Dive Site Characteristics
Key Dive Site Facts
Dive Site Overview
Blindsee stands out as a unique freshwater dive site, primarily defined by its remarkable underwater topography. The lake floor features a dramatic submerged forest, where countless tree trunks emerge from the sediment, creating what divers often call a 'Mikado forest.' This intricate network of upright and fallen trees forms a captivating labyrinth, offering a distinct environment for exploration and photography.
The underwater scenery varies, transitioning from these dense tree formations to a gently sloping sediment heap, which contributes to the diverse terrain. Beyond its natural allure, Blindsee provides excellent infrastructure for divers; three purpose-built training platforms are strategically placed at different depths. These platforms are a key resource, widely used for certifications and specialized training, from buoyancy workshops to dry suit orientation.
Divers exploring here can reach depths up to 25 m / 82 ft, although many of the most compelling features of the submerged forest are found in shallower sections. This alpine lake, set against the stunning backdrop of the Austrian Alps, offers a memorable European freshwater diving experience, blending natural wonder with practical training opportunities.
