Source de Michu walks

This hike in the Belledonne massif is a version of route no. 44130540, entitled "Le Col de la Mine de Fer et le Lac de Crop en boucle, à partir de Pré Marcel" (The Iron Mine Pass and Lake Crop loop, starting from Pré Marcel), which avoids the passage through the Bois de la Croix Blanche, where the abandoned trail, resembling an adventure course, may put some people off. This loop, starting from Pré Marcel, although shorter, covers the mountain levels, passing from forest to alpine meadows and high-altitude mineral levels, not to mention the magnificent Lac de Crop. From Pré Marcel, climb to the Refuge Jean small pass, then cross the Col de la Mine de Fer. Descend the opposite slope to Lac de Crop, then, after descending its glacial barrier, go around Montagne de Barlet to find the uphill trail and return to the Pré Marcel car park.
