Heddon’s Mouth Trail
Devon
Heddon's Mouth Trail follows the River Heddon through a steep-sided wooded valley down to the dramatic North Devon coast, where the river meets the sea between towering cliffs. This 3.2 km out-and-back route descends 256 metres through beautiful mixed woodland before emerging at the rocky cove of Heddon's Mouth, where the landscape opens up to crashing waves and salt air. The combination of sheltered riverside woodland and exposed coastline packs remarkable variety into a short distance. The well-maintained path makes the descent straightforward, though the climb back requires steady effort.
This dog friendly walk is superb for dogs who enjoy both woodland and coast. The high off-lead potential and low livestock risk make it one of the most relaxed walks on this stretch of Devon coast. The River Heddon provides water access throughout the descent, and the rocky cove at the bottom is a brilliant spot for exploration. Dogs respond immediately to the transition from sheltered forest to open sea air, and the varied terrain — soft woodland floor, riverside rocks, coastal shingle — keeps noses and paws busy throughout. The climb back up provides good exercise without being punishing.
