Cycling in Bourg-d'Oisans is a game of flat valley floor and sudden vertical. You spin along the Romanche on almost level roads, then turn off and climb steeply for an hour or more. There is very little rolling middle ground, so every ride comes down to a warm-up, a long sustained effort and a fast technical descent. A mid-ride café stop is normal practice, usually at a summit or in a village on the way home, and the day is planned around it.

Start with Alpe d'Huez, then work outwards to Col du Glandon and Col de la Croix-de-Fer, and save Col du Galibier and Col de Granon for days when you are ready to travel. Alpe d'Huez begins about 5 km from town, which makes it the obvious first ride. Glandon (HC, 21.0 km at 7.0%) and Croix-de-Fer (14.3 km at 5.8% from Saint-Jean-d'Arves) sit around 23 km away and pair naturally into one big loop. Galibier from Valloire (17.0 km at 6.9%, summit 2642 m) is 30 km out and Granon (11.8 km at 8.9%, HC) is 47 km, so both need an early start or a transfer.

Plan three to four days for the headline climbs, about a week if you want the full set without wrecking yourself. A short stay covers Alpe d'Huez and one big loop over Glandon and Croix-de-Fer. A week lets you add Galibier from Valloire and Granon, both of which involve a drive or a long approach, plus an easy valley day between the hard ones. If you only have a weekend, ride Alpe d'Huez first — it is the climb the base exists for.

Yes — arriving in Bourg-d'Oisans without a bike works perfectly well, since hire is available in town and geared to the local terrain. That makes flying in realistic: the nearest airport, Grenoble Alpes Isère (GNB), is 65 km away, and you can be on a climb the same afternoon without boxing and rebuilding your own machine. Reserve ahead for busy summer weeks, ask for climbing-friendly gearing when you book, and bring your own pedals, shoes and helmet so the fit feels familiar.
