Tips from the Community
Up at 1,428 meters in the Belagua Refuge is a fantastic spot to kick back after a long day of hiking. It’s been nicely updated, so you get all the cozy mountain shelter feels with modern perks like comfy beds, hot showers, and seriously good, filling food. It's a hugely popular pitstop on the GR10, GR11, and HRP, whether you're staying overnight or just pulling up a chair for a cold beer and a hot meal with awesome views over the karst rocks, it’s always a welcome sight.

Larra-Belagua is a protected natural area located in the Roncal valley, 1,026 meters above sea level. It is one of the wildest and most unique landscapes in Navarra. For cyclists, the final 9.4-kilometer climb at 6.1% gradient constitutes a first-category mountain pass that has earned a place in the history of La Vuelta a España since its debut in 2023. The asphalt in perfect condition and the absence of traffic make this ascent a unique experience, demanding a constant rhythm and rewarding the cyclist with privileged views over the Navarrese Pyrenees.

beautiful climb starting from the valley of Larrau. Count 21km but the bulk of the elevation gain starts in Saint Engrace

Without a doubt, the Col de la Piedra de Saint Martin or Pierre Saint-Martin is one of the Top 10 in the whole of the Pyrenees. Without exceeding 2000 metres of altitude, it is a very long pass, with a lot of accumulated gradient (due to the innumerable French slopes, the gradient is 1,450 metres), with very hard slopes and several kilometres above 10%, with wonderful landscapes and panoramic views and with little traffic, except for the slopes crossed by the main road (D132 in France, the NA 137 in Spain). It is a pass with many slopes; in Europe there are few other passes that have as many slopes as this one (col de Turini, Passo delle Erbe, would be comparable in number of slopes approximately). I have only climbed it by 2 slopes: (i) my first time was from Lourdios Ichère, crossing the col de Labays and the col de Soudet. Simply spectacular; (ii) I have subsequently climbed the Spanish side on several occasions, which is unique, and which starts from Belagua and crosses the Belagua cross-country ski resort to reach the mountain pass. It is also very beautiful, with a landscape and views different from the north-east side. If I had to choose one of the two, I liked the north-west side better because it is more remote, harder and in my opinion more authentic. It is also a culturally special mountain pass because the Tribute of the 3 cows takes place on its summit every 13th of July, which is considered the oldest treaty in force in Europe. So... you know... you cannot miss the opportunity to come here and enjoy this wonderful jewel of the Pyrenees!!!!

Isaba, also known as Izaba in Basque, is a picturesque village located in the Roncal Valley in the Navarrese Pyrenees, northern Spain. This charming village is known for its rich history dating back to the Middle Ages, when it was a strategic outpost for the Kingdom of Navarre. Isaba offers breathtaking scenery with lush green meadows in spring, colorful autumn leaves and snow-capped mountains in winter.

I would not recommend right now. They recently did a chip and seal so a LOT of loose gravel. I live in the area and even the road to Osse en Aspe.

We spontaneously got a place in the hut during our visit in July 2024. Nice people, very good food, well-kept rooms.
