Coast Path, Wales -- With the completion of its 870-mile Coast Path in May, Wales—situated west of England on the island of Great Britain—is home to the longest continuous coastal path around a country. The route, comprising several long- and short-distance trails, meanders along rocky Irish Sea cliff tops, sandy beaches, former railway lines, and ancient footpaths. Fourteen-mile Glamorgan Heritage Coast Path traces the area’s rich Norman history (cross the stepping stones to Ogmore Castle).
