The As Greas Trail is a twenty mile walk that is part of the much longer GR58 route in Galacia. It can be accessed from Vigo and it can be walked in one day or broken up into sections. Along the way you may see the semi-wild horses known as greas that have given their name to the walk. The route passes through valleys, forests and along the coast passing historic sites such as Neolithic dolmens and megalithic tombs. The start at Chandebrito and the end of the walk at Candean are on bus routes. The full walk takes about eight hours.
