Dive-site story
Located along the waterfront in Lysekil at the mouth of Gullmarn fjord, Släggö is one of Sweden's most frequented shore diving sites. Entry steps and railings lead into a sheltered bay with purpose-built underwater training platforms and permanent guideline courses. The seabed transitions from shallow kelp-covered rocks to gently sloping mud flats, giving way to rockier reefs further out that host a surprising variety of Nordic marine life.
Submerged training platforms and permanent compass courses make underwater navigation straightforward.
Convenient shore infrastructure with stairs, railings, and gear benches right at the water's edge.
Productive night diving location where lobsters, crabs, and nudibranchs wander across the muddy bottom.
