Dive-site story
Located along the southern shores of Lake Zug near Arth, Egg provides freshwater shore diving across a series of slopes, muddy shelves, and clay drop-offs. Submerged tree roots and fallen branches shelter resident lake fish, while deeper sections plunge steeply toward the lake floor. Cold conditions and silt-sensitive bottom composition require precise buoyancy control throughout the dive.
Steep clay walls and mud formations descending into deep lake waters
Submerged wood structures providing shelter for freshwater predatory fish
High winter water clarity compared to warmer algae-prone months
