Martiñá Peak Nature · San Cristovo de Cea, Carballiño, Ourense Image of San Cristovo de Cea, not of the place itself. At 1,039 metres it is the greatest height of the concello and one of the roofs of the Serra do Faro, the divide that separates the basins of the Miño and the Ulla. A short distance away rises the peak of Alledo, of 1,011 metres. Photo: Elisardojm (CC BY-SA 4.0) What to see and do in San Cristovo de Cea
