Sweden's marine national park: cool-water diving, interpreted snorkel trails and island life
Pick an activity mode to compare signature sites, skill fit, and gear planning notes before you lock your trip.
Stromstad and Sydkoster are local-dive staging points rather than liveaboard ports. Stromstad Sport Diving Club publishes a 2026 excursion page with guest participation prices; Kosterbladet 2026 still lists Trident Divers as a Sydkoster dive centre near the island ferry route. A current retail boat schedule, course availability and dive-site permissions were not independently established. Plan only with an operator who supplies the exact site, conditions and current equipment status.
