The Siurana reservoir holds the waters coming from river Siurana, the main afluent of the Ebro in  the region of Tarragona.

It’s quiet waters are a great place to go kayaking and canoeing.

It is surrounded by the Montsant mountain range  and  on the peak of a cliff rock where you have lots of well known climbing routes you’ll find the remains of the village of Siurana.
