This pass is the highest and steepest on the secondary or lateral passes, over which the new roads have recently been driven. It is just under 7000 feet in height, is everywhere practicable, and once it is surmounted there is a clear run down of some 10 miles and more (following the valley called locally that of the Bastan) to Vielle and to Luz in the main valley.
Of all the crossings between the high valleys of the Pyrenees this is the one best worth taking. The height of the pass, the great mass of the Port Bieil dominating one side of the road, and of the Pic-du-Midi dominating the other, give it an aspect different from any other of the secondary roads, and comparable only to the two main passes of the Somport and the Val d’Ossau.
From Luz a great national road takes one down the valley to Argelès and the railway, a distance of about 18 miles, and the end of about as fine a piece of engineering as there is in Europe. From Argelès, which is just above Lourdes and whence Lourdes can be reached at once by road or by rail, the cross road which I am describing goes on over another high pass into the Val d’Ossau.
The motorist must decide whether to make Argelès his stopping-place or not. In distance from Bagnères he will have gone no more than somewhat over 70 miles, and that is a short day; but it is a day that will have included a great deal of climbing and of sharp descents, and that will have had at the end of it one of the highest passes in the Pyrenees. If he does not choose to stop at Argelès, he will find in Eaux Bonnes above the Val d’Ossau, rather more than 20 miles on (but over a high pass), a very wealthy little modern town, like Bagnères on a lesser scale, with everything that he or his machine can want; and only an hour or an hour and a half beyond Eaux Bonnes, by one of the great national roads and along the lowlands, is Pau.
This cross road from Argelès and the valley of Lourdes, into the Val d’Ossau runs as follows. You take at Argelès the road for Aucun, a village about 5 miles off, up a lateral valley, during which 5 miles you climb over 1200 feet.
From Aucun, still climbing, the road passes Marsous, winds up the hill-side away from the stream, and reaches the first pass, the Col de Soulor, thence it makes round the head waters of the Ouzan valley and round the flank of a bare hill called in that country-side “Mount Ugly,” until it reaches the point called the Col de Casteix. Here the foot passenger would naturally cross, as he might have crossed still lower down by the Col de Cortes, but for the sake of a gradient the road goes right round to the north and over the Col d’Aubisque, falling from thence in very long curves down to Eaux Bonnes. The town is not 2½ miles from the top of the col in a straight line. It is more than 5 by the long zigzags of the road.
From Eaux Bonnes a road of less than 3 miles takes one down the Pyrenees to Laruns in the valley, and here the great lateral road of the high Pyrenees may be said to end.
One may go to Pau the same night, but, sleeping at Eaux Bonnes, it is a most interesting journey to continue down the valley of the Gave d’Ossau to Arudy and to Oloron, thence by the road through Aramits, and Tardets to Mauléon, thence by Musculdy, Larceveau, and Lacarre to St. Jean Pied-de-Port, but all that run is through the foot hills, and though one has fine views of the range from every little pass and hilltop, these last 80 or 100 miles are not of the same nature as the track I have just been describing, the chief feature of which is the presence of a good carriageway running through the very core of high and abrupt mountains. Still, anyone who has taken the lower road, as I have advised, from Bayonne to Perpignan and wishes to go back all the way to Bayonne by a higher road nearer the mountains, cannot do better than go on from Eaux Bonnes to Laruns, to Oloron, Mauléon, St. Jean Pied-de-Port, and thence down the lovely valley of the Nive to Bayonne.
So far I have described the main circular journey, west to east, and from east back again to west, which one can take in a motor car in the French Pyrenees.
To describe or to advise as to a similar journey from north to south is not so easy, because the Spanish roads are uncertain. Moreover, there is no Spanish road crossing the lateral ranges as the French one does, so that, unless one abandons the Pyrenees altogether and goes right down into the plains, a circular journey from north to south and back north again is confined to the very narrow choice between Roncesvalles, the Somport, and the new Sallent road.
