Conímbriga is not a town as much as it was a town; in fact, it was quite important to the Romans whose footprint still exists here.
Allow for some time to explore the museum, the only option for food or drink is in the visitor center.
Leave by way of the road that exits the site. Turn right at the first intersection, heading straight towards and underneath the highway.
Once past the highway, you will pass a series of hamlets (Valada, Atadoa, Orelhudo, Ribeira de Casconha, and Casconha) before crossing back over the highway and arriving in Cernache. Along the way, only Casconha has a bar.
