Llanvihangel Crucorney lies on the eastern edge of the Black Mountains in the Brecon Beacons National Park.

The sweeping hill the village sits on is a terminal moraine, deposited during the last Ice Age, that marks the maximum advance of a glacier that once flowed down the valley.

The village is surrounded by farmland with a mix of pasture, for sheep and dairy cattle grazing, and arable crops.

The area is popular with hill walkers and the long-distance trails of the Beacons Way and Offa's Dyke Path pass close by.

With a length of approximately seven miles (11 km), it was engineered by John Hodgkinson as a 3ft 6in gauge plateway, and was horse-drawn throughout.
