Porteille de Mantet - Col d'Ares (bm511-519)

previous stage       next stage

Only the bordermarkers along this stage are shown (and some adjoining ones). The main route is red, the variants have other colors. The main route provides a smooth on-going route along most bordermarkers, the variants give access to the remaining bordermarkers. See the GRPdesBF-principles.

In short

A gradually descending stage, leading you from a rocky and exposed ridge to a lower and greener hillridge. We are leaving the hight mountains behind us and until the Mediterranean we won't exceed the 1600m again.
From bm511 we can follow a trail N of the borderridge until Portella de Callau. Then directly climbing to Roc Colom (bm512) and along the borderridge to Coll del Pal (bm513). On the S-side of Pic de Costabonne we can now traverse to the borderridge 1,5km to the SE without having to climb the Pic. And then it's essentially following the grassy hillridge on trails and sometimes dirtroads until Col d'Ares with bm519.

Considerations
There are in generail no wayfinding-issues.
Water is scarce: there is only one source on the trail:  at the S-side of Pic de Costabonne. When studying the maps, I spotted however a source 250m N of the col just W of Puig del Rey ("Font de l'Artique d'En France"). That's 1,2km W of bm515. The next stage is also scarce in water sources so you have to collect enough to get through the next day as well.

incl. all variants
No variants in this stage
- the main route is a smooth trail along the border and most of the bordermarkers (within 100m reach of the main route)
- the variants allow you to visit the remaining bordermarkers
- altitudes are derived with Gpsvisualisizer using NASA SRTM1-data
- km & elevations statistics computed in Basecamp
- time according to
Naismith's rule with average speed 4km/h; 10 min. extra for every 100m ascent and 5 min. extra for every 100m descent. Don't forget: this is a rough estimation.
- (+ or -) = extra km & elevation & time compared to continuing on the main route)
