Park at the car park at the start of the Lac de Creno walk: please note that you’ll need to get there very early in July and August.
(S/E) Take the access path to Lac de Creno for about a hundred metres until you reach the donkey and horse hire place. 50 metres further on, leave the Lac de Creno access path, turn left uphill and take the track that runs on level ground for 15 to 20 minutes.
(1) Beneath the huge chestnut trees, look for a path below the track that winds more or less in zigzags down through the bramble thickets to the stream. Turn right and follow it upstream for a few minutes, then rejoin the track, which you follow to the footbridge where canyoning enthusiasts set off.
(2) Cross the footbridge and walk upstream along the right bank of the stream, then move closer to it.
(3) A sloping rock slab with a waterfall, pools and hanging gardens: you’re in paradise.
You can follow the stream upstream as far as the bend and probably beyond.
(4) The return journey follows the same route back to the car park (S/E).
