Most ski resorts you look at. Les Arcs, in the French Alps, you can actually read — if someone shows you how. A guided tour called Archi Ski takes skiers gently around the resort's different stations while explaining why the buildings look the way they do, and it turns out almost nothing here is accidental.

The tour's central figure is Charlotte Perriand, the designer who led Les Arcs' construction for over two decades starting in 1967. Her brief was harmony: buildings should sit within the mountain rather than dominate it. The effect can be genuinely startling. On the La Cachette chairlift above Arc 1600, a guide points out the large Résidence La Cascade right next to the piste — then, minutes later, the building has vanished into trees and slopes, visible only if you know where to look. Flat roofs were part of the trick, letting snow-covered structures blend with the terrain.

Perriand's other obsession was light. Because Les Arcs 1800 sits deep in the mountains and gets little direct winter sun, buildings that all faced one way would have left many apartments in permanent shadow. So she angled and curved facades to give every apartment a mountain view and sunlight in every window, even on the shortest days. Once you know this, the resort's swooping forms stop looking like architectural whimsy and start looking like solar engineering.

The tour also uncovers a more human backstory. Scattered around are around 15 surviving 18th-century Savoyard chalets, used only in summer because of the cold. And on the edge of Arc 1600 sit the Chalets Pointus, star-shaped, A-frame wooden cottages designed in 1970 by Bernard Taillerfer, a carpenter-architect on Perriand's team. These were built for resort staff and locals who wanted homes outside Perriand's planned vision — not tourists at all until recently. In an irony the egalitarian Perriand probably wouldn't have enjoyed, many are now holiday lets.

The resort itself traces back to Robert Blanc, a local shepherd, mountain guide and ski instructor who dreamed of turning the high pastures of the Tarentaise valley into a modern ski destination — and who recruited Perriand to do it without wrecking the landscape.

Who is this for? Honestly, almost anyone. The route uses beginner-friendly cat tracks and gentle traverses rather than demanding terrain, so it works for mixed-ability groups, families, or anyone wanting a rest day that isn't a wasted day. If you've ever skied a purpose-built French resort and found it a bit brutalist and anonymous, this is the antidote — Les Arcs is the exception that proves design-with-nature was possible, and a few hours with a guide makes the whole place click.
