Petit-Saint-Bernard pass and La Thuile

From Les Arcs, it’s a precise 38 km along the D1090 via Bourg‑Saint‑Maurice and Séez to the Petit‑Saint‑Bernard pass at 2,188 m, where waters split toward the Isère and the Aosta Valley. Broad switchbacks climb opposite Mont Pourri and old glacial slabs, then the Roman remains near the stone circle and a 19th‑century statue of Saint Bernard come into view, just before the ancient hospice. Two kilometers away, the Chanousia alpine garden, founded in 1897 by Abbé Chanoux, showcases high‑altitude species. After that, a 12‑km drop carries you into La Thuile for an espresso or tagliatelle alla valdostana.

Your day stays effortless: hotel pick‑up in Les Arcs, Mercedes on standby, and flexible photo stops while your driver handles the road. Our private chauffeur in Les Arcs manages openings at the garden, the border timing, and parking, so you can tour the hospice, taste AOP fontina, and wander Via Marcello Collomb in La Thuile. Return the same way or, if skies are clear, add the Roc Noir viewpoint, with dedicated time to read the glacial landscape and the Celtic‑era stone circle.
