Step-by-step guide : Special recommendation: be careful, patous on the area Itinerary: The start is located near the Col de la Colombière chalet-restaurant. Follow the marked path "Grotte de Montarquis (2h20)" and quickly leave the other path to the left which leads to the Jalouvre. After a 30-minute walk, you arrive at the Chalets de la Colombière. Then turn right towards the cave. Follow the hilly path and cross a park where there is a flock of sheep. Continue like this for 25 minutes, until you reach the sign "Montarquis (Ruines)". The path then becomes steeper, leave the park and turn left at the small sign “Grotte de Montarquis”. Continue for 35 minutes before reaching the final climb (about 45 minutes) in a scree. At the top, enjoy the life on the Aravis massif and the fresh air that emanates from the cave. The descent is made by the same path as on the way out.
