Cwmsymlog & Llyn Rhosgoch Cicular. (4 miles)


We will be meeting by St Peter’s at 9:00am then driving to the car park at Llyn Pendam above Penrhyncoch. The walk is easy to follow, being mostly along tracks.

Cwmsymlog is a very ancient mine. It was worked in the mid 18th century and was described by Lewis Morris as ‘the richest in Lead and Silver of any of his Majesty’s Dominions’ (Bick 1988, 19). From the 1620s, under Sir Hugh Myddelton, the mine and community developed, and a chapel was built to serve the mineworkers.

A Cornish engine was installed in 1840, but by then the reserves were virtually exhausted, and the mine closed soon after. It was, however, reopened in 1850 as East Darren Mine and worked successfully until 1882. Subsequently several attempts were made to reopen workings, but mining finally ceased in 1901. Estate maps show the mine workings at Cwmsymlog with a scattering of dispersed cottages, each with an enclosed small field or garden.

The valley sides are shown as unenclosed moorland. The settlement went into decline in the 20th century, and cottages and houses were abandoned.


There has been a recent revival of fortunes, with houses having been renovated and new ones constructed.  The ventilation chimney stack has been reconstructed and in part preserved which sits there proudly today.
