianised Faroe Islands in the year 1000.
