At 2770m, this is higher than the Galibier, not as well known, but equally beautiful. Oddly, whereas the best part of the Galibier, for scenery, is at the top, on the Isersan it’s the other way round. Approaching the main climb, in the lower valley, there were fantastic views of the remaining glaciers, hanging over the cliffs. Then a climb up a magnificent high valley, with alpine pastures, cows, and a big, glacier-fed river running down the middle. The summit was a bit of an anticlimax, an arid landscape with a big car park and restricted views. Oh well! The descent was the fastest yet, and I was glad of my touring bike wheels on the rough surface.
