  Mynydd Twyn-glas trail head.


From the junction between roads A467 and A472, north of the town Newbridge in southern Wales, drive road A472 1.5 km (0.9 mi) in the direction of Pontypool (east). Turn right onto the road Herbert Terrace and follow this road 700 metres (0.4 mi) to the top of the hill. Turn left and drive 1.3 km (0.8 mi) to a right curve immediately after a cattle grid. Park at the start of the gravel road running straight ahead.

Start your hike by following the gravel road east, along the power line. When you get to some buildings and telecomm masts after 2.0 km make sure you fork right. Turn left onto a wide path 130 metres later, and then fork right after another 240 metres, which will take you the last 130 metres to the summit cairn.

Descend by reversing your ascent route.

I was going to work from our Warwick office the following week and took the opportunity to take Friday off work and travelled across from Norway on Thursday night. The plan was to spend the long-ish week-end hiking in Wales, and to continue was small project of bagging the 50 most prominent Welsh mountains. I had booked a room at the Castle Hotel in Merthyr Tydfil, which turned out to be pretty lousy hotel in not-so-nice town.

The first target this Saturday was Mynydd Twyn-glas, which gave me an easy start to the week-end, and also set the standard for the week-ends weather; no visibility and strong wind, but I avoided rain. After the hike I continued towards Ysgyryd Fawr.
