GRPdesBF 410-417

The bordermarkers of the Pyrenees : the GRPdesBF

- stage 31 -
Pont du Roi - Arriu des Grauèrs (bm410-417)

Only the bordermarkers on this stage are shown (and some adjoining ones). The main route is red, the variants are blue. Click here for a fullscreen interactive map.

In short
The main route is a nice walk climbing to the pictoresque hillside-village of Canejan and continuing along old trails on the mountainside and through the forest. However: passing no bordermarkers, apart from bm410 at the beginning. The long variant takes care of the bordermarkers but involves heavy climbing, tough terrain and requires wayfinding (and bm-finding) capabilities. Both (main route and variant) end at the upper end of the valley where a footbridge passes the stream.

Considerations
The main route provides enough water refuelling options. It passes the Refugio dera Honeria after 10km. At the end of this stage (at the footbridge) a bivouac should be possible (I did that on 27 august 2006).
When taking the alternative route along all the bordermarkers, you need to take enough water. There are some watersources but they might be dried up in (late) summer. The variant passes two cabins (la Trauès after 10km and le Plan 2km further) but I'm not sure how public or private they are.

- 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 according to the NASA SRTM3 database, derived through Gpsvisualizer: - km & elevations according to 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) * = including overlap of 1 bm with previous stage								Bm's covered cumulative:
								455
								Bm's cum. on main route:
								301
