Hästholmen is an island in the Stockholm archipelago in Sweden. Skogsön island lies to its north-west, Tynningö island to its south-west, and the to its east. Administratively, it is in Vaxholm Municipality and Stockholm County.[1]
Hästholmen has no road connection to the mainland or other islands. It is served from spring to autumn by passenger ships of the Waxholmsbolaget, providing a connection to Vaxholm town and Stockholm city, but there is no service in winter.[1] [2] [3]
This island should not be mistaken for the double-island of Stegesund-Hästholmen, also in Vaxholm Municipality, but situated some to the north-west.[1]
