I think the reason Cwmcarn hasnt developed is the conflict with what the Scenic Drive was originaly built for.

As has been said previously there is some trully amazing riding with in 2 miles of the carpark, I grew up in Abercarn and if people took the effort to do a little bit of exploring you would never go further West.

I must be riding a different Cwmcarn. The free ride and last descent are good but the rest are too short and you always get hit by a climb after every descent.

In otherwords, the climb isnt worth the effort.

I agree the descent is not good. The climb is good in itself if you enjoy a changeling ascent or want to improve ur proper XC riding. If you just look the climb as the bit to get out of the way before going down I think CwmCarn offers very little.
