About
The route also goes round Lake Aiguebelette and over the Col de l'Epine, although in which order will depend on where you start. Can be started from Chambéry.
Geologically, Mont Grelle is regarded as the most southerly part of the Jura Mountains; therefore, most of this tour is in the Jura, not the Alps!
Opening
From 15/03 to 30/10.
