This town has most services, including many atms and friendly locals.
The way out of town, if you spent the night in the hostal, is "behind" the hostal. Walk around the building to your Left. Follow that road and keep to the right when it splits. Follow the arrows and the signs pointing to Quereño.
An alternate route of equal distance can be made by following the OU-536 to O Barco on the South side of the river Sil. The northern trail (described on the next waypoint) is the preferred trail.
