Pembrey Forest, near Llanelli

What's here


Pembrey Forest is a huge pine forest which was created on sand dunes on the Carmarthenshire coast.

Our waymarked walking trail goes to the ruins of a First World War ammunition factory – the route follows old train tracks through the trees.

Pembrey is one of Britain's rare sand dune forests - the Forestry Commission planted the trees here between 1929 and 1954 as part of a programme to replace woods cut down to supply timber for the two World Wars. 

It is home to a wide variety of plants, migrant songbirds, birds of prey and butterflies - there is a colony of the grizzled skipper butterfly here and there have been sightings of the very rare marsh fritillary butterfly.

The forest is next to Pembrey Country Park (run by Carmarthenshire County Council) which has a visitor centre, café, toilets and a range of visitor facilities and leisure activities.
