Very helpful staff who kindly refilled our water bottles - also pointed out that on entering the main carpark there is a public tap next to the unit/toilets on the left.

Part of the extreme-rated Y Mynydd DH track, there are two options at 'Road Gap': a large drop off the road, or a rocky roll down great slabs into a berm. The choice is yours, but neither look particularly easy!

My favourite sector of the Pedalhounds DH track, head into the woodlands for some steeper trails down this hill cleave with plenty of features along the way. The first is a drop over a log into a left-hand corner, before a series of steeper swoops. Then there's a tricky left hander (again with roots, of course) into a larger drop, before some more fantastic corners, roots and another, even larger drop. The drops have great, downhill landings but the final few are not rollable.

The downhill section of the blue-rated Pwca trail, this trail links together right hairpin berms with endless rollers and catch berms that'll keep you on your toes. Great for beginners and more experienced riders alike with the potential to double some of the rollers or jump off the rock slabs that occasionally line the trail. Enjoy the descent that's like one enormous pump track!

Swoop through two tunnels under the Y Mynydd downhill track as you take the blue Pwca singletrack. These are well constructed but look out for puddles as they can get a bit mucky!

If you'd like to follow the blue-rated Pwca trail, this is the point where it peels off to the right, leaving the red-rated Cafall and Twrch trails. It's well signposted and you have to stop here to go through the stone wall circle, which also leads onto footpaths and a play area.
