Mountain Weather forecast - Brecon Beacons National Park

The Brecon Beacons is a mountain range in South Wales comprising six main peaks, with the highest peak, Pen Y Fan, standing at 886m. 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 are 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. Whilst it doesn't have some of the headline-grabbing peaks of Snowdonia or the West 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, at 886 metres, as well as the marginally smaller Corn Du (873 metres). Both offer rather hospitable, anvil-shaped summits to those who reach the top, thus allowing plenty of space for rest and photographs, before tackling the descent.

These seven ranges make up Britain's most popular mountain regions. Collectively, they attract tens of millions of visitors each year and, at least for those who head out adequately prepared, offer an enjoyable trip that keeps them coming back long into the future.
