[1] The island has approximately 100 holiday homes and five permanent residences.

[citation needed] Edholma has no road connection to the mainland or other islands.

It is served throughout the year by passenger ships of the Waxholmsbolaget, which call at a pier on the eastern end of the island, providing a connection to Vaxholm town and Stockholm city.

Because of the island's proximity to the Kodjupet strait, which at the time was the main route from the sea to Stockholm, Edholma was fortified from the end of the 19th century to the beginning of the 20th century.

Since 1908 the island has been developed with summer houses, and the farm area was divided up for the same purpose at the end of the 1950.
