The wild mountain bike trails of Brechfa come highly recommended, with regular mountain bike enthusiasts raving about it. It is also gorgeous walking country with plunging and roaring rivers and tree clad hills, forest gardens and wildlife in abundance (you may even spot the illusive red squirrel which still hold on in this country).
There are two great pubs in the two villages at the start of the trails, Brechfa and Abergorlech. There is a fun playground in Abergorlech also.
If you have children there is also a Forest School happening monthly check out the Keepers Forest Facebook page for more information.
