From Aurillac, take the N122 towards Le Lioran. After passing through the tunnel, turn right at the second junction at the roundabout. Follow this road for 480 metres, then turn right near the ski lift and park immediately to the left of the road in the car park near the shops.
(S/E) Follow the road up to the first signposted junction just before the current sports shop. At the sign, turn right, then immediately left towards the north-west onto the small tarmac road. This quickly turns into a track and leads to a junction.
(1) Ignore the track branching off to the left (which you’ll use on the return journey) and take a sharp right-hand bend towards the Téton de Vénus. The track, which is signposted at every junction, climbs steeply through the forest before emerging from it and becoming a footpath beneath the Rocher du Bec de l’Aigle at an altitude of around 1,500 metres. Follow this path round the rock on the left and, after a steep climb over scree, join the GR®400 and the summit cairn of the Rocher du Bec de l’Aigle.
(2) Continue westwards along this ridge dotted with gentians until you reach the next junction at the foot of the Téton de Vénus.
(3) After passing through the metal gate, leave the GR®400 and turn right onto the summit path. Follow this ridge path, which climbs through the grassy slopes, to reach the Téton de Vénus.
(5) Descend the opposite western slope towards the Puy Bataillouse. Via a climb that is not much more difficult but slightly longer, reach the summit area of the Puy, marked by its cairn.
(4) Return to the Téton de Vénus via the same route you took on the way up.
(5) Turn sharply right and head down the path to the south until you reach the GR®400.
(6) Turn right onto the GR®400 and continue until you reach a signposted junction.
(7) Take a hairpin bend to the left, then head down to the Buron de Meige Costes.
(8) Head down the GR® until you reach a road.
(9) Turn left and head up this road, which will quickly turn into a lane. Continue along this lane until the next junction, where you should turn left and then head back to the crossroads from the outward journey.
(1) Follow the same route back as on the way there until you reach the car park (S/E).
