In Erro, different themes lead to different discoveries: the landscape of Sorogain, traditional livestock marking, routes on the Camino de Santiago and historic buildings in Ardaitz and Bizkarreta-Gerendiain. You can focus your trip on nature, culture or outdoor activities, and explore these places according to your own interests.
Sorogain: valley, river and landscape
The Sorogain Valley is surrounded by emerald-green meadows, clear waters and forests such as Odiakoa. The mountains include Adi, which rises to 1,457 metres and is the highest peak in the area. The Erro River rises in Sorogain and flows 40 kilometres from there to the Irati River. Alto de Erro marks the boundary between the Atlantic climate in the west and the sub-Mediterranean climate in the east.
A special tradition marks the year in Sorogain: cattle and horses are marked in May, and sheep in September. This makes it possible to distinguish the animals on both sides of the border. Check the exact dates before your trip.
Pilgrim routes and historic places
The Camino de Santiago runs through the centre of the Valle de Erro. The Camino del Fuerte Carlista leads to a promontory where batteries of the Carlist army once stood. Its upper section follows a stretch of the Camino de Santiago and offers a viewpoint from which to observe and interpret the transition between landscapes.
In Ardaitz, architectural history meets a distinctive site in the centre of the village. The Church of San Pedro ApĂłstol is an early Gothic building dating from the early 13th century; it has a Romanesque tower and a Gothic portal. A restored Gothic fountain from the 13th century also stands near the village centre, protecting a water source.
In Bizkarreta-Gerendiain, the Church of San Pedro stands on elevated ground above the village centre. This early Gothic building dates from the early 13th century and has a Romanesque-style façade. The surviving remains of the pilgrim hospital offer evidence of another historical connection: it was once an important refuge on the Camino de Santiago, before the pilgrim hospital in Roncesvalles was established. Bizkarreta is also home to the Mugarri Tumulus, an archaeological site associated with prehistoric rituals in the dolmen sector of Auritz.
Compare activities and routes
Around Sorogain, you can go hiking, mountain biking, caving, horse riding, snowshoeing and cross-country skiing, or follow megalithic routes. The range of options extends from outdoor activities to trails with an archaeological connection. Some activities may vary by season; check which dates are suitable for the activity you have in mind.
For cycling trips, two Gran Ruta del Pirineo routes pass through different valleys and over different mountain passes. The road route crosses Puerto de Erro, runs through the Valle de Erro on quiet roads and then continues into the Valle de Arce. The gravel route comes from the Valle de Esteribar, crosses Puerto de Errea into the Valle de Erro and then continues directly into the Valle de Arce. You can distinguish between the two routes by their respective starting directions, the mountain pass they cross and their connection to the Valle de Arce.
Mycology and visitor information
The Parque MicolĂłgico Erro-Roncesvalles covers the municipalities of Erroibar/Valle de Erro, Auritz/Burguete and Orreaga/Roncesvalles. Guided nature visits are planned for 2026, during which experts will share their knowledge of mycology. If you wish, a guided visit can include a mushroom tasting at a local business. Before your trip, check whether suitable dates are available.
The mycological information centre in Bizkarreta-Gerendiain offers advice, products for foraging and personal assistance. The former residence of the Sorogain warden now serves as an inn and restaurant and houses a tourist information centre. Before visiting, it is advisable to check the current operating information for these facilities.
