Park at the power station car park at the very end of the D66.
Take the path to the west. At the fork (1), ignore the path on the right to Orris de Mespelat and continue straight on, following the Artigue river for about fifteen minutes. At 1203m, a footbridge takes you across the river onto the right bank. (2). After ten minutes you will reach a fork on the right leading to the Artigue waterfalls. (3). Walk through the undergrowth, with blueberry bushes on either side of the path, until you reach the steep banks of the Artigue. The most dramatic spot is where the Estats and Artigue rivers meet.
Return to the car park along the same route.
