Just spent a long week sport climbing in Costa Daurada. We stayed in a house (with about 32 students and ex-students) near the village of Cornudella de Montsant which was an excellent location really close to Siurana and Arboli. Absolutely brilliant climbing and although my brain wanted to stay a lot longer my body seems quite glad to have some rest.
If you like sport climbing it is definitely a recommended place. Great times.
