This is a lovely woodland trail in the Gwaun Valley that you can follow to the scenic Dwfr Ddisgynfa Cwm-du cascades. The Gwaun Valley as a whole is one of Pembrokeshire Coast National Park's hidden gems.

Dwfr Ddisgynfa Cwm-du roughly translates to 'water descending in the black valley'. This is a scenic spot where the tumbling Afon Cwmau makes its way to meet the Afon Gwaun on its short journey from its source in the Preseli Hills.

This is a delightful wood in the picturesque Gwaun Valley. Trails explore the steep northern banks of the Afon Gwaun , a great option for an amble in the Fishguard region.

Walking along a road not your thing? I hear ya! But if there's one road to change your mind, this might be it. Ffordd Bedd Morris offers spectacular views across Dinas Head and Newport.

Llanychaer is a small village near a bridge crossing the Afon Gwaun. There is an abandoned church to the North of the village with a "Holy Well". There are a number of nice footpaths to follow to get to the village, following the river through Court Wood and Tre-llwyn to the East being the pick of the routes.

Can I bring my dog on hikes in Cwm Gwaun?

Dogs are generally welcome on the trails. However, the routes often pass through fields with livestock, so it is essential to keep your dog on a lead and under close control. The ancient woodlands offer fantastic, shaded walks for you and your canine companion.

Are there any good circular walks?

Most trails in the area are circular. A great option for a moderate loop is the Cwm Gwaun trail. This 7.3 km walk requires some sure-footedness but rewards you with a fantastic mix of riverside paths and woodland scenery.

Where is a good place to park for a hike?

A popular starting point is the Sychpant National Park Picnic Site. It offers parking and provides good access to several trails that explore the surrounding woodland and valley. Please note that the public toilets at this site are no longer in service.

Are there any pubs on the walking routes?

Yes, the valley is home to the famous Dyffryn Arms in Pontfaen. Known locally as 'Bessie's', this historic pub has been serving beer from a jug since 1845. It's a truly unique and highly-regarded spot to stop for a drink, offering a glimpse into the past.

How difficult are the hikes in Cwm Gwaun?

The trails are primarily rated as easy to moderate, with no technically difficult routes. There are around 11 easy and 10 moderate hikes available. The main challenge comes from some short, steep ascents and descents on uneven paths within the woodlands.

What historical or mythical sites can I see while hiking?

The valley is rich in history and legend. On your walks, you can find sites like Parc y Meirw (Field of the Dead), a row of ancient standing stones. The area also has links to the Mabinogion tales and features the remains of an Iron Age defensive enclosure in Llanychaer.

Can I see waterfalls in the Gwaun Valley?

While there are no major, named waterfalls that are primary destinations, the steep sides of the valley mean that many smaller streams tumble down through the woodlands. After rainfall, the sound of these cascades adds to the peaceful atmosphere of the trails, particularly within the forested sections.

Is the Gwaun Valley Trail suitable for walking?

Yes, while the Gwaun Valley Trail is also promoted as an idyllic cycle route, its gentle gradients make it perfectly suitable for a leisurely walk. It offers a great way to experience the serene floor of the valley. You can find more details on the cycling route at the Pembrokeshire County Council website.

What is 'Hen Galan'?

Hen Galan is the traditional Welsh New Year celebration, which is still observed in parts of the Gwaun Valley. Following the old Julian calendar, locals celebrate the new year on January 13th with unique customs, including children singing house-to-house for gifts.
