Dive Site Overview

Diving at Stone Island immerses you in a captivating sunken forest on the south shore of Weissensee, offering a truly unique freshwater experience. Access to this distinct site is facilitated by a regular dive shuttle, which transports divers deep into the nature park, journeying alongside a peaceful mountain stream.

The underwater landscape here is dominated by vast submerged tree roots, creating an intricate, ethereal environment to explore. Exploring the site's three distinct bays reveals beautiful natural light effects, filtering through the interwoven, undercut root systems and the dense, pike-rich reeds that line sections of the bottom.

Beneath the overarching submerged trees, numerous large Chub (Eitel) often gather, basking in the diffused sunlight, presenting excellent photo opportunities. Curious Perch commonly accompany divers through this serene, weightless environment, adding to the interactive experience.

Maximum depth reaches 24 m (79 ft), making it a relaxed dive suitable for a wide range of skill levels, from those completing their Open Water Diver certification to experienced underwater photographers. This location is particularly well-regarded for its visual appeal and tranquil ambiance, providing a striking contrast to typical marine dives.

Careful buoyancy control is key to navigating the delicate root structures and avoiding stirring the silty bottom, preserving visibility for all.

Dive Experience & Conditions

Upon descending into Stone Island's waters, divers immediately notice the unique environment created by the submerged forest. Visibility varies but allows for appreciation of the intricate root systems and plant life. Natural light filters down through the surface, creating dynamic effects as it dances through the branches and reflections off the silty bottom. Operating in a freshwater lake, conditions are characterized by distinct thermal layers, or thermoclines, which can cause significant temperature changes during a single dive. Exploring the maximum depth of 24 m (79 ft) involves navigating through these layers, often feeling cooler water at deeper sections. Currents are generally minimal, allowing for leisurely exploration of the underwater structure.

Dive Difficulty & Safety Guidelines

Expert divers recommend focusing on precise buoyancy control when navigating the intricate network of submerged tree roots at Stone Island. This precaution helps protect both the fragile underwater ecosystem and prevents accidental entanglement. As the site is a popular training ground for Open Water Diver courses, beginners should always dive under the direct supervision of a certified instructor. A daily dive shuttle to the site on Weissensee's south shore streamlines access and enhances overall safety. Divers should be mindful of the freshwater environment and potential colder temperatures, even in shallower sections, ensuring adequate thermal protection.
