This route was planned by komoot.
This loop is classified as a "Hard road ride" and is considered difficult. It covers 72.1 kilometers with a significant elevation gain of 1,100 meters, requiring a very good level of fitness. Expect the ride to take approximately 3 hours and 38 minutes.
The route primarily features well-paved surfaces, but be prepared for some segments that may be unpaved and difficult. In these sections, you might need to dismount and push your bike. The loop winds through the natural, forested environment of the Forêt du Cranou.
While specific parking locations are not detailed, the loop starts from Châteaulin. We recommend checking local maps or komoot's tour planner for designated parking areas in or around Châteaulin that are suitable for starting a cycling tour.
As you cycle, you'll pass by the historic Saint-Nicolas Church Port-Launay and the serene Saint-Eloy Church. The route also takes you directly through the beautiful Cranou Forest, which is a highlight in itself.
Brittany's climate is generally mild. For road cycling, the spring, summer, and early autumn months (May to October) typically offer the most pleasant weather conditions, with less rain and warmer temperatures, making it ideal for tackling this challenging route.
The Forêt du Cranou is part of the Parc naturel régional d'Armorique. Generally, there are no entrance fees for accessing the park's natural areas for activities like cycling. However, always respect local regulations, stay on marked paths, and practice leave-no-trace principles to preserve the natural environment.
This is a road cycling route. While dogs are generally allowed in natural parks, bringing a dog on a challenging 72 km road cycling loop might not be practical or safe for the animal. If you plan to bring a dog, ensure it is well-trained, on a leash, and consider if the route's length and difficulty are appropriate for your pet.
Yes, the route briefly intersects with several other paths. You'll encounter short sections of trails such as Sentier des Crêtes, Circuit de Pont an Denved, and Cœur de Bretagne, Carhaix - Le Faou. These intersections are generally minor portions of the overall loop.
Given the route's difficulty and length, we recommend bringing a well-maintained racebike, appropriate cycling attire, a helmet, plenty of water and snacks, a repair kit, and navigation tools. Some sections may be unpaved, so consider tires that can handle varied surfaces.
The route primarily passes through natural and forested areas. While Châteaulin, your starting point, will have amenities, specific cafes or refreshment stops directly on the loop are not highlighted. It's advisable to carry sufficient water and snacks for the entire 3-hour 38-minute duration.
