Creigiau Gleision (Welsh Marilyn)

A rarely walked route over Creigiau Gleison, a Welsh Marilyn, involving initially vague paths over boggy ground then heather to reach a rocky summit with fine views all around towards the highest peaks of Snowdonia. A ridge walk followed by a descent through woodland and a good striding path completes the day.

No dogs allowed

From the car park we set off north along the road for a kilometre then pick a track still heading north, vague at times and over boggy, tussocky ground for a further 2km gaining height gradually. Gaiters are recommended !

Turning east we embark on a kilometre of rising ground with no path over awkward heather then grass tussock mounds which will be very tiring. As we reach the start of the main ridge of Creigiau Gleison the walking is much easier and some easy scrambling without exposure brings us to the summit at 678m. Weather dependant this is an excellent view point towards the Carneddau, Tryphan and Llyn Cowlyd.

Now follows an entertaining ridge walk for about a kilometre with occasional scrambling before we descend south. A track, vague at times, takes us south through woodland to the hamlet of Blaen y nant with views of Llyn Crafnant to the north.

A good track heads home south then west. After the initial 100m ascent it is a good striding track to the car park.


Ascents over rough, boggy ground with little or no path. Some easy scrambling, no exposure. Some arduous walking over heather and tussock grass.
