A FREE guided walk led by the volunteers of the Blaenavon World Heritage Environment Group (BWHEG).
The mountain is sometimes written as Coety (Welsh) but is commonly written as Coity (English) on maps.
A strenuous walk of about 10 km (6 miles), following old mine roads, hill tracks and former railways.
After following the line of the restored Blaenavon Railway to the Whistle pub, we climb Coety Mountain. Eventually we descend via an old mine railway track skirting Mynydd Farteg Fach, and return to the World Heritage Centre once more via the Sustrans cycle track.
Some parts can be muddy in wet weather, and the walk can be exposed, so appropriate footwear and clothing are needed.
Refreshments are also advisable.
