Rock UK Summit Centre
Trelewis Merthyr Tydfil CF46 6RD
When the Taff Bargoed Valley’s mines closed in the late 1980s, many of the sites were deemed too polluted for the public to enter. Since then a major regeneration project has transformed this part of the Welsh Valleys, which is now something of a hotspot for adventure sports, and its hub is the Rock UK Summit Centre, built on the site of the former Trelewis drift mine and home to a vertiginous set of climbing walls, the largest in Wales. There is also a world-class man-man caving facility, complete with waterfall, stalagmites and stalactites, and the centre also offers kayaking and canoeing sessions on the nearby lakes.
