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]

In Ohio, there is a gorgeous State Park that has undisturbed forests, cascading waterfalls, rugged cliffs, deep recess caves and mysterious gorges. The 2,356-acre Hocking Hills State Park is a place of adventure for nature lovers. It is embedded in Hocking State Forest and its three nature preserves includes Conkle’s Hollow. The park is divided into these five separate sections: Old Man’s Cave, Cedar Falls, Ash Cave, Cantwell Cliffs and Rock House. Hocking Hills State Park is about 3 hours away from Cuyahoga Valley National Park, the 10th most visited U.S. National Park in 2011. Both must be gorgeous in the fall season with the changing colors of autumn foliage, but we were struck by the beauty of the “greeness” at Hocking Hills. [47 Photos]
