From Nice, drive up the Var plain, heading towards Carros then Le Broc before arriving at Bouyon and finally Bézaudun-les-Alpes (road leading to Gréolières). Park in the small car park opposite the fountain.
(S/E) Cross the village heading north to reach marker 7 and the start of the hike. Leave the paved road and go down the small staircase.
(1) At marker 8, continue west towards L'Estelier. The path descends gently towards Le Bouyon below.
(2) The IGN map shows what appears to be a bridge here, but there is nothing on site. Continue up the track and then cross (roughly where I have indicated on the map) the stream that runs underground here; you can cross and rejoin the path opposite. Follow it to the left and then climb gently until you reach the track.
(3) At marker 112, head west towards L'Estelier and stay on the track until you reach marker 113.
(4) Leave the track here and head north into the forest.
(5) Here you will come across a marker that is not shown on the IGN map, No. 114a. Turn right, heading east towards L'Estelier, which you will reach by following the ridge (magnificent 360° view).
(6) Continue along the ridge. The path will quickly begin to descend to follow the Moul stream.
(7) When you reach marker 100, turn right towards the village of Bouyon.
(8) Continue south-east along the path which winds down towards the village.
(9) At marker 6, head towards L'Aiguillette and Bézaudun. The track will turn into a path before becoming a track again, following the D8 just below. The path is well marked. Continue along the track until you reach the road and the bridge over the Bouyon. Bézaudun should soon appear in front of you.
(10) Cross the bridge to find marker 111, then follow the path up to marker 8.
(1) Return to the village on the left and cross the village again via the small street in front of you to return to the car park (S/E).
