Best Seaside Towns in Wales
10 Best Seaside Towns in Wales 2026: Where to Stay and What to Do
Wales has some of the finest seaside towns in Britain, from the candy-coloured harbour of Tenby to the grand Victorian promenades of Llandudno and the sheltered sailing bay of Abersoch.
Whether you are looking for a bucket-and-spade family holiday, a romantic coastal break or a town with great food and a lively atmosphere, this guide covers the ten best seaside towns in Wales for 2026 — with where to stay and what to do in each one.
1. Tenby, Pembrokeshire
Best for:
Families, first-time visitors to Wales, romantic breaks
Tenby is the jewel of the Welsh coast — a walled medieval town with three award-winning beaches, a working harbour and streets of brightly painted Georgian houses. Castle Beach, South Beach and North Beach each have their own character.
The boat trip to Caldey Island (home to a Cistercian monastery that still produces its own perfume and chocolate) is one of the best family days out in Wales. The town centre is compact and walkable, with excellent independent restaurants, ice cream shops and a strong arts scene that stays active well into autumn.
What’s on in 2026:
Tenby Fish Week returns in June, celebrating the town’s maritime heritage with harbour tours, seafood tastings and live cooking demonstrations on the quayside.
Getting there:
Tenby is on the Pembroke Dock rail line from Cardiff (approximately 2.5 hours with a change at Swansea). By road it is around 2 hours from Cardiff via the M4 and A477.
2. Llandudno, Conwy
Best for:
Families, couples, Victorian character
Wales’ largest seaside resort sits on a natural peninsula between two bays — the sweeping main promenade and the quieter West Shore. The Victorian pier, the working tramway up to the Great Orme headland, and the rows of elegant seafront hotels make Llandudno feel like a classic British seaside resort at its very best.
The Great Orme itself is extraordinary: a limestone headland with wild Kashmir goats, a Bronze Age copper mine you can tour, and a cable car to the 679-metre summit for panoramic views across to Ireland on a clear day.
What’s on in 2026:
The Great Orme Tramway celebrates its 125th anniversary in 2026, with special heritage events and a summer exhibition at the Summit Complex.
Getting there:
Llandudno Junction station is served by direct trains from Manchester (1.5 hours) and connects to the Cardiff service. By road, it is 45 minutes from Chester via the A55.

3. Barmouth, Eryri (Snowdonia)
Best for:
Families, walkers, mountain and sea scenery
Few seaside towns in Britain have a more dramatic setting than Barmouth. A long sandy beach sits at the mouth of the Mawddach estuary, backed by the mountains of Eryri (Snowdonia) in one direction and Cardigan Bay in the other.
The wooden railway bridge across the estuary is the longest in Wales and doubles as a walking and cycling route with exceptional views. Barmouth is refreshingly unpretentious and affordable, with good fish and chips, amusements and the kind of honest Welsh seaside character that is increasingly rare.
Getting there:
Barmouth is on the Cambrian Coast railway, with services from Birmingham New Street via Machynlleth. The 9-mile Mawddach Trail cycle path connects it to Dolgellau.
4. Abersoch, Llyn Peninsula
Best for:
Watersports, summer holidays, younger crowd
Abersoch has earned its reputation as the Welsh Riviera. The sheltered bay, sailing club, surf schools, paddleboard hire and row of chic restaurants and cocktail bars give it a relaxed, continental feel in summer that is unlike any other town on this list.
It is a firm favourite with families who return year after year, and the social scene around the marina and main street makes summer evenings here genuinely fun. Book accommodation as far ahead as possible — Abersoch sells out earlier than almost anywhere else in North Wales.
Getting there:
Abersoch has no rail link and requires a car. It is around 1.5 hours from Caernarfon via the A499 and approximately 4.5 hours from London.
5. Aberystwyth, Ceredigion
Best for:
Culture lovers, solo travellers, literary visitors
Aberystwyth is the cultural capital of Mid Wales — a vibrant university town on Cardigan Bay with a long promenade, a working cliff railway, ruined Norman castle and some of the best independent cafes and bookshops in the country.
In 2025, the town received UNESCO Creative Cities of Literature status, joining a global network alongside Edinburgh and Dublin. The National Library of Wales holds the finest collection of Welsh-language books and manuscripts in the world and is free to visit. The town also has one of the best farmers markets in Wales every Saturday morning.
