The Gulen House Reef is the shore dive in front of Gulen Dive Resort and a macro site known among Scandinavian underwater photographers. More than 50 nudibranch species have turned up here in two years, and it draws divers from across Scandinavia for its small and unusual life.

Also known as house reef, Gulen house reef.

The dive

Rare gobies linger in the sand and clingfish guard eggs laid inside empty seashells. In spring squid eggs hang on the kelp, and lobsters, metre-long wolffish and large monkfish visit often. At 30 m and deeper, lucky divers find stone crabs sheltering under the big pink anemones while they wait to moult their spiky carapace.
