Dog-Friendly Beaches on the Isle of Anglesey: Summer Bans and Checks

We checked 7 Anglesey beaches against the council and Natural Resources Wales. The council names seven beaches with a dog ban area from 1 May to 30 September: Beaumaris, Benllech, Cemaes Bay, Llanddwyn, Llanddona, Porth Dafarch and Trearddur Bay. Dogs can still use the rest of each beach, but the council’s new dog control order is unconfirmed, so check the signs.

I want to be upfront about what this page is. The council consulted on a new dog control order, proposing the same seven seasonal bans, and the consultation closed on 31 March 2026. We could not confirm that it was adopted, though the council’s beach page still states the restrictions. The ban areas are on council map PDFs that we could not read, so we name the source on every card with the date we checked. For a swim, our guide to dog swimming spots on Anglesey covers the island’s open beaches.

The rules in short

The pattern is simple. Every ban runs from 1 May to 30 September with no time-of-day limits, and the ban covers an area of each beach, not the whole sand. Benllech, Cemaes Bay and Trearddur Bay also need a lead on the promenade. Our Anglesey area guide explains what each service covers. Councils can change their orders, so read the signs on the day.

Summer bans: 1 May to 30 September

At these beaches dogs are not allowed in the marked area in the dates shown, and are allowed outside them. If you would like someone to walk your dog while you enjoy the beach, see our guide to dog walkers on Anglesey.

Llanddwyn Beach, Newborough
Dogs not allowed from 1 May to 30 September. The council shows the ban area on a map. Natural Resources Wales says dogs are not allowed on a section of the Blue Flag beach between the main beach car park and Ynys Llanddwyn from 1 May to 30 September. It also says that from 1 April to 1 September dogs must be on a short lead and stay on formal paths across the open dune areas and Ynys Llanddwyn.

What we could not confirm

The council pages give no postcodes, so we show a Google Maps link for every beach instead, and we have left dog bins and parking out rather than guess. We could not confirm whether the 2026 dog control order was adopted or when it starts. We found no ban on the council page for Rhosneigr, Malltraeth, Moelfre, Red Wharf Bay, Lligwy, Aberffraw or Porth Swtan, and the proposed order covers fouling there rather than a ban, but we have not confirmed that nothing else applies. We also could not find lead rules on the beaches themselves, or the wording of the guide dog and assistance dog exemption on the current council page. It is worth knowing where your nearest vet is before a coastal trip. Our guide to the Gwynedd mainland coast across the Menai Strait is dog-friendly beaches in Gwynedd.

That is everything we could confirm for now, and we will update this page when the council confirms its new order.

Busy beaches can be exciting for a dog. If yours finds crowds unsettling, the Calmdogs calming bites are a complementary feed some owners keep for days out, though for ongoing anxiety it’s best to speak to your vet.
