Crossing of Mont Jalla

From the entrance to the Jardin des Dauphins (note garden opening hours: 9 am - 8 pm in summer and 9 am - 6 pm in winter), climb up to the Bastille [sentier de la Mémoire et de la Paix] via the garden's paths. Starting from the Guy-Pape garden, the itinerary is a succession of paths, staircases and passages through the fortifications. From the dungeon courtyard (below the cable car entrance), exit through the postern and turn right onto the track leading to Mont Jalla (junction with GR ® 9) [caves known as the Mandrin caves]. Before the Père Gras inn, turn left onto the fire-fighting track that climbs to the summit of Mont Jalla (630 m). Reach the crest (post "La Chenaie"). Leave the GR® 9 and turn left towards the memorial. At the memorial, turn right towards Mas Caché. Turn left onto a steep path, descending rapidly to Mas Caché. Descend by the road for about 150 m [view of the Aiguille de Quaix]. Turn left along a housing estate. At Gomma, cross the D57 to go straight ahead on a wide, undulating path through undergrowth. Cross two small bridges and climb up to Gatinet. Take the small road to the left, round the Château de Narbonne and continue downhill for around 150 m. Along a hedge, take a path on the left (sunken road, steep descent) to Le Canet. Cross the road and descend to Pique Pierre via Place des Compagnons Charpentiers, Chemin de la Cheminée and Route de Narbonne. Return by streetcar E to the "Saint-Martin-Le-Vinoux - Hôtel de Ville" stop. You can walk back to the Esplanade along the cycle path that runs alongside the Isère river.
