The climb to the Col de l'Iseran from the north is particularly popular among cyclists for good reasons. It leads through an impressive mountain landscape to the highest pass in Europe. Motorized traffic is not too dense and the ascent is not really steep (half of the 500 meter intervals slopes 6 or 7%). Therefore, also the less experienced cyclist may cope with this climb and with 614 climb effort points (cep) it is much easier than the ascent to the Iséran from the south side (828 cep), which I find more beautiful, though. On the north side the ski lift facilities are somewhat disturbing. The ride begins at the roundabout in the center of Val d'Isère and leads without side street and with just a few curves to the pass. Nowhere the road gets really steep with a steepest 500-meter interval of 9%. One could also start this tour with the climb from Bourg-Saint-Maurice to Val d'Isère. This would result in 31 kilometers and more than 1,000 elevation meters extra but also a lot of discomfort with traffic on a wide street and danger in some unpleasant tunnels. I didn't add this approach to the ride.
