The best beaches of Anglesey and the Llŷn Peninsula, North Wales — a sweep of golden sand, clear turquoise sea and a small lighthouse on a rocky headland

The Best Beaches of Anglesey & the Llŷn Peninsula

For sheer variety of sand and sea, few places in Britain can match the north-west corner of Wales. Anglesey (Ynys Môn) and the Llŷn Peninsula sit side by side across the water from Snowdonia, each ringed with beaches — from huge dune-backed bays to tiny harbour coves with a pub on the sand. This guide picks out the best of them and tells you what each one is like, so you can choose the right beach for your day, whether you are after surf, safe swimming or somewhere quiet to walk.

Good to know: several of these beaches hold a Blue Flag or Seaside Award for clean water and good facilities, but many of the loveliest are wild and undeveloped — so bring what you need. Parking fills early on sunny summer days, the tide makes a big difference to how much sand you get, and some beaches restrict dogs on the main stretch between 1 May and 30 September. A quick check of the tide times and the beach signs goes a long way.

The best beaches on Anglesey (Ynys Môn)

Anglesey is fringed with award-winning beaches, and its sheltered coves and shallow bays make it especially good for families.

Newborough & Llanddwyn

The jewel of the south coast, Newborough Beach is a vast sweep of pale sand backed by a pine forest and dunes, with the tidal island of Ynys Llanddwyn — its lighthouse, ruined chapel and romantic legend of St Dwynwen — reaching out at one end. The views across to the Llŷn and the mountains of Eryri are magnificent. It is a wonderful place to walk, and big enough to feel peaceful even in summer.

Rhosneigr & Trearddur Bay

On the west coast, Rhosneigr is a breezy village with two sandy beaches, popular for windsurfing and kitesurfing, while Trearddur Bay near Holyhead is a horseshoe of sand and rock pools that is a long-standing family favourite, with safe swimming when conditions allow. Both have shops and cafés close to the sand.

Benllech & Red Wharf Bay

On the gentler east coast, Benllech offers a wide, easy-access beach with good facilities, and neighbouring Red Wharf Bay reveals an enormous expanse of sand at low tide — a glorious place for a walk, with a famous waterside pub to finish.

The best beaches on the Llŷn Peninsula

The Llŷn reaches out into the Irish Sea with sandy beaches on almost every side, from lively resort sands to wild, end-of-the-world coves.

Porthdinllaen & Nefyn

One of the most photographed spots in Wales, Porthdinllaen is a curve of golden sand sheltering a cluster of old cottages and the much-loved Tŷ Coch Inn, right on the beach. Reached on foot across the sand or over the headland from Morfa Nefyn, it is the picture-postcard Llŷn. The whole north coast around Nefyn is lined with sandy bays.

Abersoch & Llanbedrog

On the sheltered south side, Abersoch is the Llŷn’s sailing and watersports capital, with a busy main beach and the dune-backed Warren nearby. Just along the coast, Llanbedrog has a pretty sheltered beach famous for its row of brightly painted beach huts — one of the prettiest scenes on the peninsula.

Porthor & Hell’s Mouth

Towards the wild western tip, Porthor — the “Whistling Sands” — is famous for sand that squeaks underfoot, while the long surf beach of Hell’s Mouth (Porth Neigwl) draws surfers to its rolling Atlantic swell. These are beaches for big skies and long walks rather than ice-cream kiosks.
