Why is Tunnel des Ecouges famous?

The road, known as Route des Ecouges, runs through an impressive tunnel dug in the rock at Pont Chabert. The 500m long tunnel leads to a road hanging above a waterfall before going down vertiginously to the Isere Valley. In 2021, work was undertaken to make the electrical connections to the tunnel. Before the work, this tunnel did not have any electrical equipment, and users who use it, particularly cyclists, found themselves plunged into complete darkness. An old road, prior to the construction of the tunnel, was fenced off, like the Grands Goulets, due to the risk of rock fall. It was highly terrifying. Due to its situation, it’s currently blocked even for pedestrians and bypassed by the tunnel.

When was Les Ecouges built?

Built in 1833, this windy wild road of Les Ecouges zigzags up to the village of Rencurel, before crossing mountain pastures until the Col de Romeyère. This is not a road for people who fear heights. Of all the routes into Le Vercors, Les Ecouges is the most vertiginous and the most stunning. The builders naturally sculpted the existing lines. The road's roof is like a smooth slab with a right angle giving a geometrical effect. In addition to the magical location, the road's architecture is unique, with the slope copying that of the limestone layers. The opening of the road was bound to economic motives, to facilitate the wooden descent of Coulmes towards the valley to a foundry of cannon, which was situated in St Gervais. The road was discussed throughout the 19th century to supply wood to the cannon foundry in St Gervais. But it was finally the inhabitants of Rencurel and St Gervais that built it to promote trade with the markets in the plain. It was finished in 1883 by J Serratrice, a Rencurel entrepreneur. It improved the access used by men since Mesolithic times, followed by the Chartreuse monks of Ecouge and Italian charcoal burners.
