From its source in La Garrotxa, to its mouth in the Gulf of Roses, three dams on the Fluvià River generate electricity: Esponellà, Martís and Serinyà. We recommend this easy nature trail along the Fluvià, known as “the Dam Trail”. About 5 km long, it runs through pine and holm oak forests, as well as areas of riverside vegetation. It takes walkers past two of the river’s dams.
It starts out at the entrance of Esponellà Campsite, following the trail from Esponellà to Fares along the Fluvià River. After about 15 minutes, you’ll reach the spring at La Central (water not suitable for drinking). A few metres on, the path goes uphill. Before long, you’ll reach the first dam, the Resclosa del Martís, which was built in 1910 as one of the Pla de l’Estany’s most important public works. There, you’ll also find the Font del Molí, one of the abundant springs in the Pla de Martís. If you continue along the trail, you’ll reach a fork in the road; the path to the right will take you to the final dam.
Right before the dam, you should pass a series of vegetable allotments. This is the most picturesque part of the trail, covered by a riverside forest with species like poplar, elm or willow. This is where the trail ends, but it’s also where the Nature Reserve for Wild Fauna of Illa del Fluvià or Fares begins. This is an area of great natural interest because of the great variety of flora and fauna found there.
