Caerphilly Mountain Summit

Cwmcarn Forest in South Wales consists of two red graded singletrack trails and 2 DH tracks.
Both the singletrack trails contain lots of long technical climbs as well as some long flowy descents. Rocky in places and some incredible views from the top. Both trails are clearly signposted and easy to follow although do check they aren't closed for forestry works before going.

There is also loads of fire roads running throughout the woods which could be incorporated into a ride if the singletracks become too technical.

There is a bike shop, cafe and bike wash, plus pay and display car parking facilities at the bottom where all the trails join up.

Nice ascent from Crosskeys, but watch out for very overgrown pathways on the Machen side. Great views from the top!

This area is also great for some technical trail running. Plenty of footpaths meander around the hills.

Built in 1280, this castle has a fascinating life story. It is the second largest castle and grounds in UK, slightly smaller than Windsor castle. The water defenses are now home to plenty of birds and the grounds offer fantastic views of this stunning castle

A small summit above Risca. Known locally as the "Twmp" (the hump), the pimple or the nipple, due to the shape of the mound on the summit.
