From Huesca, take the N-240 in the Barbastro- Lérida direction; after about 35 km. we get to the village of Angüés, we pass through it and continue a few more kms. till we get to the bridge over the river Alcanadre and cross over it, we will then find indications that direct us to the Guara Natural Park that will divert us to the right to cross over to the left in the Abiego direction. We go through this village and find a turn off to the left in the Bierge direction. After 6 kms. we will have arrived.
