Not to be attempted after a period of rain, as the route becomes like an ice rink, making every descent dangerous (three falls in one hour).

A pleasant walk without any major points of interest. However, it is enjoyable in the forest, and at times for its views of the Pyrenees...

Few points of interest and a forest that is far from pretty.
Don't go there to see the pond, you can't see anything...
Disappointing hike.

The first part is very pleasant in the woods, especially in sunny weather. The last part is a little less so, as it takes place partly on tarmac and without shade.

We enjoyed a pleasant circular walk, going "the other way" and parking at the picnic area (point 4).

The start of the path (point 1) is not very visible.

There are few (if any) markings between point 1 and the arrival/departure point. This section can be very muddy in wet weather.

A very pleasant walk. Best done in dry weather as there is a lot of mud in places when it has rained.
The signposting has been redone recently, so it's impossible to get lost.

A beautiful hike through forest and unspoilt countryside. No difficulty. Varied vegetation to explore accompanied by the sounds of numerous birds.
At point 5, you can turn right to reach the observatory on the alluvial plain, which is just a few metres off the hiking trail.
