This route was planned by komoot.
This trail is rated as difficult, primarily due to its length of approximately 22.8 kilometers (14.2 miles). While the paths are generally accessible, it requires very good fitness and can take 6 to 7 hours to complete. Sturdy shoes are highly recommended.
The terrain is quite varied. You'll encounter a mix of mountain hiking trails, regular paths, and some sections on roads. Within the Parc Naturel Régional d'Armorique, expect rugged mountains, forests, heaths, and marshes. Around Lac de Brennilis, there are prairies, moorland, and peat bogs. Be prepared for potentially very muddy sections, especially after rain, and some wooden footbridges that might be in disrepair.
You'll experience diverse scenery, including the wild hills of the Monts d'Arrée, the expansive Lac de Brennilis, and the prominent Mont Saint-Michel of Brasparts. The summit of Montagne Saint-Michel offers magnificent 360-degree panoramic views. Other notable features include the Brennilis Lake Peatlands and Menez Kador.
The trail starts from Saint-Rivoal. While specific parking details aren't provided, it's generally advisable to look for designated parking areas within the village or near the start of the loop. Always check local signage for parking regulations.
Yes, the Parc Naturel Régional d'Armorique generally welcomes dogs. However, it's crucial to keep your dog on a leash, especially in areas with livestock, wildlife, or near the peat bogs and sensitive natural environments around Lac de Brennilis. Always practice Leave No Trace principles.
No, there are typically no entrance fees or permits required to hike on public trails within the Parc Naturel Régional d'Armorique. However, always respect park regulations, which focus on preserving the natural environment and local culture.
The trail can be enjoyed in various seasons, but spring and autumn often offer pleasant temperatures and beautiful scenery. Spring brings blooming heathlands, while autumn showcases vibrant foliage. Be mindful that certain sections can become very muddy, especially after heavy rain, so consider drier periods if possible.
Absolutely. The area around Lac de Brennilis, known as the Yeun Elez basin, is steeped in Breton legend, famously said to contain the 'Gates of Hell' (Youdig). The Montagne Saint-Michel was historically a site of Celtic druidic worship, and the entire Parc Naturel Régional d'Armorique is known as a 'Land of legends' with tales of Korrigans and other mythical figures.
Yes, this route intersects with several other trails. You'll find yourself on sections of the Cœur de Bretagne, Carhaix - Le Faou, Circuit des Landes et Tourbières, and Circuit pédestre du Yeun Elez for significant portions of the hike. It also briefly touches the Chemin des Monts d'Arrée and Hent Kuzh.
The summit of Mont Saint-Michel of Brasparts, at 381 meters, features a chapel and offers sweeping views. While there's a road for those with reduced mobility, the original stairs were damaged in a 2022 fire. A temporary route may be in place, so be prepared for potentially altered access to the very top.
Given its difficult rating and considerable length of nearly 23 kilometers, this loop is generally not recommended for families with young children or those seeking a leisurely stroll. It's best suited for experienced hikers with good fitness levels.
