Private winter lake dive with trout and submerged trees.
Private winter lake dive with trout and submerged trees.
Blausee is a private mountain-lake dive in the Bernese Oberland that is only open in winter. Divers explore a short, relaxed circuit through clear cold water, passing submerged trees, large boulders, and a famous stone sculpture while hundreds of organic trout move through the lake. Because access is by appointment and the dive is limited to certified divers, it feels more like a curated winter outing than an everyday shore dive.
