Baumgärtli, located on Lake Zug in Switzerland, is a popular shore-accessible dive site suitable for both beginners and experienced divers. Entry and exit are via a stone staircase, which can be slippery due to algae, so caution is advised. Paid parking is available directly at the entrance, but there are no restroom facilities on site.
From the entry point, divers can head approximately 10 to 50 meters to the right towards Immensee. The initial descent follows the coastline to a gravel shoal, where it's worth exploring beneath the rocks for hidden life. Continuing further right, a pipe anchored in the rock between 0 and 3.5 meters marks the beginning of a substantial, often stepped wall. This wall descends significantly, reaching well below 40 meters, and features numerous crevices and holes that are often occupied by fish. The left side of the wall also offers an area suitable for introductory diving exercises.
Baumgärtli boasts an abundant freshwater marine life population, observable year-round. Divers frequently encounter eglis (perch/flounder), burbot (Trüschen/Quappen), sunfish, pike, and crayfish (Kamberkrebse), making it an excellent spot for fish identification and macro observation. While enjoyable diving conditions prevail most of the year, be mindful of the cool water temperatures typical of Swiss lakes. Freedivers and snorkelers will also find the site appealing due to its accessibility and suitable average depths. Divers should exercise caution in poor visibility, as fallen branches can pose a snagging hazard.
