After a day of cultural and ethnographic activity, we'll dive right into Nature in the town of Meis, home to the rebuilt mills of Serén. Located on a spectacular site, the best way to discover them is to walk the well-known Ruta da Auga (Water Route). Following the river along the beautifully kept hiking trail and cross wooden bridges that will take you from one to another. Right in the middle of the route, stop to catch your breath in the sculptured ensemble that reconstructs the Aldea Labrega (Farmers' Village). As a kind of summary of the whole trip, before you will appear a selection of Galician architectural symbols: the granary, the laundry, the mills, the oven, the well, crosses and even a small chapel. Don't let the hike – which is a bit intense due to its slope – tire you; when you reach the summit, you'll enjoy amazing views. Once back, sit down and relax in one of the bars located along the route where you can sample a delicious corn pie.
