In the north there is moorland with four small lakes, of which Fagradalsvatn is the largest.

The island has one settlement, a village also named Hestur on the east coast.

In 1919 a fishing accident resulted in the deaths of one-third of Hestur's men.

In an attempt to fight the depopulation of the village, a swimming pool was built on the island in 1974.

On the southern part of the island by the lake Fagradalsvatn, one can camp.
