Overview

On a clear day from the summits of Trum Gelli and the neighbouring Trum Pen Gwr, in this area of Southern Snowdonia, there are 360 degree mountain and sea views to be enjoyed. We shall be hoping to experience these on this work which will commence from Bryncrug. Beginning with a minor road we shall cross fields to reach Rhydyronen Station, a stop on the world famous Talyllyn Railway before making our way along the pretty valley of Nant Braich-y-Rhiw. There is a short steep scramble up a bank to reach the track which will take us gradually uphill to find an indistinct moorland path which can be boggy in places. Erosion by off road vehicles has made 2 informal 'fords' on the track which, depending on the previous days' weather, will need to be negotiated.  It is then another climb on rough moorland to the two distinct cairns of Trum Gelli which stand proudly on the ridge at 535 metres. Continuing across similar terrain we shall find the plaque dedicated to GHP Beames founder of the Mountain Ranger Service and those from the Service who fell in WW2. We shall need to carefully negotiate fences and more tussocky ground for a steep descent and then ascent to Pen Trum Gwr, the summit of which is at 512 metres. Another long steep descent over very rough ground will eventually lead us to a stony track on which we can cross the Afon Cwm-pandy before our last long ascent on the same track. It is then a pleasant grassy track that will lead us downhill to the original tarmacked track and minor road back into the village.
