Celtic Trail West

The Celtic Trail West takes cyclists on a journey along coastal paths and riverside trails. You’ll visit seaside towns, scenic countryside and the beautiful green hills of West Wales. The Celtic Trail West is a wonderfully scenic trail with something for everyone.

On the Celtic Trail West you’ll follow coastal paths, riverside trails and quiet lanes as the route takes you on a journey of discovery through the wonderfully scenic West Wales. The Celtic Trail has historic attractions, gorgeous landscapes, coastal gems, fantastic pit-stops and much more.

Whether you’re an experienced cyclist, a family with children, or looking for a new adventure, you’ll enjoy the Celtic Trail. It has something for everyone.

The western section of the Celtic Trail hugs Pembrokeshire’s stunning coastline. Visit the stunning seaside resorts of Tenby and Saundersfoot. Explore great traffic-free coastal routes including Millennium Coastal Park, Swansea Bike Park and the Brunel Trail.

These coastal routes are threaded together by quiet and often hilly lanes through Pembrokeshire’s scenic countryside - perfect for the more experienced cyclist looking for a long-distance, challenging cycle adventure through this stunning part of Wales.

If it’s a remote cross-country route you’re after, follow Route 47 of the Celtic Trail as it winds across the Preseli Hills between Fishguard and Carmarthen. Beyond Carmarthen follow the gentler Tywi Valley past the National Botanic Gardens and onto the scenic Swiss Valley Route. This is a lovely 11-mile traffic-free section which connects to the Millennium Coastal Park.

If you’re looking to tackle stretches of the Celtic Trail over a couple of days, the route can easily be broken down into a number of daily stages, most of which are approximately 30-45 miles long. Our suggested stages for the Celtic Trail West are Fishguard to Broad Haven, Broad Haven to Laugharne, Laugharne to Kidwelly and Kidwelly to Swansea.

The route is best ridden from west to east to make use of the prevailing westerly winds. Apart from the very first stretch, from Fishguard to St David's, where you are heading almost due west and are likely to feel the wind strongly in your face, the winds should generally help you as you travel east towards Swansea. If you want to continue onto Chepstow using the Celtic Trail, then you can follow the Celtic Trail East.
