A Brecon Beacons attraction has been closed to the public because of safety concerns.

Scwd yr Eira waterfall in the upper Neath Valley has been fenced off because of unstable rocks above it. 160,000 people visit the falls every year.

Health and safety officers were alerted to the potential danger by the Forestry Commission, which owns the land around the waterfall. The commission says it needs to talk to the Brecon Beacons National Park Authority and the Countryside Council for Wales. It has applied to the authority for an emergency closure order.

Restoring the site will be complicated because the area is both a Site of Special Scientific Interest and a Special Area of Conservation.

The closure order will apply to the path behind the waterfall, which enables visitors to walk behind the cascade, where the river Hepste falls into a pool.
