Start from the large car park on the edge of the Route du Leat de la Chaille, near no. 2400 and the Leat de la Chaille.
(S/E) From the car park, take the Route du Bief de la Chaille downhill. Walk past No. 2400 and you’ll soon come to a path on the left.
(1) Follow this path down to the next fork.
(2) Turn left and you’ll soon reach the Cascade du Bief de la Chaille.
(3) After taking in the view, head down the narrow path that runs alongside the stream on the right bank until you reach the fork with a footbridge on the left.
(4) Carry on to the right and you’ll soon reach a fork. Keep to the right and return to a junction you’ve already passed.
(2) Turn left and head back up the path you came down, following the route in reverse, until you reach the car park (S/E).
