Gullmarn and Lysekil

At Lysekil, Gullmarsfjorden meets the Skagerrak through a deep sill. Its unusual water exchange supports marine life that researchers and divers study, while the town supplies shore and day-boat diving, training, gear services and welcoming non-diver options. Start with Slaggo near the dive center, then use local guidance for the fjord's walls, mixed bottoms and seasonal boat routes. Havets Hus explains why the fjord is distinctive. On the Skafto side, Fiskebackskil adds shallow interpretive snorkel trails and seaside walks. The most comfortable overall visit is summer, but suitably equipped divers also visit in colder months. The plan is locally based, not a liveaboard itinerary. Gullmarn's protected status does not grant unrestricted access to every shore, harbor or research area; verify current site rules and conditions before entering.
