Roc d'Enfer

Roc d'Enfer is a mountain peak in the commune of Saint-Jean-d'Aulps, in the Haute-Savoie department of France. It rises in the Préalpes de Savoie, part of the Chablais massif, about 20 km south of Lake Geneva and just west of Morzine. The peak has given its name to the domaine skiable Roc d'Enfer, a ski area linking the villages of Saint-Jean-d'Aulps, La Forclaz and Bellevaux — a quieter alternative to the bigger, better-known resorts of the Chablais region.

Where exactly is Roc d'Enfer?

The mountain sits at the meeting point of several Chablais valleys, framed by the villages of Saint-Jean-d'Aulps, La Forclaz and Bellevaux. This is classic Préalpes de Savoie terrain: gentler and more wooded than the high granite ranges around Mont Blanc or the Écrins, but with wide-open views stretching to Lake Geneva and the Swiss peaks across the border.

What will you see here?

The landscape around Roc d'Enfer is textbook Chablais: green valleys, alpine pastures and conifer forest lower down, giving way to rockier ridgelines and viewpoints higher up. In winter the slopes become the domaine skiable Roc d'Enfer, a network of runs connecting the three villages, aimed at families and skiers who prefer a calmer atmosphere than Portes du Soleil or Avoriaz, both in the same corner of the Alps. In summer, the same terrain opens up for hiking and mountain biking, with panoramas over Lake Geneva as a reward for the climb.

How do you get to Roc d'Enfer?

The nearest larger town is Thonon-les-Bains on Lake Geneva, from where local roads lead into Saint-Jean-d'Aulps, La Forclaz and Bellevaux — the three main gateways to the Roc d'Enfer area. The region sits close to Geneva, making it an easy trip from both France and Switzerland; the nearest international airport is Geneva Airport, with the rest of the journey completed by car or local transport into the Chablais valley.

When should you visit?

The winter season, roughly December to April, is when the domaine skiable Roc d'Enfer operates — the time to come for skiing on slopes that stay noticeably less crowded than the region's larger resorts. Summer, from June to September, reveals the other side of the mountain: hiking trails, mountain-bike routes and viewpoints become accessible once the snow clears, with comfortable temperatures for full days outdoors. Spring and autumn are transitional periods, when some tourist infrastructure may be closed.
