Start from the first car park at Parc de Saint-Pons, i.e. the one furthest to the west.
(S/E) Head towards the village and, after 200 m, take a path up to the right which joins a small track. Continue for about 40 metres. Please note that the GPS track does not correspond exactly to the route, but this does not hinder progress in any way as the paths and junctions are clearly visible throughout the route.
(1) Head up a path on the right. After 250 m, turn left and continue for about 500 m.
(2) Ignore the path that continues straight on at the bottom of the valley and head down to the left to resume the route; the path then climbs quite steeply.
(3) After 1 km, join a track and head straight up. Note that at each bend you can either cut across the bend via an easily identifiable path (which is what is shown here), or continue along the track for a gentler climb. Walk for about 1 km.
(4) Follow the track branching off to the left for 2 km.
(5) At a left-hand bend, look for the start of a small path that branches off to the right, heading west. About forty metres further on, turn left. This is the start of the climb up to the Col de Brest.
(6) 250 m further on, follow a path leading off to the right uphill to reach the Col de Brest.
(7) Continue straight on along the path heading south, ignoring a path branching off to the left. You’ll come to a track.
(8) Cross it and, opposite, you’ll find a path that descends around the bend towards the Vallon du Gour de Brest. This marks the start of a very stony descent. Watch your step. Keep going straight on, ignoring any turn-offs to the right and left, for about 1,500 metres.
(9) At the bottom, head left for a few metres and cross a small bridge, then turn right onto the path leading to the Parc de Saint-Pons. Head west to return to the car park (S/E).
