Summit specific forecast

Mountain summit forecast map

The summits of each peak form a long ridge with four of the peaks forming a horseshoe shape around the head of the Taf Fechan River which flows away to the south-east. The Brecon Beacons is said to be named after the ancient practice of lighting signal fires (beacons) on mountains to warn of attacks by invaders, or more recently to commemorate public and national events such as coronations or the Millennium.

For ardent mountain climbers, the Brecon Beacons National Park is among the best that Britain has to offer. While it doesn't have some of the headline-grabbing peaks of Snowdonia or the Scottish Highlands, it fits scores of slightly smaller mountains into its relatively compact 519 square mile area. These include the area's highest peak, Pen y Fan, as well as the marginally smaller Corn Du (873 metres). Both offer rather hospitable, anvil-shaped summits to those who reach the top, with plenty of space for rest and photographs, before tackling the descent.
