Short, lively canyon with natural slides, jumps and a famous ‘Mailbox’ rock arch. Guided sessions near Annecy introduce canyoning techniques in a limestone gorge fed by alpine springs.
A cool spray greets you before the first step — the canyon mouth frames a ribbon of water cutting through pale limestone, fir needles slicking the banks. Guides in wetsuits knot harnesses and laugh as participants line up to slip under the rock known locally as “La Boîte aux Lettres” — the Mailbox — a narrow natural arch that sends you through like a letter in motion.

A cool spray greets you before the first step — the canyon mouth frames a ribbon of water cutting through pale limestone, fir needles slicking the banks. Guides in wetsuits knot harnesses and laugh as participants line up to slip under the rock known locally as “La Boîte aux Lettres” — the Mailbox — a narrow natural arch that sends you through like a letter in motion.
This short canyon is classic Haute‑Savoie: a karst corridor carved by meltwater, its pools fed from alpine springs and its channels shaped during the last Ice Age. The route combines small abseils, natural slides and controlled jumps, set against forested slopes that echo centuries of mountain grazing and small lakeside hamlets.
Culturally the area is quiet outdoorsmanship — families and local guides have run canyoning here for decades, using sustainable routes that avoid fragile rock faces. Geologically, the limestone shelves show fossil traces and solution pockets where water has sculpted pockets and slides.
Expect a compact, high‑adrenaline outing: the activity runs roughly 2–3 hours with around 30–60 minutes of active canyoning, led by a guide who provides wetsuit, helmet and harness. You’ll move over mixed terrain — shallow pools, rocky ledges and small rappels — so good footing and basic swimming comfort are required. Bring swimwear, a towel, sturdy water shoes and a lightweight change of clothes. The guide will brief safety, demonstrate rope techniques and set lines for abseils. Weather and water levels control access — mornings often offer calmer flows and clearer pools. For first‑timers this is an accessible, well‑supervised introduction to canyoning in the Annecy basin.
moderate.
2–3 hours.
Moderate fitness; comfortable with uneven terrain and basic swimming for short stretches
The full activity lasts about 2–3 hours with roughly 30–60 minutes spent in the canyon itself.
No prior canyoning experience is required — guides brief techniques and manage rope work; you should be comfortable in water.
Participants must meet age and weight requirements supplied at booking; the activity is not recommended for pregnant travelers or those with significant heart problems.
Tours can be canceled if water levels are unsafe or in severe weather; operators typically notify guests in advance and follow strict safety rules.
The canyon sits in limestone sculpted by glacial melt; local hamlets around Lake Annecy have a long tradition of mountain guiding and summer pasture use.
Operators limit group sizes and stick to established lines to minimize erosion; pack out waste and avoid climbing off-route to protect fragile limestone and riparian plants.
