The 7.5-mile trail runs alongside the Cares Gorge (nicknamed the Divine Gorge) along an amazing footpath hacked out of the cliff face, at the edge of the 1,000 meter deep gorge. At times the trail is rather narrow and a bit precariously close to the edge. It is considered to be one of the most breathtaking trekking trails in all of Europe. The trail goes through Picos de Europa National Parque from the town of Poncebos in the north to Cain in the South.
