It is a marked freshwater parcours with submerged objects.
The Achensee, TCI Parcours is a marked freshwater dive route in Lake Achensee with a line of submerged objects below the tunnel north of Maurach. Divers pass playful installations such as an upside-down boat, a bathtub dive bell, and larger pieces like a lift gondola, so the appeal is the route itself rather than fish life. It is a regulated alpine lake dive that rewards careful navigation, trim, and a warm suit. Expect a sightseeing parcours rather than a reef or wreck experience.
