Trail of el Cares Activity · Cabrales, Oriente, Asturias A path of about twelve kilometres hanging above the Cares gorge between Poncebos and Caín, already in León; it began as a service path for the canal that the Sociedad Eléctrica de Viesgo opened between 1915 and 1921 and was made into a trail around 1945. It is part of the Picos de Europa national park and is the busiest hiking route in the whole Cantabrian mountain range, with about 300,000 visitors a year; it runs at mid-height, carved into almost vertical walls of grey limestone, a stretch known as the divine gorge. It is usually walked there and back in a day, in 6 to 8 hours of walking; it presents no technical difficulty, but it is advisable to bring water and food, as it is an arid and hot place in summer with no resting points.
