This route was planned by komoot.
The tour is a point-to-point route, and while komoot provides the full track, specific starting points and parking can vary depending on where you choose to begin. Many cyclists opt to start in one of the charming villages in the region, such as Ansó or Urzainqui Village, where local parking options are usually available. It's advisable to check local parking regulations for your chosen starting point.
This tour is classified as 'difficult' and is designed for experienced road cyclists with very good fitness. You'll encounter significant elevation gains, with consistent gradients of 6-8% and some sections pitching up to 10-20%, or even exceeding 17% for several kilometers. Technical descents with tight switchbacks and variable road surfaces also demand concentration. It's a rigorous test, often compared to the steeper, though sometimes shorter, climbs found in the Alps.
While many roads are well-paved and smooth, you should be prepared for some segments that might be unpaved or challenging to navigate. The route traverses diverse terrain, from twisting mountain passes like Puerto de Matamachos and Collado de Argibiela, to lush valleys and alpine meadows. Always be vigilant for variable road conditions, especially on descents.
The best time to cycle the Tour of the Navarrese and Aragonese Pyrenees is typically from late spring to early autumn (May to October). During these months, the weather is generally more stable, and mountain passes are clear of snow. However, be aware that unpredictable mountain weather is always a factor, even in summer, so be prepared for sudden changes.
The route offers breathtaking and diverse scenery. You'll pass through lush green valleys, alpine meadows, and traditional Basque farmhouses. Highlights include the stunning views from View of the Peaks of Zuriza, the charming village of Ansó, and the refreshing Swimming area in the Veral River. The landscape transitions from verdant hills to more Mediterranean vistas further east, with notable balcony roads and gorges.
As this is a road cycling route, dogs are generally not suitable companions for the ride itself due to safety concerns on paved roads with traffic. If you plan to visit the region with a dog, it's best to arrange for their care while you are cycling. Always check local regulations for specific areas or accommodations if you bring a pet.
Generally, there are no specific permits or entrance fees required for road cycling through the Parque Natural de los Valles Occidentales. However, as a protected natural area, it's crucial to respect all environmental regulations, stay on marked roads, and practice leave-no-trace principles. If you plan to visit specific attractions or refuges like Zuriza refuge and campsite, they may have their own fees or rules.
Given the 'difficult' rating and unpredictable mountain weather, essential gear includes a well-maintained race bike, appropriate cycling apparel (layers are key), a helmet, gloves, and sunglasses. Carry sufficient water and nutrition, a repair kit (spare tubes, pump, multi-tool), and navigation tools. A first-aid kit, sun protection, and rain gear are also highly recommended. Don't forget your camera for the stunning views!
Yes, this route intersects with several other well-known paths. You'll find sections that overlap with the Ruta Transpirenaica en BTT (Aisa - Roncesvalles), Via Sancti Martini - Chemin de Saragosse, and the Senda Pirenaica - E31. While these are primarily hiking or mountain biking trails, their presence indicates a rich network of routes in the area, offering possibilities for extending your adventure or exploring different disciplines.
Yes, the region offers various options for refueling and accommodation. You'll pass through charming villages like Ansó and Urzainqui Village, where you can find local eateries and guesthouses. The Zuriza refuge and campsite is another option for a stop. The Navarrese Pyrenees are also known for their authentic Spanish cycling culture, including the renowned pintxos culture in Navarre, offering great opportunities for local culinary experiences.
This tour stands out for its strong association with professional cycling, as many climbs have been featured in prestigious races like the Tour de France and the Vuelta a España. It offers a less commercialized and quieter cycling experience compared to the Alps, allowing for a more authentic immersion in the Spanish Pyrenees. The blend of challenging ascents, breathtaking scenery, and rich local culture, including the famous pintxos, creates a truly memorable adventure.
