10 Best Beaches on Anglesey (2025)

Llanddwyn Beach & Llanddwyn Island

The most romantic beach in Wales. Golden sand, a tidal island, a lighthouse, and Snowdonia as a backdrop.

Llanddwyn Beach is extraordinary. A vast sweep of golden sand leads to Llanddwyn Island — a tidal peninsula (not a true island) with ruined churches, two lighthouses, and the legend of St Dwynwen, the Welsh patron saint of lovers. Behind you, Newborough Forest's pines frame the sand. Across the water, the full Snowdonia massif lines the horizon. It's the most photogenic beach in North Wales and possibly the most romantic in Britain.

Newborough Beach (Traeth Niwbwrch)

The other end of Llanddwyn's sand — a huge, empty beach backed by dunes and Snowdonia views.

Newborough Beach is the northern continuation of Llanddwyn Beach — miles of sand that face south across the Menai Strait to Snowdonia. The beach is vast, often empty, and backed by the Newborough Warren dune system (a National Nature Reserve). Unlike the Llanddwyn end, this section is less visited and feels properly wild. The views to Snowdonia are constant and breathtaking. Red squirrels live in the nearby forest.

Trearddur Bay

Anglesey's best family beach — clean sand, calm water, and a proper seaside village behind.

Trearddur Bay is the complete family beach package on Anglesey. A sheltered horseshoe bay with clean golden sand, calm water perfect for swimming, and a village behind with cafés, restaurants, and shops. The beach faces south so it catches the sun all day. It's Anglesey's equivalent of Tenby — a proper seaside destination with everything you need in walking distance.

Aberffraw Beach (Traeth Mawr)

A vast, empty beach behind an ancient village. The Snowdonia views are the best from any Anglesey beach.

Aberffraw was once the capital of the Kingdom of Gwynedd. Today its beach is one of the most impressive on Anglesey — a huge sweep of sand backed by towering dunes, with Snowdonia spread across the horizon. The river Ffraw cuts through the dunes to reach the sea, and at low tide the beach feels endless. Few tourists find their way here, making it one of the quietest major beaches in North Wales.

Rhosneigr (Traeth Crigyll)

Anglesey's surf and watersports hub — kitesurfers, paddleboarders, and beach vibes.

Rhosneigr is Anglesey's watersports capital. The beach faces southwest and catches plenty of swell, making it the island's best surf spot. Kitesurfers and paddleboarders flock here too. The village behind has a genuine surf-town vibe with cafés, restaurants, and a developing food scene. It's the most energy-filled beach on Anglesey — not peaceful, but exciting.

Benllech Beach

A sweeping east-coast bay — sheltered when the west coast is battered, with Blue Flag water.

Benllech sits on Anglesey's east coast, which means it's sheltered from the prevailing westerlies that batter the other side of the island. When beaches like Rhosneigr are windswept and wild, Benllech is often calm and sunny. The beach is Blue Flag awarded with clean sand and safe swimming. The village behind has shops, cafés, and accommodation. It's the reliable option when you need a calm beach day.

Cable Bay (Porth Trecastell)

A stunning crescent cove with turquoise water and the best sunset views on the island.

Cable Bay is a small, beautiful crescent of sand between low headlands on Anglesey's west coast. The name comes from the transatlantic telegraph cable that came ashore here. The beach is compact but stunning, with clear turquoise water on calm days that looks almost tropical. The west-facing aspect makes it the best sunset beach on Anglesey. There's a basic café at the car park.

Porth Dafarch

A sheltered cove near Holyhead with crystal-clear water and rocky swimming channels.

Porth Dafarch is a sheltered cove near Holyhead that feels like it belongs in Brittany rather than North Wales. The water clarity is exceptional — you can see the bottom at depth — and the rocky channels between small sandy coves create natural swimming lanes. The beach is popular with snorkellers and kayakers, and the coast path walks around South Stack are close by. It's the beach that Holyhead locals keep quiet about.

Red Wharf Bay (Traeth Coch)

A massive tidal bay with Britain's best beach pub. Arrive at low tide for miles of sand.

Red Wharf Bay is enormous — at low tide, the sand stretches for miles across the bay, creating a landscape that feels almost otherworldly. The beach is backed by woodland and the occasional old boathouse, giving it a timeless quality. But the real star is The Ship Inn, a pub right on the beach that serves excellent seafood with views across the bay. It might be the best pub location in North Wales.

Church Bay (Porth Swtan)

A tiny, charming cove on the north coast with a great café and genuine local character.

Church Bay is a small cove on Anglesey's north coast that's delightfully uncommercial. The beach is sandy and sheltered, the Wavecrest café above the beach is genuinely excellent (locally sourced seafood), and the whole place has a real community feel. The old swtan (a traditional thatched house) has been restored as a museum. It's the kind of place where you plan to stay an hour and end up spending the day.
