There are two notable climbs up to Alpe d'Huez.
1st Col de Poutran and a little further on, the Lac Besson. The Col de Poutran is at 1,995m and the car park at the Lac Besson is 2,080m.
2nd Col de Sarenne, a lovely little road that can take you up to the Col at 1,989m. You will find the Col de Sarenne signposted in Alpe d'Huez, a small road that passes the altiport as it leaves the village. From Alpe d'Huez, the road quality deteriorates in places on the 200m vertical climb to the Col.
Looking south from mid-way up Alpe d'Huez to the town of Bourg d'Oisans (730 m) and the huge peaks (3,000 m) that loom over it on the other side of the valley
