At the heart of Picos de Europa National Park in northern Spain, an adventure awaits hikers. The trail consists of 9 miles along the Cares River and the Cares Gorge, aka “divine gorge.” Steep cliffs stretch up over 6,500 ft (2,000 m) on one side and the Cares River is as far as 650 feet (200 m) below in the deep gorge. The Cares Gorge trail is extremely popular because it is considered one of the most beautiful walks in all of Spain. The footpath was improved about 60 years ago when tunnels were carved into the mountain to serve as a maintenance trail to a hydroelectric power station. Long ago, some sections of the path were used by shepherds, sheep and even goats; the route provided the only communication between 2 villages when it was snowy. The national park was also named a biosphere reserve by UNESCO. If you visit Spain, you might want to reserve a day to trek this beautiful trail. [38 Photos]
