Best for technical divers, 42-67m, shore entry, moderate current.
The Hirondelle is a technical wreck dive located in Lake Geneva, resting at depths between 42 and 67 metres. This freshwater site requires advanced planning due to the significant depth, cold water temperatures, and moderate currents. Divers should expect visibility of approximately 5 metres, necessitating close-quarters navigation of the structure. Shore entry is available, though the dive demands strict adherence to decompression protocols and careful gas management to mitigate risks associated with nitrogen narcosis and the challenging environment. Given the technical nature of the site, divers must maintain team discipline and carry a surface marker buoy throughout the dive.

Given the low visibility and decompression obligation, carry a surface marker buoy and ensure your team has agreed on gas turn pressures before the dive. Conditions can shift, so check with local dive operators for current water temperature and any seasonal current patterns before committing to the site.
