The river changes quickly with weather and flow, so a local guide is the practical default.
Pozzo del Posse 1 is a Verzasca river dive built around clear water, polished stone, and a controlled current route near Lavertezzo. The dive is about using lines and markers to manage the exit and keep the movement calm through the basin, with bullheads, trout, and other river life in the flow. It works best with a local guide who can choose a day when the water level is workable and the river feels stable.

Community notes to help plan your visit.
Scuba Diving
Expect a guided current dive with a rope and exit markers rather than a freeform drift. The route is about staying composed and reading the basin.
Freediving
Not a freedive-first site; the current and route setup are better suited to scuba.
Snorkeling
Not a snorkel site; the river route is set up for scuba control and a planned exit.
