The start is from the Hauts Gicons car park near the pylon (this is the only place where you won’t be in anyone’s way).
(S/E) Retrace your steps for about a kilometre, passing through the hamlet of Les Hauts Gicons, and return to the crossroads of the paths at Les Bas Gicons.
(1) Take the path leading off to your right. Keep right at the next fork, then do the same when you reach a wide track. Pass the 1351m mark and reach a crossroads 100 metres further on.
(2) Take the middle path heading due north and follow it for about 700m. As you emerge from the forest, it branches off to the west and follows the contour line roughly to the edge of the cliff.
(3) Take the well-marked path that climbs to the right, ignoring the cross on a tree, and walk along the cliff. Pass a small promontory.
(4) Continue along the cliff until you reach the summit of Petit Brechon (1,618m).
(5) Move away from the cliff slightly, descend to cross the gap separating the two Brechons and climb off-trail to the summit of Grand Brechon (1753m).
Look out for the shepherd’s hut and his caravan below at elevation 1607m, with the Combe des Chèvres ridge and the Gicon directly opposite you. Descend on sight to reach it and cross the small rocky outcrop protecting the hut; the passage is on the right.
(6) Take the forest track that starts below the hut and follow it to a crossroads.
(7) Continue straight ahead, slightly to the right, keeping a southerly bearing to reach a fork.
(8) Continue straight on to reach Les Hauts Gicons. Once you reach the tarmac road, continue to the left to return to the cars (S/E).
