Car park at Place Gilles Léontin in Boulbon.
(S/E) From the car park, turn left onto Rue de l’Église, then take Rue de l’Hôtel de Ville, which veers off to the left. When it joins Rue de l’Enclos, turn right and then immediately left onto Rue de la Clastre.
(1) Turn right onto Chemin de la Montagne, then very soon after turn right onto Chemin du Prieuré, which climbs to the right towards the church and the cemetery.
Go round the cemetery on the right, pass through a gate and follow a path that climbs to the right towards Moulin Bonnet.
This path was no doubt marked in yellow at one time, but there are now hardly any trees or markings left. Continue along this path; at a sharp right-hand bend, ignore the path branching off to the left and carry on climbing the track for about 200 metres.
(2) At the junction, turn right to pay a quick visit to Moulin Bonnet, which offers a lovely view of the village of Boulbon.
(3) Walk round the mill and retrace your steps to return to the junction you left earlier.
(2) Then head straight on along this main track to continue the climb along the Montagnette ridge. Ignore all the paths branching off to the right or left and stay on the main track. At one point, you’ll see more yellow markings. Carry on until you reach a crossroads with several tracks. Look out for a small artificial reservoir on the left as a landmark.
(4) Do not take the path on the left leading towards Saint-Michel-de-Frigolet Abbey (it is possible to make a round trip to see it, but the signposting is poor and there are many paths).
Do not take the path straight ahead either, nor the one veering slightly to the right, but take the one veering sharply to the right, marked by a cairn. It descends into the valley and will be clearly marked in yellow all the way to the village. Walk down this valley without worrying about the other paths.
(5) When you reach a bridge, take the path on the left which goes round the castle. Then take Rue Gaston Raousset straight ahead, followed by Rue du Barri, which bends to the right to take you back to the car park where you started (S/E).
