Bielsa, Mountain village in Huesca Province, Spain.
Bielsa sits at 1,053 meters elevation in the Spanish Pyrenees, serving as a gateway to Ordesa and Monte Perdido National Park with traditional stone architecture lining the confluence of Barrosa and Cinca rivers.
The village gained strategic importance as a border crossing point through the Bielsa tunnel opened in 1970, while its 16th-century church of La Asunción and Renaissance Town Hall reflect centuries of mountain settlement history.
Bielsa hosts Aragon's oldest and most internationally recognized carnival featuring traditional characters called tranque, onsos, domadores and madamas that have performed these ancient celebrations for generations.
The municipality offers basic accommodations and services for visitors, with the Bielsa tunnel providing direct access to France though heavy vehicle restrictions apply and weather conditions can affect winter accessibility.
This small community of 476 residents maintains one of Spain's most authentic Pyrenean carnival traditions while serving as the primary Spanish gateway to cross-border mountain tourism via its historic tunnel connection.
