From Agay, take the D100 towards Fréjus for 2 km, then turn right towards the Estérel mountains and finally Col de Belle Barbe 3 km further on. Park in the car park at the pass.
(S/E) The trail starts on the right, descending to join theGR®51(white and red markings). Follow the valley on a wide track until you reach a fork just before a ford on the Infernet.
(1) Turn left, cross the ford and continue to Lac de l'Écureuil (dry at the end of summer).
(2) Go around it on the left for 500 m, then descend to the right onto the banks of the ravine.
(3) Leave the path that branches off to the left (GR®51) and take the very steep, shaded path of the Ravin de la Dent de l'Ours, which climbs towards the Pic de l'Ours (be careful, the start of this path is not very obvious as there are no markings and very few cairns until the summit of the Dent de l'Ours). At the end of the ravine, the trail winds through a few wide switchbacks and arrives at a fork.
(4) Turn left and continue to the summit of the Dent de l'Ours (sign).
(5) Continue to the right, following the blue and yellow markings towards Pic de l'Ours for 500 m, then take the blue markings on the left to reach the summit.
(6) From Pic de l'Ours, follow the paved road for a few metres and take the path on the right (not easy to find, a GPS or IGN map is essential) which leads to Col des Lentisques, crossing the road twice.
(7) At the pass, turn right onto the road for 50 metres, then take a wide track on the right which descends to the ford you passed at the start.
(1) Once in the Vallon de l'Écureuil, return to the car park by following the route in reverse (S/E).
