There are numerous villages to explore in the Green Coast , and many are usually less than a two-hour train ride from Oviedo . One of the most beautiful along the northern coastline is the town of Luarca , also known as the white town of the green coast. Lighthouses and impressive gorges shape the shoreline of this quaint town. Plenty small fishing villages are scattered around its coast, with colorful boats dotting its blue waters. The narrow, medieval streets lend Luarca an ancient, cozy feel. It s such a mellow place, nestled around an S shaped cove amidst steep cliffs. Down below, the town is split into two by a small and winding river, and weaved together by plenty of narrow bridges.
