The Port of Lers is a crossing point which offers a beautiful panorama where you may be lucky enough to see Mertens black horses. It is also a place which has seen the Tour de France pass many times.

The Soulcem pond is a reservoir designed in the 1980s on a former plateau dedicated to pastoralism. Today it is the meeting point of many hiking trails that connect France and Spain. The place is worth a short break to enjoy the view of the Vicdessos valley.