What’s on in 2026:
A year-long UNESCO literary celebration programme includes author residencies, reading trails through the town’s historic streets, and a new annual literary festival launching in July 2026.
Getting there:
The Cambrian Main Line connects Aberystwyth to Birmingham New Street (around 3 hours via Shrewsbury). By road, it is 1 hour from Carmarthen and 2.5 hours from Cardiff.

6. Saundersfoot, Pembrokeshire
Best for:
Families, couples, coastal walking
Smaller and more relaxed than nearby Tenby, Saundersfoot sits in a natural south-facing bay with a working harbour, a sandy beach and some excellent waterfront restaurants.
The converted railway tunnel walk along the coast to Wiseman’s Bridge is one of the most unusual short walks in Wales, passing through old colliery tunnels cut directly through the cliffs. Saundersfoot makes an excellent base for exploring the wider Pembrokeshire coast — Amroth, Pendine Sands and Manorbier Castle Beach are all within 20 minutes by car.
Getting there:
Saundersfoot has its own request halt on the Tenby line. By road, it is 20 minutes from Tenby and approximately 2.5 hours from Cardiff.
7. Criccieth, Llyn Peninsula
Best for:
History, couples, peaceful breaks
Criccieth is one of the most picturesque small seaside towns in Wales — a Georgian resort presided over by a native Welsh castle on a dramatic headland above the bay. The views from the castle walls across Cardigan Bay to the mountains of Eryri are genuinely breathtaking.
The town has a handful of very good restaurants, the legendary Cadwaladers ice cream parlour (established 1927 and still the best in North Wales by most accounts), and a peaceful atmosphere ideal for a slower-paced break. The Llyn Coastal Path begins nearby for those who want to explore further on foot.
Getting there:
Criccieth is on the Cambrian Coast railway. By road it is 1 hour from Caernarfon and 3.5 hours from Birmingham.
8. Porthcawl, Bridgend
Best for:
Surfing, South Wales day trips, families
The closest seaside town to Cardiff and Swansea, Porthcawl has an honest, no-nonsense appeal that South Walians love fiercely. Rest Bay is one of the most consistent surf beaches in South Wales and has hosted international competition. The town’s funfair (one of the last remaining in Wales), the art deco Grand Pavilion and the enormous annual Elvis Festival give it real character.
Royal Porthcawl Golf Club is regarded as one of the finest links courses in Britain and has hosted multiple amateur championships. Sandy Bay and Trecco Bay caravan parks make it one of the largest holiday resort areas in Wales.
Getting there:
Porthcawl is 30 minutes from Cardiff and 20 minutes from Bridgend by car. Bridgend has frequent rail services from Cardiff (20 minutes) with buses running on to Porthcawl.
9. Harlech, Eryri
Best for:
History, golfers, wild beach walks
Harlech is dominated by one of the most dramatic UNESCO World Heritage castles in the world — a 13th-century fortress perched on a sheer rock face above an enormous beach and sand dune system that stretches for miles in both directions. Royal St David’s Golf Club sits below in the dunes, regularly ranked among the finest links courses in Wales.
The beach itself is long, wild and rarely crowded even in peak summer — a world away from the busier Pembrokeshire resorts. The town is small but has a strong artistic tradition, with Theatr Ardudwy hosting theatre and music events throughout the year.
Getting there:
Harlech is on the Cambrian Coast line with services from Birmingham and Pwllheli. By road it is 45 minutes south of Porthmadog along the A496.
10. Conwy
Best for:
History, North Wales base, day trips
Conwy is one of the best-preserved medieval walled towns in Europe — a UNESCO World Heritage Site with a towering 13th-century castle, intact town walls you can walk for free, and a harbour lined with mussel boats. While not a traditional beach resort, the estuary, the nearby sands of Llandudno and easy access to Eryri (Snowdonia) make it one of the most useful and atmospheric bases in North Wales.
The smallest house in Great Britain — all 72 inches of it — is a well-loved curiosity on the quayside. The town also has some excellent independent restaurants and a strong local food scene centred on local mussels and Welsh lamb.
Getting there:
Conwy has a rail station with direct services from Manchester (1.5 hours). By road it is just off the A55 North Wales expressway, 45 minutes from Chester.
