Avon Dam Reservoir Circular Walk

Avon Dam sits high on the southern fringe of Dartmoor, reached by a track that follows the River Avon upstream through a narrowing valley before the reservoir appears, held in place by a concrete dam wall with open moorland rolling away above. This 6.4 km circular loops the reservoir and extends onto surrounding moorland where granite tors and rough grass replace the contained valley below. The 293 m of elevation gain makes this a proper climb despite the modest distance, and the upper sections feel genuinely remote with wide views across southern Dartmoor. The paths are clear but the terrain is rough in places, particularly on the moorland extension.

This is a rewarding dog friendly walk for fit dogs who enjoy working ground with texture and space. The reservoir provides drinking water and the river on the approach is accessible for cooling off. The open moorland above the dam offers excellent off-lead potential in theory, though Dartmoor livestock grazing is extensive and ponies, sheep and cattle are common, so leads should be carried and used where animals are visible. The rough, uneven ground suits dogs comfortable on natural terrain rather than surfaced paths. The climb is sustained enough to tire most dogs properly, making this a good option when a short but physical outing is needed. Parking is limited at the end of the access lane.
