Overview

Pen y Gadair Fawr

Pen y Gadair Fawr may not be the tallest in the Brecon Beacons, but it certainly holds its own with splendid views and picturesque trails. Standing at 799 metres, it draws hiking enthusiasts keen to explore its unique terrain.

Geology

The mountain is primarily fashioned from Old Red Sandstone, forming both rugged cliffs and smooth grassy inclines. It is this ancient geology that provides a sense of stability and beauty, perfect for those who enjoy exploring the past while keeping their feet on solid ground.

Routes

There are a couple of standout routes for reaching the summit:

  1. A470 and Llanwenarth: A moderate trek of about 7 km, this route starts on the well-marked paths along the A470. As you ascend, expect to encounter a mixture of grassy slopes and stony paths, all while admiring views that change with your elevation.

  2. Grwyne Fawr Reservoir: A challenging route stretching around 9 km, this offers a stunning introduction to the area as you circle the reservoir before heading uphill. Not for the faint-hearted, but oh-so-rewarding!
