Everything you need to know about this dive site.
Dive Site Overview
Släggö has long held a reputation as Sweden's most popular dive site, a distinction it earns through its accessible setup and diverse underwater landscape. Positioned precisely at the mouth of Sweden's sole threshold fjord, the site benefits from a rich marine ecosystem where marine life thrives.
Divers typically begin their descent on a gently sloping bottom, which gradually leads towards an impressive wall, often described as a "wall of mystique and lobster joy." This primary feature, consistent with its "wall" tag, provides easy navigation for divers. By staying near the wall, individuals can comfortably manage their depth while exploring various rock formations, boulder fields ("stenrösen"), and the occasional wreck found in deeper sections.
The maximum depth is reported at 31.2 m (102 ft), though many recreational dives average around 16 m (52 ft). The site's enduring popularity is also rooted in the variety of encounters it provides for divers of different skill levels, from beginners on the slope to more experienced divers exploring the wall's deeper crevices.
Its convenient access, including nearby parking, contributes significantly to its appeal, allowing for straightforward shore entries and exits, which is a key factor in its high visitation rate.
