It’s my back garden. I’ve only ridden here and Coed y Brenin so can’t make any comparisons but it’s a great XC trail centre with technical or fast flowing singletrack downhill sections.
The Pendam is good for a quick blast. It links most of the technical sections close to the centre and Pendam lake with short fire road climbs or lakeside singletrack.
The Summit is more of the same (uses most of the Pendam trail then goes further out) with longer XC sections and a longer climb in the middle (the Leg Burner).
I’ve not done the Syfydrin as it looks to take in a heck of a lot of road. Albeit unclassified roads. It heads right back down the valley to my village then back out to the centre again. I don’t doubt that it gets up onto the uplands a little but it’s not my cup of tea. I’d rather be on a trail.
All in all, It’s a great centre with full bike cleaning facilities, a good cafe and plenty of outdoor space to relax and watch the kite feeding after a hefty ride. You’ll not be disappointed.
