Start with the rule, then the beach

Choose the beach section before setting out

Anglesey’s Council-controlled beach areas run from 1 May to 30 September. A beach name can include both a controlled and a permitted section, so use the linked Council map and entrance signs before walking onto the sand.

What “dog friendly” means here

Every card links to the source for its rule and access details. A beach can be dog friendly only in a named part. A beach can be dog friendly only in a named section, and a foot-access cove can have livestock or steep-path conditions that matter as much as the sand rule.

Three village beaches where the summer dog choice is a specific Council-mapped section, not the broad beach name.

Cemaes, North Anglesey

Cemaes Bay

Best for: A summer visit when you can use either the small western beach or the far end of the main bay.

The useful short answers

Questions about dog-friendly Anglesey beaches

Which Anglesey beaches have summer dog controls?

Anglesey Council controls named areas at Beaumaris, Benllech, Cemaes Bay, Llanddona, Llanddwyn, Porth Dafarch and Trearddur Bay from 1 May to 30 September. The cards name the usable mapped section, or Porth Dafarch’s whole-cove seasonal ban.

Can I use a beach name alone to find the summer dog area?

No. A named beach can include both a restricted section and a dog section. Use the Council map linked from each card and the signs at the entrance. Benllech’s green route, for example, runs along the promenade edge to the southern sand.

Where do Anglesey promenade lead rules apply?

Dogs must be on leads on the promenades at Benllech, Cemaes Bay and Trearddur Bay. That rule is separate from the seasonal rules for the sand.

What should I plan for at Newborough and Penmon?

At Newborough, use Beach car park and follow both the seasonal dog signs and separate reserve signs if heading to Ynys Llanddwyn. Penmon Point is a rocky wildlife shore, so keep dogs away from seals and seabirds and take care on slippery ground.
