While the Col de Nabails is renowned for cycling, hikers can find rewarding trails. A popular option is to follow the track from Pedehourat or through the forest from Arthez d'Asson to reach the pass. From the pass, you can continue along the track to reach the Pic du Merdanson, which offers further panoramic views. These routes provide a mix of forest paths and open tracks.
For beginners, the approach from Arthez d'Asson through the forest offers a more gradual introduction to the area's terrain. While the main routes to the Col involve some ascent, focusing on shorter sections or out-and-back walks to the viewpoint overlooking the plain and Arthez d'Asson can be a good starting point before tackling longer or more challenging trails.
The Col de Nabails (or Labbays) is a challenging climb for cyclists. From Lourdios, it's a significant ascent of 16.1 km with over 1,000 meters of vertical gain and an average gradient of 6.3%. Another approach from Bedous via Col de Bouésou is longer at 19.9 km, with 1,110 meters of ascent and an average gradient of 5.6%. Both routes feature varied gradients, with steep sections alternating with flatter parts, making them engaging but demanding.
Parking is typically available at the start points of the various approaches, such as in villages like Arette, Bedous, or Lourdios for cyclists, or near Pedehourat or Arthez d'Asson for hikers. It's advisable to arrive early, especially during peak season, as spaces can fill up. Public transport options directly to the Col are limited; access is generally by private vehicle or bicycle.
The suitability for families depends on the age and experience of the children. While the main cycling routes are challenging, some of the hiking tracks, particularly the forest paths from Arthez d'Asson, might be manageable for older children who are accustomed to walking. For younger children, shorter, less strenuous walks to the initial viewpoints are recommended, rather than attempting the full ascent to the pass or Pic du Merdanson.
Generally, dogs are welcome on the hiking trails in the Pyrenees, including those around Col de Nabails. However, it's crucial to keep them on a leash, especially in areas where livestock may be present or during nesting seasons for local wildlife. Always ensure you carry water for your dog and clean up after them to preserve the natural environment.
Winter conditions at Col de Nabails can be severe, with snow and ice making many routes impassable or extremely challenging. While the warmer months are generally recommended for visiting, winter can offer a different, more serene experience for experienced winter hikers or snowshoers, provided conditions are safe and appropriate gear is used. Road access may also be restricted due to snow.
Beyond the pass itself, a notable viewpoint offers stunning vistas overlooking the plain and the village of Arthez d'Asson. For those continuing their journey, the Pic du Merdanson provides even more expansive panoramic views. The routes also feature impressive rock walls in narrow valleys and serene forested sections, offering diverse natural beauty throughout the ascent.
The Col de Nabails itself is a mountain pass and does not have direct amenities like cafes, pubs, or accommodation. Visitors will need to find these services in the nearby villages such as Arette, Bedous, or Lourdios, which are located at the base of the various approaches to the pass. These villages offer a range of options for dining and lodging.
The terrain leading to Col de Nabails is remarkably varied, preventing monotony. Cyclists and hikers will experience narrow valleys flanked by impressive rock walls, followed by ascents through dense forests. The gradient is not consistent; you'll encounter steep sections interspersed with flatter or even slightly downhill stretches before rising steeply again, particularly in the initial kilometers of the climb.
Absolutely. The Col de Nabails is strategically located near other significant Pyrenean passes. Many visitors choose to combine their trip with visits to nearby cols like Col de Soudet and Col de la Pierre Saint-Martin, which are known for their spectacular panoramic views. This allows for a more comprehensive exploration of the stunning Pyrenean landscape and its diverse routes.
