Cascadas de Oneta are a set of three cascades, short after each other, in the river Rio de Oneta. The first and most spectacular one is Cascada La Firbia, over 20 meters high. The second one is smaller and more difficult to access is a waterfall called La Ulloa or Firbia de Abajo. The last one is even more difficult to reach and is called Cascada de Maseirua. All waterfalls look very beautiful and are a visit worthwhile.
Cascadas de Oneta are located south of the village of Oneta. From Oneta it is a 2 kilometer walk to the first waterfall (30-45 minutes). There are sign on the trail and Cascada La Firbia is easy to reach. From here you have to ascend on a slippery trail to the other waterfalls: Cascada La Ulloa and Cascada La Maseirua.
Best period to visit Cascadas de Oneta is in a wed period, Late winter or early spring, although the region is famous because of the rain falling down whole the year.
