The Brecon Beacons

The most impressive of the three mountainous ranges in South Wales. The range consists of 4 main mountains:
 * Corn Du (873 m)
 * Pen y Fan (886 m)
 * Cribyn (795 m)
 * Fan y Bîg (719 m).

Routes
The best way to tackle these mountains is to do a horseshoe route starting from the south by Upper Neuadd reservoir and then head due west until Graig Fan Ddu is met. Continue walking north along the ridge taking in all of the mountains, returning back down to Powys along the roman road that passes between Cribyn and Fan y Bîg.

A small extension of this route can be had by walking further east after Fan y Bîg. This allows for stunning views of the range.
