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 are waymarked and follow the River Irfon on part of its journey down from the Cambrian Mountains to the River Wye at Builth Wells.

White Bridge is a few miles from Llanwrtyd Wells which claims to be the smallest town in Britain.

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.

Walking trails

Afon Irfon Walk

1¼ miles/1.9 kilometres, easy (there and back)

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.

There are several boulders placed along the walk that you can sit on to rest awhile and enjoy the sights and sounds of the river.  

Don’t miss the big Sitka spruce trees with their crusty plate bark.

Cwm Irfon Trail

1½ miles/2.2 kilometres, moderate

The Cwm Irfon Trail is a circular trail.

It follows the same riverside path as the Afon Irfon Walk but it turns away from the river when the hard surface stops and joins a quiet forest road.

There are views of the valley and the different types of woodland from the forest road which returns to the car park. 

Accessibility information

There are no steps on either walk.
