Best for technical divers, 30-85m, boat entry.
Poncione is a technical freshwater dive site in the Verzasca Valley, defined by a steep drop-off that descends from 30 to 85 metres. This site is strictly for experienced divers capable of managing decompression obligations and nitrogen narcosis. Visibility is limited to approximately 5 metres, necessitating excellent buoyancy control and the use of primary and backup lights to navigate the structure. Water temperatures vary significantly with depth and season, requiring appropriate thermal protection. Boat access is mandatory for this location, and divers should be prepared for cold water conditions. Given the depth and technical nature of the site, advanced gas planning and rebreather or trimix capability are strongly advised.
