This long bar alternates between multi-pitch routes, shorter sport routes and children's sections. On the whole, the routes are fairly steep slabs and walls with straightforward holds. Appropriate skills and equipment (helmets recommended, as rock falls are common).
A detailed document on the sites is available for consultation at Alpe d'Huez Tourisme.

Take the footpath signposted ‘site d’escalade’ which will take you to the central ‘secteur’, called ‘Ice Bill’ (15 minutes). A sign shows you where the other climbs are, but they are all easily accessible within a 5 - 10 min walk. During the tourist season, the site can also be accessed from Oz-en-Oisans using the Poutran cable car, followed by 15 minutes on foot.
