Turn left, heading east on theGR®10and GRP®. The path climbs through the pasture towards Portella de la Grava.

Descend via theGR®10towards Estanoll (altitude 2297). Natural lagoon, streams, animals.
(9) TheGR®10turns south-east in Coume de la Grava, following the Rec (torrent) de la Grava, then the Têt to arrive at a large natural lagoon area. Reach a fork in the road.
(10) Stay on theGR®10. Do not turn right towards Estany del Reco (unless you are doing a return trip).
(11) At this point, the Rec de la Llosa (torrent de la lause) joins the Grava to form the Têt. Continue along the right bank. You will arrive at a beautiful lagoon area and reach a fork.
(12) Directional signs. Turn right heading south along Lac des Bouillouses on your left. This long, complicated and damaged path allows you to discover superb spots with small beaches. Gaps in the vegetation allow you to discover this beautiful artificial lake. Reach the restricted access road to Bones Hores.
