Chartreuse State Forest Trail

The starting point for this mountain bike loop is conveniently located next to a parking lot in Montfermy, making access straightforward.

This 16.5 km loop is classified as a moderate mountain bike ride. While it's generally suitable for all skill levels, it does require good physical fitness due to the 340 meters of elevation gain and varied terrain. Beginners with some experience and good fitness should be fine.

The trail features varied terrain. You'll encounter mostly unpaved paths (about 12.2 km), sections with 'pierres plates' (flat stones) for about 3.25 km, and some asphalt (around 879 meters). The route navigates through valleys, involving both ascents and descents, and includes crossing the Tourdoux stream.

Along the route, you'll pass by the historic Port-Sainte-Marie Charterhouse, ride through the beautiful Sioule Gorges, and see the lovely Montfermy Waterfall. You'll also get expansive views of the volcanoes of the Chaîne des Puys and the 12th-century church in Montfermy village.

The Auvergne-Rhône-Alpes region generally offers pleasant conditions for mountain biking from spring through autumn. To best enjoy the natural beauty and avoid extreme weather, late spring (May-June) and early autumn (September-October) are often ideal, offering comfortable temperatures and vibrant scenery.
