Fan y Big

Fan y Big might have had its mountain status revoked in 2018 — but don't let that put you off. This is a superb peak that forms part of a classic route through the Brecons, known as the 'horse shoe' or the 'four peaks'. With stunning panoramas on a clear day and the notorious 'diving board' jutting out for those that dare, this peak is well worth bagging on runs in the area. It is also much less crowded here than on Pen y Fan.

According to mountain classification criteria, to be regarded as a mountain, a peak must be at least 2,000 feet (609.6 meters) tall and have a minimum drop between the summit and the lowest point of the mountain ridge of 98.4 feet (30 m). While Fan y Big retains its 2,351 feet (716.6 m) height, the drop has been measured at 93.4 feet (28.5 m), making it five feet (1.5 m) under what is required to retain its mountain status.
