The Cela Cavalos waterfall is fed by the crystal clear waters of the Cavadas and Cela Cavalos streams and, in addition to the striking waterfall that forms an irresistible natural pool, it also has a delightful lagoon with emerald green water hidden above the waterfall. The landscape is disarmingly beautiful! To get there, you have to walk and sometimes climb - about 3 km on the way there and 1.5 km on the way back. You are rewarded with absolute peace and an incomparable panorama, to which the ruins of the two old mills contribute.
