Alnmouth Beach
The sand east of the village, running from the Aln estuary mouth south towards Buston Links, with dune paths from the top of the village. No seasonal dog ban applies here in any month. The estuary channel shifts and runs fast on the ebb, so the open beach is the better side for a dog in the water.
Alnmouth to Warkworth coast path
6.3 MI · 3H · 88% OFF-ROADSix miles of nearly unbroken sand and dune in three hours, south past Buston and Birling Links to Warkworth beach and inland to the castle. Begin at the Alnmouth dune car park and come back on the X18 bus, which runs hourly between the two villages most of the day. This is the emptiest big beach on the county’s southern coast, unrestricted all year and off-lead the whole way, with burns crossing the sand for a drink; the dune slacks are grazed in places and the last half-mile follows the Coquet through Warkworth on lanes.
Alnmouth village and the Aln estuary
4 MI · 1H 45M · 82% OFF-ROADFour easy miles in about an hour and three quarters, along the beach below the coloured houses, round the mouth of the Aln and back beside the estuary to the village. Start from the beach car park on the dunes at the north end of Alnmouth, which is pay-and-display and modest in size; the streets themselves are largely residents-only. Alnmouth beach has no seasonal dog restriction and is off-lead sand, but the estuary mudflats are a roost for waders and the sheep-grazed dune bank between beach and river needs a lead.
