Snowdon's trails make the summit accessible to hikers of all abilities. The park also contains rivers, lakes, waterfalls, forests, moorlands, glacial valleys, a lovely coastline and ancient burial chambers. There's also Roman forts, World Heritage listed Norman castles, steam railways and relics of the country's mining heritage.
The 300km (186mi) Pembrokeshire Coast Path - a classic walking trail - runs along a coast riddled with rugged cliffs, sandy beaches, rocky coves and fishing villages. Inland, the historic Preseli Hills hide ancient trade routes, hill forts and burial chambers. And no one should miss St David's, where the superb, secreted cathedral marks Wales' holiest place.
Virtually all of Pembrokeshire's 290km (180mi) coastline and its offshore island are included in the national park. The islands of Skomer, Skokholm and Grassholm are inhabited by massive colonies of breeding sea birds. The area is an activity-lover's paradise, with a plethora of hiking, pony trekking, surfing, windsurfing, kayaking and fishing opportunities.
