Eglwyseg and Cyrn-y-Brain (Welsh Marilyn)

A fine and varied walk amidst the impressive limestone scenery of the upper Eglywseg valley


12 November 2023

No dogs

Starting from the top of the Horseshoe Pass (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, river and a couple of stiles we ascend across fields for 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 on a rocky path through a break in the impressive limestone cliffs onto the plateau above. Note that wet limestone is slippery and care needs to be taken after rain and when crossing the stream on route.

We follow a good path north across Eglywseg Mountain to circle round above the crags of 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 conveniently paved path towards the forest. We then turn SW on a watery track to climb to the summit of Cyrn-y-Brain (Welsh Marilyn). If the weather obliges, we can make a short detour to the fine viewpoint of Sir Watkin’s Tower. We continue SW across the summit plateau, which can be muddy and boggy after rain, past the masts to meet the access road which we follow back towards the Horseshoe pass before taking a short cut directly back to the car park.

Quiet lanes, tracks, paths – some good, some rocky, wet, muddy or boggy in places
