To get to Sandhamn you sail from the beacon-illuminated route north of Sandön. Shallow-draught boats can even take the KSSS marked route between Telegrafholmen and Lökholmen.
From the route north of Sandön to the south of Lökholmen, there is a speed limit of 5 knots.
On the Sandhamn side there are berths for approx. 180 visiting boats and at the adjacent Lökholmen there are berths for a further 200. On the northern part of the L-shaped pontoon jetty there are places for temporary mooring. The reserved places are marked with signs.
