Depart from the roundabout at the exit of Vernet-les-Bains towards Casteil (roundabout of 18 June 1940), at the thermal spa.
(S/E) Take the paved path that climbs northwards, following the sign for Pic de l'Alzine and the yellow and white markings for Jardin d'Hiver.
Shortly afterwards, you will reach some steps; take them on the right. Continue along a path that climbs steadily in a zigzag pattern. At an altitude of 750m, you will reach a crossroads.
(1) Turn right, heading south towards Plateforme de Burnet. The path continues to climb steadily. Enjoy the view before turning left and climbing a long slope to reach Pic de l'Alzine (altitude 1,017 metres). After the peak, descend to Col de Llavent (altitude 958 metres).
(2) From the pass, take a 30-minute round trip (+80m elevation gain) to see the Dietrich Waterfall.
(3) Return to the pass junction.
(2) Continue straight ahead towards Vernet, northeast. Begin a short descent, pass by a beautiful orry, cross the Rabent canal and arrive at another crossroads.
(4) Leave the route marked on the map, which continues downhill towards Vernet-les-Bains, and turn right (east). The path climbs again and is marked with red dots.
Please note: if the weather is bad, continue on the marked trail and join the trail at elevation 800 (see Practical Information).
Continue climbing steadily and follow the red markings to an altitude of 1,220 metres. After Coll de Lloseta, you will reach another fork, which is the highest point of the hike (1,225 metres).
(5) Turn left, north-east then east. The path descends slightly then climbs again and at around 1230m it heads north-west, ending with a descent that is gentle at first but then becomes steeper and very steep in places.
There is no particular danger in dry weather, but this section is still reserved for experienced hikers.
At an altitude of 980m, join the marked route to the Cascade des Anglais waterfall.
(6) Turn right to reach it 100 metres further on.
(7) Retrace your steps to return to the previous crossroads.
(6) Continue straight ahead on the marked trail, cross several bridges and pass in front of the Cascade de Saint-Vincent waterfall. The descent is easy, just follow the markings. You will return to the crossroads at an altitude of 800 metres.
(8) Continue downhill and reach the path at the information point.
(9) Leave the road and turn left towards Vernet-les-Bains, Jardin d'Hiver, following the white and yellow markings. After 200 metres, turn left and climb up to join the uphill route at the first crossroads from the start.
(1) Follow the outward route to return to the car park (S/E) (yellow and white markings).
