There are a few parking spaces along the road in Lindarets.
(S/E) From the village of Lindarets, follow the paved road towards the ski resort. When you reach a fork, turn left onto Route des Lindarets.
(1) Turn left to follow the Lindarets road. Pass the upper station of the Ardent cable car and follow the sign for "Les Barnettes" in front of the restaurant "Les Alpages".
(2) At Les Barnettes, take the path on the right above the restaurant "Les Alpages", following the direction indicated by the signpost "Les Brochaux". Follow the path below the Léchère chairlift, along the river. The path climbs gently but steadily, sometimes through the forest, sometimes through clearings.
(3) Stay on the right side of the river until you reach the entrance to the forest to reach the village of Les Brochaux, then the waterfall.
(4) At Les Brochaux, cross the bridge and continue straight ahead to reach the Cascade des Brochaux, which is already in sight.
(5) Return by the same route to the car park (S/E).
