Sandoy gets its name from the large beach at Sandur, and the general sandy soil of the island. It is the only island with dunes.
There are similarly named islands, Sanday in the Orkney Islands, Sanday in the Inner Hebrides and Sandøy in Norway.
A proposal has been approved by the Faroese parliament to build a tunnel connecting Sandoy with the more populous Streymoy to the north. Construction is not intended to be completed until 2021.
