This route was planned by komoot.
This trail is rated as moderate. While it covers a distance of nearly 15 km, the elevation gain is relatively gentle at around 118 meters, making it accessible for hikers with a reasonable fitness level.
The Au Long du Lac Trail is designed as a loop, starting and ending near Ambrières-les-Vallées. This allows you to experience diverse scenery without retracing your steps.
As you hike, you'll encounter beautiful sights such as the View of the River Mayenne, offering picturesque vistas. You'll also cross the impressive Viaduc de la Rosserie, a notable bridge structure.
Yes, the route shares sections with several other official trails. You'll find yourself on parts of the La Vélo Francette, Domfront / Mayenne, and the Voie Verte de La Chapelle-Anthenaise à Ambrières-les-Vallées, among others.
Yes, dogs are generally permitted on the trail. However, it's always best to keep your dog on a leash to ensure their safety and the comfort of other hikers and local wildlife.
The trail is enjoyable throughout the warmer months. Spring and autumn offer pleasant temperatures and beautiful scenery, with autumn providing particularly vibrant foliage. Summer is also great, but be prepared for potentially warmer weather.
Generally, there are no specific permits or entrance fees required to access the Au Long du Lac Trail or the Parc Naturel Régional et Géoparc Normandie-Maine. However, always check local regulations before your visit, especially for any specific activities or facilities within the park.
The trail is a loop starting from Ambrières-les-Vallées. You can typically find parking available in or near the town, close to the start of the loop. Look for designated parking areas or public spaces that allow for day parking.
The trail offers varied terrain, including sections along the Lac de Haute Mayenne and through the surrounding natural landscape. Given its moderate difficulty and location, expect a mix of well-maintained paths, possibly some unpaved sections, and gentle inclines.
While rated moderate due to its length of nearly 15 km, the relatively low elevation gain makes it manageable for beginners who are prepared for a longer walk. If you're new to hiking, ensure you have appropriate footwear and bring enough water and snacks.
For a nearly 15 km hike, we recommend bringing plenty of water, snacks, appropriate hiking shoes, sun protection (hat, sunscreen), and layers of clothing suitable for the weather. A map or GPS device is also advisable, though the route is generally well-marked.
