From Castillon-village to Monti via Mont Mulacié

The walk starts from the Castillon-village bus stop or from the lowest car park in the village.

(S) From the bus stop, follow the road up towards the village, then head towards the first car park and walk past marker 130 (located opposite the restaurant ‘La Bergerie’). From the marker, follow the signs for the Col de Castillon. The route follows a road.

(1) At marker 131, the road turns into a footpath. Take the path which leads up through the woodland, still heading towards the Col de Castillon. Ignore the sign stating that the path is impassable; it is perfectly passable and well-maintained.

(2) Join the road that runs through the Remégon neighbourhood and follow it. It is marked by a few yellow signposts. Continue until you reach signpost 133.

(3) At marker 133, you’ll reach the road leading up to the Col de Castillon; cross it to join a path on the opposite side that descends slightly through the woodland. Follow it, keeping an eye out for the yellow markings, until you rejoin the pass road a little further up.

(4) When the path rejoins the road, cross it and then head slightly uphill along the concrete track. Head straight ahead towards house number 5824 and, just before the property gate, turn left at marker 134. Then follow the path and the yellow markers to the Col de Castillon, which you’ll reach quickly and without difficulty.

(5) At the Col de Castillon, follow the signs for the Baisse de Scuvion, indicated by marker 135. You will then walk along a road and then, shortly afterwards, along a well-marked path (from marker 136); follow the yellow markings.

(6) At marker 137, continue towards the Baisse de Scuvion. The slope becomes steeper but the going is easy right up to the pass.

(7) Reach marker 92, situated just below the Baisse de Scuvion, which you’ll reach very quickly; from there, follow the signs for the Col de Roulabre along a gently descending path through the forest.

(8) At the Col de Roulabre, continue downwards, heading towards the Col du Razet.

(9) At the Col du Razet, carry on straight ahead towards the east, heading for the summit of Mont Mulacié. An unofficial signpost indicates the direction to follow. The route is easy at first, following a relatively well-marked track, but becomes more challenging once you leave the forest. As for finding your way, simply follow the numerous red and blue markings, which indicate the path to take.

(10) At this point, the blue and red markings split; you must now follow the red ones to reach the summit. This is the most technical part of the climb; you need sure-footedness, as there is no longer really a defined path.

(11) Summit of Mont Mulacié. Retrace your steps back to the Col du Razet.

(9) Once back at the pass, take the path leading down towards the Col Saint-Bernard. Follow the yellow markers.

(12) At this point, near Villaron, take a small path on the left, the start of which is marked by a cairn on a rock. This path cuts across the hairpin bends of the track, which you’ll rejoin a little further up.

(13) Col Saint-Bernard. Head towards Monti and follow a very steep path marked with yellow markers. At the start of the descent, watch out for the numerous goat tracks which can be misleading; therefore, make sure you spot the yellow markers clearly, as they are sometimes hard to see because they have been worn away over time.

(14) At marker 418, cross the road and take the track opposite. Turn right; as you come out of the bend, turn onto a path marked at the start by a yellow marker on a post. The path joins a track at marker 417.

(15) Marker 417: ignore the path opposite which leads up towards Castellar. Head down along the concrete track; a sign reading ‘Itinéraire pédestre’ (Walking route) points in this direction. Follow the red and white markers of^{the GR®} 51.

(16) At marker 434, head towards Monti and continue to follow the red and white markings until you reach the car park in front of the church (E).

The walk requires two cars: one to be left at Monti, and the other to take you to the start point at Castillon.
You can also complete the route with just one car, which you leave in Monti; in this case, you’ll need to take the bus to the start point in Castillon (check the timetables for the Menton–Sospel route).

If you choose the two-car option, the walk starts from the lower car park in the village of Castillon; if you choose to take the bus up to Castillon, the walk begins at the bus stop, situated slightly below the village (this is the option described here).

Please take care on the round trip to the summit of Mont Mulacié: the second part of the ascent is very steep, following a barely marked path over terrain that can become very slippery after a day’s rain or when there are fallen leaves on the ground . Be particularly careful on the descent.
