Dive Site Overview

Pozzo del Posse 1, a key site within Switzerland's dynamic Verzasca River system, offers a distinctive freshwater diving experience in the Ticino region. Forming one of three principal dive locations along the Verzasca, its character is shaped by a consistent river flow and striking underwater rock formations.

Consistently clear, cold water provides exceptional visibility, often revealing several meters of the sculpted riverbed terrain. Geological features, meticulously carved and smoothed by the river's relentless current over millennia, create a visually compelling landscape of basins, channels, and impressive boulder formations.

Regarded as a drift dive, divers are carried along by the natural current, demanding advanced buoyancy control and precise navigation through the river's "canyon" like structures. Successful excursions here require a competent surface support system and careful planning to ensure a safe, engaging descent through this remarkable, flowing environment.

The experience centers less on typical marine life and more on the raw power and beauty of an alpine river. Divers appreciate the sheer force that shaped this unique underwater world, making it a truly memorable adventure.
