Thun

Thun is an inland Swiss town set on Lake Thun, not a marine diving destination. Regional diving activity here focuses on freshwater diving in the lake and related water-body access. Within the Bern region, divers typically encounter clear Alpine waters, varying visibility, and the challenges of freshwater sites such as submerged structures, rocky shores, and lake habitats. Access is convenient from Bern and other nearby towns, with limited offshore or oceanic diving given Switzerland’s landlocked position.
