This route was planned by komoot.
This trail is rated as difficult and is best suited for experienced mountain bikers with excellent physical condition and advanced technical skills. You should be prepared for significant elevation changes, including extremely steep sections where you might need to dismount and push your bike. The descent is technical and can involve navigating dense bushes.
The terrain is highly varied, featuring steep hills, lush valleys, and expansive forests. You'll encounter singletracks, trails, and even a historical cobblestone 'medieval road' segment. Be prepared for rocky sections and potentially slippery poudingue blocks. Some parts, especially above Ascain, might involve dense vegetation and less clear paths.
The route offers breathtaking panoramic views, including tremendous vistas of the valleys and expansive views of the Pyrenees. Key highlights include the Old medieval road south of Sare, a View of the valley, Collado de Kondendia where you might spot Pottoks (semi-wild horses), and a stunning Panorama of the Pyrenees. The summit of La Rhune provides exceptional views stretching from the Atlantic Ocean to the 3000-meter peaks of the Pyrenees.
While the trail can be ridden in various seasons, consider the weather conditions carefully. Morning fog can occasionally shroud the valleys, and wet or foggy ground can make technical sections even more challenging. Spring and autumn generally offer more moderate temperatures and clearer skies, but always check the local forecast before you go.
The trail passes through natural areas where local wildlife, such as Pottoks, may be present. While dogs are generally allowed on trails in the region, it's always best to keep them on a leash to ensure their safety, respect wildlife, and comply with local regulations, especially in areas with livestock or protected species.
Specific parking information for this exact trailhead is not detailed, but Sare and Ascain are common starting points for routes in the area. Look for public parking areas within these villages, which often serve as access points for local trails. Always check local signage for parking restrictions or fees.
Generally, no specific permits or entrance fees are required to access this mountain biking trail itself, as it traverses public lands and established paths. However, if you plan to visit specific attractions or use facilities at the summit of La Rhune (like the tourist train), separate fees may apply.
Yes, the route intersects with several other trails. You'll find sections that are part of the Grande Traverséee VTT du Pays Basque, Variante 2.2, Bizkarzun, and the Ruta Transpirenaica en BTT (Roncesvalles - Hondarribia), among others. This offers opportunities to extend or modify your ride if desired.
Given the trail's difficulty and length (over 30 km and 1000m elevation gain), you should bring plenty of water, energy snacks, a repair kit for your bike, and appropriate safety gear including a helmet. Navigation tools are also highly recommended, as some sections might be less clearly marked or involve dense vegetation.
While the Boucle de Sare vers la Rhune et Ascain is a popular and iconic route, some sections, particularly those leading directly to La Rhune, can be busy. For a sense of solitude, explore other trails around Sare that might not involve the direct ascent to La Rhune's summit, or ride during off-peak times. The varied terrain of the Basque Country offers many options for different skill levels.
Attention very hard circuit with portions with non-existent paths in particular the return towards Ascin. Some fairly long portions require pushing the bike and very rough descents from the mountain lodge on the Spanish side are impassable on the bike. Not to be done without a lot of technical and physical baggage...and again, because crossing a threshold, what is the pleasure of spending a large part of the circuit next to your bike...? 😕
