Freshwater quarry near Angers with training platforms.
Freshwater quarry near Angers with training platforms.
Bécon-les-Granits is a freshwater quarry dive site near Angers with layered plateaus, gangways, and deeper walls that make it a strong training ground. The quarry is used for deep-water practice, reduced-visibility work, and technical sessions, while the shallower shelves and freshwater fish life keep it interesting for slower, more relaxed dives.
Conservative baseline from public research. No community dives logged yet.
Depth range, seasonality, and planning context.
Reported Depth
3m - 50m
Depth Note
The quarry is arranged with shallow platforms and gangways before dropping to a 50 m maximum, so it supports both intro and deep training profiles.
Best Season
Year-round; winter is still workable because the granite holds summer heat.
Typical Conditions
Freshwater quarry with deep platforms, walls, wrecks, and visibility that can swing sharply. Best treated as a controlled training site.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes

Community notes to help plan your visit.
Scuba Diving
Deep-water, reduced-visibility, and XR training are the core use cases, with platforms and plateaus for staged profiles.
Freediving
Freediving is limited to the shallowest controlled areas and is not the quarry's primary use.
Snorkeling
Not a strong snorkel site; the interest is underwater and the quarry is set up around submerged training terrain.
