How to find it

Puits des Cartusiens is not that easy to find. Follow the GR9 from Col du Coq on the plateau, and continue past the junction with the summit path for about 700 metres. Look for an old pine by the path which has a 90° bend just above head height and 20 metres past this, go up the slope for about 150 metres. The cave is obscurely tucked under a small cliff with a pavement in front, and may have a belay cord hanging from a tree. A GPS is strongly recommended! One can also find it from the path that traverses under the eastern flank towards the Cheminée du Paradis. The path drops down sharply when it crosses a small cliff - follow the shallow valley below the cliff down for about 130 metres to reach the same area of pavement.

Further information

First explored in 1959, the Puits des Cartusiens was finally linked to the Grotte du Guiers Mort in 2007 and enters at the Galerie du Solitaire. An account of the original exploration by members of the Spéléo Groupe La Tronche may be found here. A good description and cross-section by Jean Philippe Grandcolas and others is also available. Accounts indicate that the pitches become damp in wet weather.
