Mawgan Porth has a broad sweep of sand, a stream at its southern end and space for a long walk when the tide is out. The village sits just behind the beach, making this an easy choice if you want a café stop after your walk. It is exposed to Atlantic surf, so check the conditions before letting your dog into the water.
Dog access: Year-round.
Lifeguards: Seasonal RNLI patrols; check dates before visiting.
Facilities: Parking, toilets and places to eat nearby.
This sheltered sandy cove near Trevose Head suits a shorter, quieter beach visit. You can extend the outing along the coast path, but beach facilities are limited, so bring what your dog needs.
Dog access: Year-round. The neighbouring holiday park requires dogs to be on leads on the beach between 10 am and 6 pm.
Lifeguards: No RNLI beach patrol listed.
Facilities: Limited at the beach; the holiday park is nearby.
Near Lelant and the Hayle Estuary, Porthkidney opens into an enormous stretch of sand at low tide. Dunes back the beach, while the South West Coast Path lets you continue towards Carbis Bay. Check the tide before setting off: the amount of usable beach changes dramatically.
Dog access: Year-round on the beach; observe signs on the approach.
Lifeguards: Seasonal RNLI patrols.
Facilities: Limited on the beach; parking and refreshments are available around Lelant.
These are two separate beaches near Newquay, with a worthwhile coast and common-land walk between them. Holywell has high dunes and an open sandy bay; Crantock sits beside the Gannel estuary. Both give dogs plenty of room, though the paths around West Pentire can cross grazing land.
Dog access: Year-round at both beaches.
Lifeguards: Seasonal patrols at both; check the individual beach before visiting.
Facilities: National Trust parking and toilets at the main beach access points.
Trebarwith is the beach to choose for rock pools and a dramatic low-tide walk beneath the cliffs near Tintagel. At high tide, the sand can disappear almost completely, so tide times matter more here than at most entries on this list. The nearby Port William area provides a place to pause after the walk.
Dog access: Year-round.
Lifeguards: Seasonal RNLI patrols.
Facilities: Parking and places to eat above the beach.
Mullion Cove offers a different kind of dog outing: a small harbour, coastal scenery and paths on the Lizard Peninsula, with a little beach exposed at low tide. Come for a harbour stroll and the views rather than a long run on sand.
Dog access: Year-round, with dogs on leads at the National Trust site.
Lifeguards: None.
Facilities: Car park and public toilets; the harbour is a walk from the parking area.
Gorran Haven’s sandy village beach is handy for a gentler outing, with parking and toilets close by. The harbour wall gives it a different feel from Cornwall’s open Atlantic bays, and the coast towards Dodman Point offers a longer walk if your dog still has energy after the beach.
Dog access: Year-round; check local signs for any controls on the harbour and access routes.
Lifeguards: No RNLI beach patrol listed.
Facilities: Village parking, toilets and places to eat.
Harlyn’s wide sand, dunes and rock pools make it a practical choice near Padstow, especially if your group wants a beach walk as well as time to explore the shoreline. It is also a surf beach, so give lessons and water users plenty of space.
Dog access: Year-round.
Lifeguards: Seasonal RNLI patrols.
Facilities: Nearby car park, pub and surf school.
Sennen pairs a long sandy beach with nearby cafés and surf shops. Its Atlantic setting is appealing for a walk, but plan around it if you are visiting with a dog in summer: the daytime restriction covers much of the main holiday season.
Dog access: Dogs are excluded from Sennen Beach 10 am – 6 pm, 15 May–30 September; they can visit outside those hours.
Lifeguards: RNLI patrols operate for an extended season; check current times.
Facilities: Parking, toilets, cafés and surf schools.
Watergate Bay offers a long, open-sand walk near Newquay, especially at low tide. Its size and beachfront dining make it great for a full day out, though the exposed shore and surf call for care around the water.
Dog access: Year-round.
Lifeguards: Seasonal RNLI patrols.
Facilities: Parking, toilets, cafés and restaurants.
Vault is a quieter sand-and-shingle option near Gorran Haven, reached by a walk rather than a beachfront village. Its relative lack of facilities is part of the appeal if you want space away from busier resorts. The far end is sometimes used by naturists, which is good to know before you set off.
Dog access: Year-round.
Lifeguards: None listed.
Facilities: None on the beach; bring water and take litter away.
Also called Polly Joke, this small cove sits between Holywell Bay and Crantock. A short walk from the car park brings you to sand and a stream, while the paths over West Pentire offer a longer route. Cattle can graze nearby and sometimes come onto the beach, so look for signs before letting your dog range ahead.
Dog access: Year-round.
Lifeguards: None listed.
Facilities: Car park and dog-waste bin; no beachfront cafés or toilets.
