Lysekil's world-class marine research aquarium, set in the Gullmarn Fjord — Sweden's only true fjord — opens its labs and holding tanks exclusively to small groups for an intimate dive into Nordic marine science.
What to expect
A marine biologist leads you through tanks showcasing the full Gullmarn ecosystem: spiny lobsters, wolf-fish, electric rays, and vast shoals of Atlantic herring that pulse like living silver curtains. The researcher explains the fjord's unique halocline — a sharp boundary between saltwater layers — and ongoing conservation projects. Children and adults alike are transfixed by the touch pools and the tunnel walkway beneath the main tank. The facility sits directly on the waterfront, a pleasant 10-minute stroll from the cruise quay.
Good to know
Pre-book the private guided tour directly via the Havets Hus website; standard entry alone does not include the guide or lab access. Allow 2 hours. Opens 10:00; confirm seasonal hours when booking.
