Introduced to the world stage at the tour de france 2015 route presentation, Lacets de Montvernier is a series of stunning, steep and tight hairpins rising out of the maurienne valley.
Possibly the most beautiful and crazy piece of road you’ll come across, it has to be seen to be believed. It was first used in a World Tour race in 2015 when it was part of the Critérium du Dauphiné route before it starred in the first Alpine stage of Tour de France a month later. It was also used in the modified route of the Marmotte sportive in 2015.
The climb is only 4 kilometres in length to the village of Montvernier before it joins the Col de Chaussy. The tight hairpin section comes in the first 2.5 kilometres with an almost 180 degree corner every 150m.
