The coal mines closed in the 1980s, and since then the valley has been extensively redeveloped. The culvert through which the river used to run has been blocked off and the river allowed to flow naturally. Two lakes were built and areas were set aside with weirs for canoeing. Paths and bridleways were made linking Treharris and Trelewis and the site of the former Trelewis Drift Mine was converted into the Taff Bargoed Centre with the help of a grant from the Millennium Commission, and became the Welsh International Indoor Climbing Centre. This has one of the biggest climbing walls in the United Kingdom.[2][3]
Parc Taf Bargoed is a regenerated area of parkland in Merthyr Tydfil County Borough and is a Green Flag Park. It is situated in the Taff Bargoed Valley between Trelewis, Treharris and Bedlinog. The former colliery site has been regenerated as a wildlife haven and a base for community activities. The pavilion, at the park gates, houses the warden and provides visitors with information on the history of the park and the wildlife to be found in the area. The building also provides space for community meetings and events and walking, cycling and horse riding is encouraged in the park. The Aberfan Canoe Club and the Parc Taff Bargoed Anglers Club meet here and periodically there are canoeing, kayaking and raft building activities.[4]
