Herons Rest Marina sits on the Monmouthshire and Brecon Canal near Llangattock, within or along the border of the Brecon Beacons National Park.

The location offers views toward the Sugar Loaf and surrounding upland scenery, placing it in one of the more picturesque stretches of this 33-mile canal.

The marina provides secure permanent and visitor moorings and is home to Cooper Marine, an on-site boat maintenance service offering engine work, blacking, painting, gas, heating, plumbing, electrical systems, welding, and boat safety examinations.
