Irfon Forest - White Bridge, near Llanwrtyd Wells

What's here


Situated in a remote part of mid Wales but easy to find, White Bridge car park and riverside picnic area is the starting point for two short walking trails in Irfon Forest.

Both trails follow the River Irfon on part of its journey down from the Cambrian Mountains to the River Wye at Builth Wells.

Don’t miss the Wash Pool back down the road towards Llanwrtyd Wells, where farmers once washed their sheep before shearing them.

The cascades above the pool can be dramatic after a lot of rain.

The walking trails are waymarked from start to finish.

The Afon Irfon Walk follows a riverside path along the Afon Irfon and through a variety of woodlands before returning along the same path to the car park.

Cwm Irfon Trail
