Running across Wales at its widest point, the Celtic Trail takes in St David’s, Britain’s smallest city, the spectacular Pembrokeshire Coast National Park, dramatic castles in Haverfordwest, Pembroke and Kidwelly, the magnificent Llanelli Millennium Coastal Park and the wide sweep of Swansea Bay.

This ‘journey of discovery’ takes you along miles and miles of the most beautiful and varied scenery in South and West Wales. The Celtic Trail stretches across the entire breadth of South Wales, from the Irish Sea to the English Border, taking in the beautiful Pembrokeshire coast, the stunning rural countryside of Carmarthenshire, and the picturesque South Wales Valleys that powered the industrial revolution.

Following a mixture of traffic-free coastal paths, riverside trails, old railway lines and quiet lanes the Celtic Trail offers the opportunity to experience the diversity of Welsh culture, history and natural beauty, as well as some of Wales’ finest tourist attractions.

The Celtic Trail is made up of two routes - National Route 4 which goes via the coast and National Route 47 which is an inland route. Together they form two loops between Fishguard and Carmarthen or between Neath and Newport and offer an incredible mixture of family-friendly traffic-free paths and challenging rides to be enjoyed by all ages and fitness abilities.
