Frequently asked questions
The best beaches in North Wales depend on what you are looking for. For families with young children: Benllech on Anglesey (Blue Flag, safe shallow water, car park adjacent) and Llandudno North Shore (traditional seaside, pier, facilities). For wild and romantic beaches: Porth Dinllaen on the Llŷn Peninsula (car-free, only accessible on foot, with the Tŷ Coch Inn on the sand) and Newborough on Anglesey (vast dunes, walk through the forest to reach it, Llanddwyn Island accessible at low tide). For swimming: Abersoch on the Llŷn (sheltered, warm, sailing village character) and Trearddur Bay on Anglesey (clear, sheltered water).
The safest beaches for swimming in North Wales are the sheltered bays with calm water: Benllech and Red Wharf Bay on Anglesey, Abersoch on the Llŷn Peninsula, and Llandudno North Shore. Avoid swimming from tidal estuary beaches (Barmouth, Aberdyfi, Conwy) where strong currents make swimming dangerous. The Menai Strait between Anglesey and the mainland has very strong tidal currents — swimming in the Strait itself is not recommended. The open Atlantic-facing beaches of the Llŷn Peninsula (Hell's Mouth/Porth Neigwl) can have significant swell and rip currents; experienced sea swimmers only.
Some North Wales beaches have seasonal dog restrictions (typically May to September on the main beach area). The main resort beaches with seasonal restrictions include Llandudno North Shore, Rhyl, and Prestatyn. Beaches without restrictions (dogs welcome year-round) include most Llŷn Peninsula beaches (Porth Dinllaen, Aberdaron, Hell's Mouth, Nefyn), Newborough on Anglesey (main beach), and many smaller coves on both peninsulas. Always check local beach signage on arrival as restrictions and areas can change.
Harlech Beach is a wide, dune-backed beach 4 miles long below the UNESCO castle town, managed by the National Trust. It is one of the finest and least-crowded beaches on the west Wales coast — the combination of wide sand, the castle on its 60-metre cliff behind, and the Rhinog mountains to the north creates an exceptional setting. The beach is accessed from the town by a footpath and boardwalk through the dunes. Dogs are welcome year-round. The beach faces west into Cardigan Bay and can have Atlantic swell; swimming is possible in calm conditions. The car park at Harlech beach is payable.
Black Rock Sands (Morfa Bychan) is a 2-mile beach south of Porthmadog with a distinctive feature: cars can drive directly onto the beach at low tide. This makes it one of very few drivable beaches in Wales and a family favourite for those who want to set up beach camp with the car accessible. The beach is wide and flat at low tide with views across Cardigan Bay to the Llŷn Peninsula. Dogs are welcome. The adjacent Criccieth Castle (Cadw) on its headland is visible from the beach. Parking on the beach requires the tide to be low enough — check local tide times before visiting.
Yes — Abersoch beach on the southern coast of the Llŷn Peninsula is excellent for families. The bay is sheltered, the water is warmer than the exposed Atlantic-facing beaches, and the sailing village character of the town means there are good facilities (cafés, restaurants, water sports hire). The beach can be crowded in peak summer; arrive early. Abersoch has developed a reputation as a upmarket holiday village with correspondingly priced accommodation and restaurants. The adjacent beach at Llanbedrog (4 miles west) is less crowded and in an equally beautiful setting below a wooded headland.
