St Illtyd's Walk

60 miles (96 km)

A religous walk from Pembrey Country Park (Carmarthenshire) to Margam Country Park (Neath). The path runs through Hendry, Pontardawe and Bryn. You will visit Penlle'r Castell ruin on the summit of Mynydd y Betws (with fabulous views), the spectacular Melincourt Falls on the Neath River and the Vale of Neath. There are also splendid views of the Black Mountains and peaceful wooded sections near Abercregan. The two splendid country parks at either end of the walk are also real highlights on this challenging walk.
Near Swansea the route also skirts the edge of the wonderful Cwm Clydach National Nature Reserve.
It's worth taking a small detour from the route to explore the reserve with it's woodland, wildlife, rivers and waterfalls.
The walk is waymarked with a white and yellow disc.

Further Information and Other Local Ideas

At the end of the route in Margam you could follow a footpath north to visit Brombil Reservoir. The picturesque turquiose coloured lake is a lovely place for a peaceful stroll. From the hills surrounding the lake there are fine views to the coast too. You can find the site just a mile north of the route end point in Margam Country Park.

A ruin on Mynydd Nant-y-Bar - - 352239

A ruin on Mynydd Nant-y-Bar. This ruin is in the middle of Forestry Commission land. Locals believe it to be the remains of an old farm that predates the forestry land. The path seen passing the ruin to the right is part of St. Illtyd's Walk footpath. Unusually, a solitary Monkey Puzzle tree (Araucaria araucana) stands in what would have been the building's front garden.

Sheep on a forestry commission road - - 773738

Sheep on a forestry commission road The road sign is to let forestry traffic know that one of the numerous mountain bike paths crosses the track ahead. These bike-only tracks don't appear on any Ordnance Survey map but form one of the best mountain bike networks in the world. The bike in the sign is obviously an outline of a mountain bike. This track also forms part of the St. Illtyd's Way walk.

Meeting of the ways - - 1020272

Meeting of the ways A series of options here, depending on your mode of transport. This intricate arrangement has been put in to allow horse riders and cyclists to use the bridleway, the Cefn Ffordd track that we are standing on, but prevent use by scramblers. The bridleway continues along either the road or the track ahead. The road is the exit for vehicles from the Ffynnon Oer wind farm behind us, and was presumably the route for construction vehicles about 3 or 4 years ago. The road and the adjacent track are a dog-leg in the Coed Morgannwg Way. The St Illtyd's Walk also comes up the track we are standing on, and goes off on the track to the right.
