Alnmouth Coastal Walk
Northumberland
Alnmouth sits where the River Aln meets the Northumberland coast, and this 8 km circular makes the most of both settings. The route heads south along the beach before climbing onto low coastal cliffs with views up to Dunstanburgh and beyond, then loops inland through dune grassland and back along the estuary where wading birds feed on the mudflats at low tide. The village itself is handsome and compact, with a handful of pubs and cafes that welcome dogs. The terrain is gentle throughout, with only 85 m of total climbing, making this an easy but never dull half-day out.
Dogs thrive on this dog friendly walk thanks to the constant change of surface and scent. The beach section offers open sand running and sea access, while the estuary stretch is rich with bird scent and tidal smells that keep noses working. Off-lead potential is high across most of the route, with livestock unlikely on the coastal sections. The dune paths are soft underfoot and sheltered from wind, providing a good option on blustery days when the exposed beach feels too much. The whole route stays accessible year-round and suits dogs of any size or fitness level.
