Located in the Duranguesado region, the town of Ermua is known for its rich history and its beautiful natural landscape. Here you can enjoy the local gastronomy. The town's name may come from the Basque term Emuas, which means border area or terrain, due to its location on the dividing line between the provinces of Vizcaya and Guipúzcoa.

From the dam you have beautiful views in both directions. Looking at the lake and the mountains behind it is very nice, but looking into the small valley is also nice.
