An authentic and unmissable refuge where we stopped during our mountain bike crossing of the Assietta with my friend. Two incredible days filled with the beauty of the surroundings and exceptional autumn light. One night at 2500m altitude at the Casa Assietta refuge, where we were welcomed like royalty by Roberto! A good night's sleep under the covers after the host had prepared an excellent dinner for us! Thank you, Roberto!

From Colle dell'Assietta, you climb 1.5 km of rougher dirt road to Gran Serin, and from there you descend towards the barracks. It's an incredible place, thinking about how these structures were built. The road down to Frais is particularly rough, and the gravel is very difficult to navigate, but the views over the valley are breathtaking (if it weren't for the highway viaducts that block the view at the bottom of the valley).

Gastronomia del Colle is the best place to stop before climbing. Sandwiches (delicious, freshly made on the spot), coffee, soft drinks, and cheeses are always top-notch. A must-see now.

The best time to ride the no-traffic gravel trails in Chiomonte is typically from late spring to early autumn (May to October). During these months, the high-altitude routes are generally free of snow, and the weather is more stable. Always check local conditions, especially for routes like the Strada dell'Assietta, which can be affected by snow well into early summer.
The routes listed in this guide are generally rated as 'difficult' due to significant elevation and technical sections, making them less suitable for young children or beginner riders. For family-friendly options, it's advisable to look for easier, shorter routes in the lower parts of the Susa Valley or consider paved cycle paths.
Many routes offer spectacular views and pass by significant landmarks. You might encounter historical sites like Fort Gran Serin or pass through high mountain passes such as Blegier Pass.

Parking availability varies by starting point. For routes like the Strada dell'Assietta – Colle dell'Assietta loop from Susa, you can often find parking in larger towns like Susa. For routes starting in smaller hamlets or at higher altitudes, look for designated parking areas or consult local maps for suitable spots before your ride.
While the high-altitude, no-traffic routes offer remote experiences, you'll find opportunities for refreshments in the towns and villages at the start or end of your ride, such as Chiomonte or Susa.
