A fine walk taking in the wide range of scenery around the Eglwyseg valley.

No dogs


Do not walk if you are feeling unwell. Carry your own hand sanitiser. In case of an emergency ensure you have with you a face mask and first aid pack.
Inevitably, the route will go through gates and over stiles that other people will have touched. It may have narrow sections that mean you will be passing close to other people.

We start from the top of the Horseshoe Pass where there is parking opposite the Ponderosa Café. We follow the Clwydian Way east across the hillside, down over fields and through woodland to the valley floor at Plas Yn Eglwyseg. Crossing road and river we ascend a short distance up the opposite side of the valley to meet Offa’s Dyke Path by a patch of woodland. We then head south on Offa’s Dyke for about 1km to Bryn Goleu where we climb steeply up through a break in the limestone cliffs onto the plateau above.

From here we follow a good path north across Eglywseg Mountain to join the tracks that circle round above the woods at World’s End to meet the road again above the woods. We head north following Offa’s dyke path for a short distance along the road to where it heads NW across the moor on a paved track to the forest. We then turn SW to climb to the summit of Cyrn-y-Brain and a short detour from the summit is Sir Watkin’s Tower which is a good view point in fine weather. This section can be muddy after rain. We continue SW across the (boggy) summit past the masts to the access road which we follow back towards the Horseshoe pass before taking a short cut directly back to the car.
