|A Walking Guide to the Massif de la Chartreuse|
Walks on Dent de Crolles (2062 m)
For the purpose of this guide, the Dent de Crolles area is deemed to include the long, narrow, upland area stretching from the col du Coq, at the southern end, to the col de Bellefond (also known as col de Bellefont) in the north - a distance of some five or six kilometres (map). A line of cliffs divide it into two discrete sections, with the plateau of the Dent de Crolles in the south, and the Chaos de Bellefond in the north. The only practical ways through these cliffs is by means of the Cheminée du Paradis, a chimney situated at the eastern end, close to the steep escarpment overlooking the Isère valley, and a rake which rises through them at the western end.
The Dent de Crolles has more routes on it than any other part of the Chartreuse. This, no doubt, is partly due to its ease of access, and partly due to the fact that its summit totally dominates the Isère valley below. However, the main reason must simply be that it offers magnificent walking.
The easiest approach is from the col du Coq, one of the high road passes between Chartreuse and the Isère valley. This climbs to within 600 metres of height, and 1,500 metres in distance of the summit, and has convenient parking at the top.
To the west, Perquelin offers a variety of routes to the plateau, allowing a number of circuits to be constructed. All routes from here involve over a 1,000 metres of ascent.
To the east, a route ascends from the Commune de St. Hilaire, which is perched on a narrow plateau perched half way up between the escarpment above, and the Isère below.
The Dent de Crolles is not only a magnet for walkers, it is also a place of pilgrimage for cavers. The area under the summit contains well over 60 kilometres of mapped caves, with many more yet to be discovered. It is possible to descend almost from the top of the mountain, all the way to the source of the Guiers Mort some 650 metres below, and it is possible to traverse right through the mountain, from one side to the other. Whilst such expeditions are for experienced cavers only, you should take the opportunity to take a look at some of the more accessible caves. It's always worth carrying a couple of light-weight headlamps.
