Third stage, third country. Today we head to Andorra which, though certainly not a Pearl of the Pyrenees, is unavoidable for anyone wishing to bag the prestigious, 2407 m high Port d’Envalira. Leaving Sort, though, we first head over the Port del Cantó on a road which is rarely cycled, despite it being nice and wide and picturesque amidst the reddish-coloured, craggy surrounds. After a brief descent we're in La Seu d'Urgell, where the road to Andorra branches off. Now, we would be lying if we claimed that Andorra, the road there and the road through it were a scenic high point. Here we need to hold our nerve a little, as the bargain hunters and through-traffic make it the busiest section of the entire tour. But once we’ve got the first few kilometres of the Port d'Envalira, which begins in Andorra-la-Vella, behind us, and gone through the unsightly ski resorts, the pass becomes really lovely. And, after all, 2400 m altitude is 2400 m altitude, and there’s nowhere in the Pyrenees where you’ll cycle higher, the Envalira pass being the highest point of our tour. The long descent then soon crosses the French border and at the end of a tough day we reach Ax-les-Thermes, where we make camp for the next two nights.
