About this water

A Costa da Morte river falling from the Soneira country through Vimianzo to the Ría de Camariñas. The Grande is granite spate water with mixed lowland and broken middle reaches, partial canopy and exposed estuarine sections. Wild brown trout throughout; small reo (sea-trout) population running into the lower river around Camariñas from July onwards. One of the quieter Costa da Morte reo prospects.
