From September 2019 parts of Cwm Rhaeadr will be closed to walkers and mountain bikers. This is because we will be felling larch trees that have become infected with a fungus called Phytophthora ramorum. For more information please contact James Tinney 07810527670.


Cwm Rhaeadr, which means “valley of the waterfall” in Welsh, is a remote woodland and picnic area situated in the upper Tywi valley in Carmarthenshire.

You can catch a glimpse of the dramatic falls on the Waterfall Walk through the woodland.

The shorter trail, which is suitable for all abilities, passes by two peaceful ponds.

There is also a mountain biking trail for experienced riders.
