My first full day in Bourg St Maurice started with freshness in the air from the change that had passed through the area. The ride I’d planned was to ascend what is claimed to be the highest paved mountain pass in the Alps, the Col de l’Iseran 2770m. The climbing consists of two parts when riding from Bourg St Maurice; from Bourg St Maurice to the turn off to Tignes and from Val d’Isere to the col. A false flat section of approximately 9 km breaks up the 1955m vertical height gained over the 40km of climbing.
The lower section is pleasant enough and follows a long treed valley to the Tignes turnoff and included some semi lit tunnels through which I used a rear flashing light though was probably unnecessary.

The true climb begins at the ski resort Val d’Isere where it continues the last 15 kilometres. Nowhere is the climb particularly steep, the challenge is in continuing upwards in the thinning air.
Above Val d'Isere
All too soon it’s actually over! I was still feeling quite good, so before turning for home I continued down the steeper north side to Bonneval Sur Arc. The climb from this side really starts another 20 km further down the valley at Lanslebourg Mont Cenis, but is mostly flat and only rises 388 metres over that distance. The true ascent starts from where I’ve descended to and is 13.4km at 7.3%.
Col d'Iseran
I’m glad I continued down this side. As unlike the Val d’Isere side with the ski resort in view much of the way; the south side is protected by being part of the Parc National de la Vanoise and is breathtaking in more ways than one.

The climbing is a little steeper with sections over 10% and the Col d’Iseran time’s two took more effort and I got to the col a little worse for wear. Here there is a confectionary stand which sells the lollies for a set price of €3.50 euro per 100 grams. A bad move to give a bonking cyclist a paper bag and a scoop… €6.50 later and a sugar high got me all the way back down to Bourg St Maurice, a shower and a big plate of pasta.
