Trail to Ibón de Bernatuara from Bujaruelo

This route is considered difficult and is best suited for experienced trail runners and hikers with excellent physical fitness and alpine experience. It involves a significant and continuous elevation gain, with steep sections and challenging terrain, making it unsuitable for beginners or children.

The trail begins by crossing the historic San Nicolás de Bujaruelo Stone Bridge and then ascends steeply through a dense forest. After the forest, it opens into a valley with meadows and streams. The final ascent to the Ibón is stony and zigzagging, becoming particularly rocky just before the lake. The route consists primarily of unpaved sections and alpine terrain, with some gravel. Be aware that sections can be slippery with mud after rain, and snow may be present in late autumn and winter.

The route starts at the iconic San Nicolás de Bujaruelo Stone Bridge and Hermitage. As you gain altitude, you'll experience breathtaking natural landscapes and panoramic views. The highlight is the stunning Bernatuara Lake, a glacial lake known for its crystalline waters. From higher points, you can enjoy 360-degree views encompassing the Otal Valley, Monte Perdido, and even the Vignemale.

The trail typically starts from the Refugio de Bujaruelo. Parking is usually available in the vicinity of the refuge. It's advisable to arrive early, especially during peak seasons, as this is a popular starting point for various routes in the valley.

While the trail itself might be accessible for dogs, it's crucial to be aware of regulations within the Ordesa-Viñamala Biosphere Reserve. Dogs are generally allowed in the peripheral zones and on certain trails, but often require leashes. Always check the most current regulations for the specific area you plan to visit, especially concerning protected natural spaces.

The best time to trail run this route is generally from late spring to early autumn. During summer, it's recommended to start early in the morning due to the lack of shade along much of the route and potential for high temperatures. In late autumn and winter, snow can be present, requiring appropriate gear and alpine experience.

The Ibón de Bernatuara trail is located within the Ordesa-Viñamala Biosphere Reserve. While there are typically no general entrance fees for the biosphere reserve itself, specific regulations may apply to certain areas or activities, especially within the core zones of the adjacent Ordesa y Monte Perdido National Park. It's always best to check with local authorities or the park's official website for any current permit requirements or restrictions before your visit.

Given the trail's difficulty and alpine nature, you should bring sturdy trail running shoes with good grip, sufficient water (as there's limited shade), high-energy food, appropriate layers of clothing for changing mountain weather, sun protection, and a first-aid kit. A GPS device or a downloaded Komoot map is highly recommended for navigation, especially on later sections of the trail.
