Priory Mill Farm is a small campsite set alongside the River Honddu within the Brecon Beacons National Park (Bannau Brycheiniog), just ten minutes' walk from the Georgian market town of Brecon.

The farm dates back beyond the sixteenth century, and its cobbled courtyard, miller's house, and Grade II-listed corn mill create a strong sense of historical character. The river itself is designated a Site of Special Scientific Interest.

The campsite occupies a large grass area with limited pitches, giving campers plenty of space.

Its location makes it a practical base for exploring local independent shops and cafes in Brecon, stargazing within the International Dark Sky Reserve, and attending nearby festivals such as the Brecon Jazz Festival and the Hay Literary Festival.

A self-catering holiday cottage is also available on the property.
