Weesen Tunnel 1
Steep Walensee wall dive by Betlis' first tunnel.
Plan for a slippery shore entry, timed road access, and an immediate drop into cold lake water with deep walls.
About Weesen Tunnel 1
Weesen Tunnel 1 is a Walensee wall dive in Betlis with a steep shore entry just after the first tunnel. The route drops quickly into deep freshwater rock walls, so the dive is shaped by depth control and a careful return rather than by a long swim. Access is straightforward on paper but the path is slippery, the road has timed traffic windows, and parking is limited near the shoreline. Expect cold, clear lake water and a classic Swiss wall feel rather than a relaxed beach entry.
