The trouble of this difficult bit is the great height of the lateral ridges. At the end of this fine valley of Arazas, which curves slowly up northward as you go, is the huge mass of the Mont Perdu, and you cannot get out of the valley without going over the shoulder of it. In order to do this proceed as follows, and go along the stream until the path crosses over from the northern to the southern bank, at a place where the cliffs on either side come very close to the water. The path goes along under and partially upon the face of these cliffs in a perilous sort of way, until it comes to a lateral streamlet pouring right down the side of the terminal mountain. This lateral streamlet you must be sure to recognize, for upon your recognizing it depends the success of your adventure; and you may know it thus: The place where your path strikes it, is exactly 1000 yards from the place where you crossed the main stream. When you come to this lateral streamlet you will see, or should see, a transverse path running very nearly due east and west; and up that in an eastward direction, immediately above you, a distance of 800 yards, upon the shoulder of the great mountain is the depression for which the path makes. It is called the Col de Gaulis.

For all of this by the way you will do well to consult Schrader the whole time. What the going is like on the further side of this col I cannot tell for I have never come down it, but I know that your way descends right by a very short and steep gully in which a torrent makes straight for the valley beneath, and I know that when you have made that valley your troubles are over.

You fall through a descent of just under 2000 feet in a distance of less than a mile as the crow flies. You must therefore be prepared for a very steep bit of work. Once in the valley, however, everything is straightforward. On reaching the main stream of this new valley (which runs north and south) you turn to the right, southward, and follow its right bank between it and the cliff; you cross a rivulet flowing from a deep lateral ravine about a mile further on, and less than half a mile further again see a new path leaving your path and going to your left, crossing over the valley and its stream, and making up a gulley which comes down facing you from the opposing heights. Take this new path up this gulley (the path runs everywhere to the south of the water), and you will find yourself after a climb of somewhat over a 1000 feet on the Col d’Escuain. Thence the way is perfectly clear, running due south-east for 5 miles, just above the edge of the cliffs of the gorge of Escuain, until you reach the village of Escuain perched above that ravine.

Whatever efforts you may have made, and however early you may have started, you will hardly have reached human beings again at this place until, as at Bujaruelo the day before, the back of the day is broken. Nevertheless, unless you are to camp out again upon the mountain, you must try and push on to Bielsa. It is more than 10 miles, however much you cut off the windings of the path, which takes you past the chapel of San Pablo, leaving the village of Rivella on the left up the mountain side, then across a steep cliff down to the profound gorge of the Cinca; from there an unmistakable road goes through Salinas de Sin and follows straight on up the valley to Bielsa just 4 miles further on.

If you can do that in one day you will have done well.

There is another and shorter crossing, which, though it is invariably used by the mountaineers, I have not described because most people unused to the Pyrenees would shirk it. When you have come down from the Col de Gaulis into the valley below, if instead of going southward to the right you go northward to the left, crossing the stream, and climbing up on the further side of it, the path takes you at last to a very high col, called in Spanish the Col of Anisclo, but in French, the Col of Anicle. This col is not far short of 9000 feet high, and it is particularly painful to have to attempt it just after the difficult business of the Col de Gaulis. It means two ports within a few hours of each other, the second one 3000 feet above the valley, and what that is in the way of fatigue, a man must go through in order to know. Moreover, the descent on the far side from the Col of Anisclo is exceedingly steep.

However, if you do this short cut you have the advantage of finding yourself at once in the main valley of the Cinca and, when once you are on the banks of that river, you are not more than 8 miles or so from Bielsa by a good path leading all the way down the stream on the left bank. You save in this way quite 6 miles, and reduce your whole journey from the mouth of the valley of Arazas to Bielsa to a little less than 20 miles.

The distance you have to go before you come to human beings is much the same by either track. Escuain is just about as far from the Col de Gaulis, as is Las Cortez, the first hamlet in the Cinca valley. Again, by this shorter way you miss the gorge of the Escuain, but you see the huge cliffs of Pinède, which are perhaps the finest wall in the Pyrenees with their summits along the crest of 9000 feet, 5000 feet or more above the stream at their feet: it is the edge of this ridge of cliff which must be crossed at the Col of Anisclo. Either way therefore is as fine and either as deserted as the other. But the second much shorter and far more painful.

Before I leave this passage between the first and second of the Sobrarbe valleys—between the valley of Broto, that is (as they call the valley of the river Ara) and the valley of the Cinca—a few notes on the road should be added.

First, I have said that Torla, Bujaruelo (Boucharo) may be made from Gavarnie as well as from Panticosa. This is so; and if you undertake the exploration of Sobrarbe from Gavarnie, it is a much easier business to get to Bujaruelo from the French hamlet, than it is to get to it from Panticosa.
