In 2012 Wales became the first country in the world to open a continuous waymarked path around its entire coast. Eight hundred and seventy miles from Chepstow to Chester, taking in Pembrokeshire's sea cliffs, the Llŷn Peninsula, Anglesey's beaches, and the Dee estuary.
Inland there are three national parks — Eryri (Snowdonia), the Brecon Beacons, and Pembrokeshire Coast. These hold most of Wales's serious mountain walking. The Cambrian Way crosses the country north to south along the spine Wales. Offa's Dyke follows the English border for 177 miles. And Glyndŵr's Way loops through the mid-Wales hills that most visitors never see.
