This route was planned by komoot.
The trail traverses a dramatic geological fault, forming a narrow, 70-meter deep gorge carved through a rocky ridge. You'll encounter large rock blocks, the Sonce river, a waterfall, and an artificial pond. From the heights of the gorge, enjoy superb panoramic views, including a Calvary marking the highest point. The landscape is a rich mosaic of natural environments, featuring woodland, moorland, scree, and peat bogs.
Yes, the trail is generally considered a moderate hike, but it features easily-accessible paths suitable for most skill levels. While it requires good fitness, its diverse terrain and manageable length make it enjoyable for families and those new to hiking. The komoot tour is 8.6 km long with 130m of elevation gain.
Beyond the stunning gorge itself, key points of interest include the legendary Fosse Arthour, with its caves said to be King Arthur and Queen Guinevere's chambers. You'll also pass the Gué Saffray quarry, a waterfall, a natural basin rumored to be bottomless, and a Calvary offering panoramic views from the ridge. There's also an inn on-site for refreshments.
Specific parking information is not detailed in the provided sources, but given its popularity, there is likely designated parking near the trailhead. It's advisable to check local signage or online maps for the most convenient parking areas when planning your visit to the La Fosse Arthour loop.
The trail can be enjoyed year-round, but spring and autumn offer particularly pleasant conditions with mild temperatures and vibrant foliage. Summer is also popular, though it can be warmer. Winter hikes are possible, but be mindful of potentially slippery conditions, especially in the gorge.
While the sources don't explicitly state dog-friendliness, many trails in regional natural parks in France allow dogs on a leash. Given the diverse terrain and potential for wildlife, it's recommended to keep dogs on a leash at all times to ensure their safety and respect for the natural environment. Always check local regulations before you go.
Generally, access to trails within French Regional Natural Parks, including the Parc Naturel Régional et Géoparc Normandie-Maine, is free and does not require a permit. However, always respect local regulations, especially concerning protected areas, and be mindful of any specific rules posted at the trailhead.
Yes, the route also passes through sections of the de Bagnoles-de-l'Orne à Saint-Pois, Chemin des Arpents, Chemin de la Carrière, Chemin de Guenièvre, Chemin de la Poterie, and Chemin des Gîtes.
Yes, there is an inn located on-site at La Fosse Arthour, offering a convenient place to rest and eat after your hike. For more options, nearby towns within the Parc Naturel Régional et Géoparc Normandie-Maine would provide additional restaurants and accommodations.
The site is steeped in the legend of King Arthur. Two caves within the rocks are said to be the chambers of King Arthur and Queen Guinevere. Local lore suggests they lived separately, only meeting after sunset. One tragic tale recounts Arthur's impatience leading to his fall into the ravine, followed by Guinevere throwing herself in. The Sonce river's natural basin at the gorge's base is also said to be bottomless and possess magical properties granted by King Arthur.
Given the moderate difficulty and varied terrain, it's advisable to wear sturdy hiking shoes. Bring water, snacks, and appropriate clothing layers for changing weather conditions. A camera is recommended for the panoramic views and unique geological features. If you plan to explore the caves or rocky areas, a headlamp might be useful.
70m below me lies the gorge that the Sonce dug in the rocks. Arthour and Guinevere are said to have fallen down here "anno dunnemal". That's why the gorge got its name.
The last section is not very passable, due to tree felling... Forestry equipment holes
