(2) Continue and pass a cemetery on your left for a good hundred metres.
(3) Leave the tarmac road and take the path on the right. Cross a wood and continue in the same direction until you reach the hamlet of Villelonge. Cross the D7 with caution and continue straight ahead for about 60 metres.

(5) Take the path opposite, which descends towards the Lioussel stream. This path turns right and then descends along the edge of the stream. Take the path that runs along the stream to the left until you reach the chasm. The path takes you down to the chasm opposite the waterfall.
(6) After enjoying this little corner of paradise, climb back up to the crossroads.
(5) Take the path on the left that crosses the fields with a view of the Mézenc. Come out onto a wider path and follow it, turning right.
