The hike (or walk) takes place on the south-eastern side of the Mont Coronat limestone massif. Park in the small car park opposite the start.
(S/E) Start the hike at the oratory (Montjoie) on your left. Take a small path on the left through the copse.
Then just follow the path marked with thick white paint, which is very well maintained and winds along the mountainside. It's impossible to go wrong as there is only one path. The few false trails that deviate from the main trail are clearly marked by piles of stones, indicating that they are not the right way. After 15 minutes of climbing (approximately 800 m horizontally), with the mountainside on your right, you will reach a hairpin bend.
(1) Turn sharply right to continue climbing with the mountain on your left for about 10 minutes (400 m horizontally). You will reach the chapel esplanade.
(2) You can access the large cave above the chapel by taking the path that passes to the left of the chapel. You will first arrive at a beautiful viewpoint. Continue for a few minutes along a moderately difficult path to reach the entrance to this majestic cave.
(3) Begin the return journey by following the same path you took on the way there to return to the car park (S/E).
