Underrated Seaside Towns in Wales: Affordable Coastlines, Peaceful Escapes & Hidden Gems
Underrated seaside towns in Wales — places where time feels slower, nature feels closer, and adventures feel more personal.
When most people imagine a Welsh seaside escape, they picture the big names – Tenby, Llandudno, Rhyl, and Barry Island. Beautiful, yes… but also busy, especially during summer holidays, bank-holiday weekends, and warm spring days. But what if you’re craving something quieter? A stretch of coastline where the only crowds are drifting seabirds, the only noise comes from rolling waves, and the only price tag is a couple of quid for chips on the harbour wall?
That’s where Wales truly shines.
Across its 870-mile coastline lie dozens of underrated seaside towns in Wales — places where time feels slower, nature feels closer, and adventures feel more personal. These are towns where budget-conscious travellers can get stunning views, delicious local food, and peaceful beach days without the premium price tag or overwhelming crowds.
In this guide, you’ll discover five of the best underrated seaside towns in Wales, chosen for their affordability, peaceful atmosphere, beautiful landscapes, and accessibility for travellers aged 20–40. Whether you’re planning a weekend escape, a low-cost staycation, or a scenic road trip, these hidden gems offer the perfect coastal getaway.
Let’s dive in.
1. New Quay – A Quiet Dolphin-Spotting Haven on the Ceredigion Coast
Image suggestion: wide shot of New Quay harbour at sunset
New Quay is the kind of place most travellers dream of stumbling upon — a tranquil harbour town dotted with pastel houses, calm sandy beaches, and some of the clearest waters in Wales. While larger Welsh resorts pull in thousands of visitors every year, New Quay remains beautifully slow-paced, making it one of the most underrated seaside towns in Wales.
The main draw? Dolphins — and lots of them. Cardigan Bay is famous for its semi-resident bottlenose dolphin population, and New Quay is one of the best (and cheapest) places to spot them. You can join a budget-friendly boat tour or simply watch from the harbour wall with an ice-cream in hand. cardigan-bay.com+1
The town’s beaches — including Harbour Beach, Dolau Beach, and the quieter Traeth Gwyn — are clean, calm, and perfect for paddling, swimming, or relaxing on warm days. Coastal paths wind their way along cliffs, offering incredible views of the bay and plenty of opportunities to escape into nature. ALONG DUSTY ROADS

2. Aberdyfi (Aberdovey) – Golden Sands, Quiet Charm & Snowdonia Views
Image suggestion: long beach in Aberdyfi at golden light
Set along the Dyfi Estuary on the southern edge of Snowdonia National Park, Aberdyfi feels like a secret coastal sanctuary. Its sweeping golden beach stretches for miles, backed by rolling dunes and calm estuary water that glows beautifully in afternoon light. Unlike busier North Wales towns, Aberdyfi retains a gentle village feel — peaceful streets, pastel cottages, and a harbour where life moves slowly.
Despite its tranquillity, Aberdyfi offers plenty to do. Explore its long beach, try paddleboarding on the estuary, grab chips on the seafront wall, or hike to panoramic viewpoints above the town. For outdoorsy travellers, the combination of coast and mountains gives this destination a unique appeal.
Foodies will also enjoy Aberdyfi’s local pubs, seafood spots, and bakeries — many of which serve fresh local ingredients at fair prices.
Why It’s a Hidden Gem
It’s one of the most scenic seaside towns in Wales yet remains relaxed and affordable. The long sandy beach feels wild and untouched, and the combination of coast plus mountains gives the town a dramatic beauty rarely found elsewhere.

3. Porthcawl – Retro Promenades, Secret Beaches & Fantastic Value
Image suggestion: Rest Bay beach in Porthcawl with surfers
While Porthcawl doesn’t always make the “prettiest seaside towns” lists, it absolutely wins when it comes to affordability, charm, and variety. Once a Victorian holiday hotspot, today Porthcawl balances retro seaside fun with peaceful natural spaces — especially if you wander beyond the central promenade.
Rest Bay is one of Wales’s best surfing beaches, with reliable waves, soft sands, and a friendly surfing scene. It’s extremely popular with beginner surfers, and board hire is affordable. For quieter moments, Newton Beach and Pink Bay offer calm, scenic spots where you can sit on the sand and watch the sun set over the water.
Evenings in Porthcawl have a nostalgic charm — colourful arcades, traditional chip shops, and coastal walks that feel cosy and comforting. It’s a place where simple pleasures still matter: ice cream on the seafront, wave-watching from the promenade, strolling along clifftops with a warm breeze in your hair.
Why It’s a Hidden Gem
It’s one of the best-value seaside towns in Wales, offering family-friendly beaches, surfing, coastal walks, and cheap food options. You can have a full beach day here without spending more than a tenner.

This town is ideal for travellers who want a peaceful seaside escape with a touch of Welsh history. Criccieth Castle stands proudly on its rocky headland, offering breathtaking views in all directions.

5. Penarth – A Quieter Alternative to Cardiff’s Bustling Bay
Image suggestion: Penarth Pier at sunset overlooking Bristol Channel
Just a short train ride from Cardiff, Penarth is one of the most underrated seaside towns in Wales, offering elegant Victorian charm, peaceful pebble beaches, and a beautifully restored pier overlooking the Bristol Channel.
Penarth is a dream for walkers. The clifftop boardwalk leads into Cardiff Bay, while the Wales Coast Path reveals dramatic cliff scenery and sweeping sea views. The town’s colourful Esplanade is lined with independent cafés and restaurants—many far cheaper than similar spots in Cardiff.
Penarth Pier Pavilion is the heart of the seafront, with its vintage look, art exhibitions, and calm atmosphere. At sunset, this is one of the most romantic seaside spots in South Wales.
