Hiking around Lake Guerlédan
Nestled in the heart of Brittany, Lake Guerlédan unfolds its 40 km of trails through its 400 hectares of water. Between wooded hills, breathtaking viewpoints, and traces of history, this hike promises a true journey into nature. Put on your hiking shoes: the lake is worth it... and it will reward you!
By choosing the Best Western Le Duguesclin in Saint-Brieuc as your base camp, you'll have easy access to this exceptional hike.
Departing from Mûr-de-Bretagne, Guerlédan Cove immediately immerses you in the wild atmosphere of the lake.
Here, the landscape sculpted by the dam reveals itself between sparkling water and wooded hills.
Following the stairs of the Departmental Outdoor Activities Center, you reach the shores and discover a magnificent view of one of the rocky spurs of the Caurel Woods.
A first panorama to warm you up.
Next, head to Landroanec, one of the most secret hiking spots.
Here, perched above the wetlands and hidden beneath the willows, you'll get up close and personal with the shoreline.
An ideal place to discreetly observe wildlife and enjoy a moment of silence.
A change of scenery awaits with Beau Rivage: a lakeside resort, its large beach invites you to relax.
It's also the starting point for speedboat rides to discover Guerlédan from the water. A perfect stopover to catch your breath between two trails.
Leaving Beau Rivage to the west, take a step back in time by exploring the Keriven Woods. This site preserves traces of the former slate quarrying industry that was at its peak in the 19th century.
A 2 km trail retraces the history of these men who descended every day to extract slate from beneath the forest's foliage.
Get ready to climb! After a steep climb, you reach Trégnanton, perched high above the lake.
Here, the steep rocks overlook Guerlédan and offer one of the most beautiful panoramas on the trail. A perfect spot for a photo break (or a well-deserved picnic).
Further on, the majestic Quénécan Forest, nicknamed "Little Breton Switzerland," will amaze you.
Spanning 3,000 hectares, its landscapes change with the seasons. Here, you'll discover the Forges stream, which marks the border between Côtes-d'Armor and Morbihan.
A final stop along the water is the Bon Repos site. The tranquility of the banks of the Nantes-Brest Canal contrasts with the elegance of the 13th-century Cistercian abbey.
A place imbued with serenity, ideal for savoring the end of your adventure around the lake.
Good to know: The complete lake tour is accessible from March 1st to mid-September. During the hunting season (September 17th to February 29th), certain sections of the shoreline are subject to restrictions.
After your workout, you'll appreciate the comfort of the rooms at the 3-star Hotel Le Duguesclin in Saint-Brieuc!
