Ameisenecke is a Lake Thun shore wall dive with two canyons, a steep face, and a seaweed-covered shallow plain above the drop. It is an easy shore entry with ramps, but the site quickly turns into a deep freshwater wall dive that rewards good trim, careful buoyancy, and a calm plan for the horseshoe route. Bring a torch if you want to inspect the wall closely and expect to share the ramps with other teams on busier days.
