## Departure Departure 1.5 km under the pond of Lers at the Lamarda bridge (1200 m). ## Go Follow the long track that leads up to Rose's cabin (some shoelaces can be cut).
From the Col de Rose (1615 m), climb up the W ridge of Pic de Barrès where you reach the SW ridge of Pic des Trois Seigneurs.
Follow the ridge avoiding the deep breach by the E. ## Return The choice is yours: - by the same route - through the Arbu pond: follow in the opposite direction [[roads/195557|the route of the Arbu pond]] (yellow markings).
Once you reach the road, go up a hundred metres to cross the port of Lers.
Follow for a few moments the road towards Massat and then go down off-trail the slightly sloping valley.
Pass left bank and move away from the creek a little when the bushes appear to reach the starting point.<br/><br/>_This Adventure has been shared under the [Creative Commons Share Alike](https://creativecommons.org/licenses/by-sa/2.5/) licence._
