Rochers du Saussois

Rochers du Saussois is a band of limestone cliffs rising above the Yonne river in the commune of Merry-sur-Yonne, and one of France's most storied rock-climbing destinations. Walls reaching up to fifty meters tower over the river and surrounding meadows, drawing climbers from across the country for generations.

Where is it and how do you get there?

Le Saussois sits in the Yonne department, roughly thirty kilometers south of Auxerre and about a two-hour drive from Paris. That proximity to the capital earned the cliffs their informal nickname, "the Parisians' crag" — for many climbers from the Île-de-France region, this is the nearest serious limestone climbing available, making it a popular weekend destination. Getting there means driving local roads along the Yonne valley, with parking near the hamlet of Le Saussois, which gave the cliffs their name. From there, a short walk leads to the base of the walls.

What will you see there?

The cliffs are made of compact, occasionally brittle limestone, marked by distinctively small holds — countless one-, two-, and three-finger pockets that reward precise technique over raw strength. The upper sections of many routes overhang, giving the climbing an athletic, powerful character. The site holds around 250 routes graded from 4a to 8c, meaning it welcomes beginners while still offering serious challenges to the most advanced climbers. The walls face predominantly west, catching afternoon sun, and the view from the top over the meandering Yonne and surrounding hills is one of the site's biggest draws — even for visitors who come without climbing gear, just to walk and take in the scenery.

History and climbing significance

Climbing tradition at Le Saussois goes back to before the Second World War — one of its iconic routes, Cheminée de la Martine, saw its first ascent as early as 1939. Since then, the site has become part of French climbing history, with successive generations of climbers establishing new and increasingly difficult routes, cementing Le Saussois's reputation as one of the country's most technically demanding crags.

When should you visit?

The best climbing season runs from March to November. Spring and autumn bring moderate temperatures when the limestone holds good friction and the heat doesn't get in the way on the sun-facing western walls. In summer, it's worth timing sessions for morning or late afternoon to avoid the hottest part of the day.
