Outstanding trails, very well maintained despite no cost to use them. Plenty of variety and very suitable for beginners. Lots of trail intersections so you can vary your ride.
Trails always seem to be looked after - fallen branches quickly removed, etc. Some of the trails would not be out of place at a bike park.
I can't think of any, Brechfa is my favourite trail center.
