La desembocadura del r\u00edo Campiazo, frontera natural entre Arnuero y Bareyo, nos ofrece uno de los espacios naturales de mayor belleza en Cantabria.<\/p>\n\n\n\n
Desde el puente de La Venera la r\u00eda desciende sinuosa, y paralela a ella, podr\u00e1s seguir peque\u00f1as carreteras locales y sendas para disfrutar de un paisaje \u00fanico hasta su desembocadura en el mar Cant\u00e1brico formando la playa de La Arena.<\/p>\n\n\n\n
En el camino la ermita de Los M\u00e1rtires, el Pinaruco, la ruina del molino de Castellano, el bosque de encinar y finalmente los arenales y las aguas cristalinas de la Playa de La Arena.<\/p>\n\n\n\n
Desde el casco hist\u00f3rico de Isla podr\u00e1s tambi\u00e9n realizar dos sendas circulares, descendiendo hasta el molino de Castellano, si tomas direcci\u00f3n norte podr\u00e1s bajar por el borde de la r\u00eda hasta la playa de La Arena, y si tomas direcci\u00f3n sur llegar\u00e1s a la ermita de los M\u00e1rtires y puente de La Venera.<\/p>\n\n\n\n
