GRPdesBF 418-420

The bordermarkers of the Pyrenees : the GRPdesBF

- stage 32-
Arriu des Grauèrs - Port d'Orle (bm418-420)

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
We enter the high mountains. The main route climbs on a waymarked trail to the derelict mining buildings of Liat (including a cabin) and climbs then more gradual towards Port d'Urets. Then - after climbing a 27oom pass - it descends and continues to Port d'Orle (bm420).
The variant starts immediately with a steep climb up a gully and then traverses above the lake of Estanh Long de Liat towards Port de la Hourquette (bm418 and 419) and then descends to join the main route.

Considerations
The main route passes the well equipped cabin of Mines de Liat, though quite early. Along the main route, there are enough bivouac spots but watersources are scarce. At the end of the stage - Port d'Orle - a bivouac will be difficult in the rocky terrain and by lack of fresh water. You might consider to stop earlier somewhere along the stream of Ribèra d'Òrla.
On the French side however of Port d'Orle (when descending to ± 2100m) there's a small metal cabin with a source nearby. Alternatively you could already descend into Spain to find a place to bivouack

- 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 from corrected NASA SRTM3 data with GPS-Track-Analyse.NET - 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) * = including overlap of 2 bm's with previous stage								Bm's covered cumulative:
