The Dare Valley is a beautiful glacial valley. It includes all of the classic features of a south Wales mining valley – a spectacular glacial cwm at the head of the valley (with peat bogs above), alder woodlands, rhos pastures, old coal tips and remodelled coal waste, conifer plantations and classic mining villages. It provides excellent examples of post-industrial biodiversity, at a variety of sites, including some of the oldest-established remediation areas for public use in South Wales. The Dare Valley Country Park was developed 35 years ago on the site of two worked out collieries in the Dare Valley, Aberdare. Part of the first phase of land reclamation took place in the wake of the terrible Aberfan mining disaster in 1966. A third of a century later, the Park now represents one of the best examples of natural regeneration and restoration in a coal spoil environment. The restoration has been due, in part, to the chemical and physical attributes of the local coal spoil which have been actively utilised in a way to promote diversity.
