Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
This dive site on Lake Zug, Egg in Arth, provides a relatively shallow and accessible entry point suitable for various dive plans. From the large parking area between Walchwil and Arth, a path leads directly to the lake.
Divers enter over the stony embankment into flat water, a process considered simple enough for most. The site primarily features two distinct underwater areas: a bay to the left of the entry, which remains quite shallow, and a route to the right, heading north.
Following the rightward path, divers will encounter a small wall at approximately 25 m (82 ft), a known spot for observing burbot.
Notably, the area around the initial entry, between 5-10 m (16-33 ft), has been reported to contain discarded items like strollers, pans, and beverage cans, an observation that frames part of the dive's 'historical' interaction with human activity. Its generally calm nature makes it well-suited for night diving experiences, where the atmosphere shifts dramatically.
This site’s inherent ease of access and dual-area exploration provides a rounded lake diving experience.

Dive Experience & Conditions
The underwater landscape at Egg, Arth starts with a gentle entry over a stony embankment, leading into a relatively flat, shallow bay immediately to the left. This area is generally easy to navigate and ideal for less experienced divers or those getting reacquainted with their gear. Moving right from the entry, towards the north, the depth gradually increases. Divers exploring this direction will find a small wall feature at approximately 25 m (82 ft). This vertical drop-off provides a habitat for different species and a change in topography. The dive site is characterized by an overall depth profile that remains within recreational limits. Due to its lake environment, visibility can vary depending on recent weather and sediment, but it often allows for comfortable observation. Water temperatures are not consistently reported but will be typical for a freshwater lake in Switzerland, requiring suitable exposure protection.
Dive Difficulty & Safety Guidelines
Approaching Egg, Arth requires divers to possess some prior experience, as the site is rated with a medium difficulty. It's not considered an entry-level spot for absolute beginners. Before entering, consulting a local dive professional familiar with Lake Zug's current conditions is always advisable. Divers should be aware of the debris found in the shallower sections (5-10 m / 16-33 ft), which, while not direct hazards, reflect human impact on the environment and require careful buoyancy control to avoid disturbing the bottom. Night diving is a popular activity here, and as such, divers must adhere to standard nocturnal diving protocols, including carrying multiple light sources and maintaining close contact with their buddy. Planning your dive within your certification limits is paramount for a safe experience.
