Dive Site Characteristics
Dive Site Overview
Exploring Ermitage provides a captivating glimpse into Lake Zurich's depths, blending natural contours with deliberate submerged features. Access to the water is typically from the gravel beach, navigating past a wooden bridge towards Zurich.
Descending, divers first encounter a wall around 10 m (33 ft), which then stretches into deeper sections. Recreational divers can explore several points of interest in the shallower to mid-depths. A nativity scene, old diving tower, and poles are located at approximately 15 meters.
Further details include a raft at about 8.5 meters and a diving bottle near 9 meters, all found to the right of the harbor. For more experienced divers, the site's slope eventually gives way to a partly overhanging steep wall starting around 30 m (100 ft).
This deeper wall can be followed towards the right, leading towards Pfäffikon SZ. Other objects, such as a model skeleton at 32 meters and a treasure chest at 36 meters, are found by following the wall towards Rapperswil (south-east).
Best Time to Dive
Choosing the optimal time to dive Ermitage largely depends on comfort with surface conditions, as underwater temperatures fluctuate seasonally. During summer months, notably July and August, average air temperatures are at their warmest, ranging from 19.4-20.2°C (66.9-68.4°F). This period provides the most pleasant conditions on the surface, despite precipitation averages being slightly higher in July at 5.6 mm. Conversely, winter months like January and February bring significantly colder air, averaging 0.9-4.1°C (33.6-39.4°F), often accompanied by higher wind speeds. For divers seeking milder weather, the spring and autumn shoulder seasons offer a balance; April air temperatures average 9.1°C (48.4°F) with modest rain at 3.8 mm, while September sees average air temperatures of 15.9°C (60.6°F) with similar rainfall. All months generally maintain a 'Good' dive score.

Dive Experience & Conditions
Upon entering the water at Ermitage via the gravel beach, divers typically swim past the wooden bridge towards Zurich. A shallow platform at approximately 2 meters provides an initial staging point. Following the shoreline, a distinct seagrass border often runs at about 5 m (16 ft). Descending further, divers encounter the first wall around 10 meters, which continues its drop to nearly 20 meters. For those venturing deeper, a significant change occurs around 30 meters, where the slope transitions into a steep, sometimes overhanging, wall. This deeper section features a sludge ground before hitting the wall, which can be followed to the right. Navigation for deeper dives might involve following this wall towards Pfäffikon SZ. Overall visibility varies depending on recent weather and surface activity.
Dive Difficulty & Safety Guidelines
Approaching Ermitage requires awareness of its particular underwater topography and cold water environment. Proper dive planning is essential, especially given the site's depths and steep walls. It's not advisable to use the private landing stage belonging to the hotel for entry; instead, divers should utilize the gravel beach. For exits, a landing stage directly in front of the parking lot on the left side of the lawn is the simplest option. Navigation can be complex with the described walls and submerged objects, so careful attention to dive computers and depth limits is crucial. In case of an emergency, the local emergency phone number 144 should be contacted, specifically mentioning a diving accident and requesting Rega. Consider the seasonal closures of public toilets during winter months.
