The Llŷn Peninsula: Wales' Best-Kept Secret
The Llŷn Peninsula is one of those places that flies under the radar—most people wouldn’t even know where to point to it on a map. Tucked away in North Wales, it’s often overshadowed by its flashy neighbours, Snowdonia and Anglesey. But that’s part of its charm. This Area of Outstanding Natural Beauty is a quiet, unspoiled corner of Wales, packed with stunning beaches, quirky pubs, and rugged coastal views.

If you’re after a proper escape without the crowds, the Llyn Peninsula is your spot. Here are five must-see places that’ll make you fall in love with this underrated slice of Wales.
1. Nefyn Beach: Clear Waters & Striking Views
Where to find it: LL53 6HL | ///TIES.INCISIONS.SAME
Nefyn Beach is the kind of place that makes you stop and just stare for a while. Tucked into the north coast of the Llŷn Peninsula, this long, sandy bay is sheltered by the Nefyn Headland, giving it that postcard-perfect look. The water here is ridiculously clear—more like something you’d find in the Mediterranean than North Wales.
Getting down to the beach can be a bit of a workout (some paths are steep), but it’s worth it. The northern side is dog-friendly, so if you’ve got a four-legged explorer with you, they’ll love it too. It’s quiet, it’s beautiful, and it’s the kind of spot where you can easily lose track of time.
2. Ty Coch Inn: A Pub on the Beach
Where to find it: Porthdinllaen, Morfa Nefyn, LL53 6DB | ///MASSIVE.DANCE.BRINK
Ever had a pint with your toes in the sand? The Ty Coch Inn is one of those places that feels like it shouldn’t exist—a proper, old-school pub plonked right on the beach. It’s been voted one of the top 10 beach bars in the world, and once you’ve been, you’ll see why.
Here’s the catch: you can’t drive to it easily. You can park at the Lon Golff car park (or the golf club) and walk about 20 minutes across the golf course or along Beach Road (just check the tides—high tide can cut off access). The walk is part of the fun, though. By the time you’re sipping a cold drink with the sea right there, you’ll be plotting your next visit.
3. Whistling Sands Beach: Golden Slopes & Quiet Vibes
Where to find it: Aberdaron, Pwllheli, LL53 8LH | ///EVOKED.VALIDATED.MEMORY
Officially called Traeth Porthor, this beach gets its nickname from the weird (and cool) phenomenon of the sand “whistling” underfoot when it’s dry. But that’s not even the best part. The sand here is golden, the water slopes in gently, and the whole place has a wild, untouched feel—like something you’d find in the Scottish Highlands, Llŷn Peninsulastyle.
There’s a National Trust car park, but the walk down to the beach is steep, so pack light or be prepared for a workout. Note that this beach can get busier in summer months so bear that in mind. Also, dogs aren’t allowed from April to September, but the coastal path nearby offers plenty of space for walks with a view.
4. Hells Mouth Beach: Wild & Dramatic
Where to find it: Llanengan, Abersoch, LL53 TLG | ///EXIT.PHEASANTS.FADE
With a name like Hells Mouth (Porth Neigwl in Welsh), you know this place isn’t messing around. This 3-mile stretch of beach is all about drama—big waves, wide-open space, and a proper “middle of nowhere” vibe. It’s a surfer’s dream, but even if you’re not into riding waves, it’s worth visiting just for the sheer scale of it.
There are no facilities here, so bring snacks, water, and maybe a picnic. The walk from the car park takes you through dunes, and once you’re there, you’ll feel like you have it mostly to yourself, there is so much space to spread out on this beach. Dogs are welcome year-round, making it a great spot for a long, peaceful walk.
5. Criccieth Castle & Beach: History with a View
Castle: Castle St, Criccieth, LL52 ODP | ///MODERATED.OFFERS.AWAITED
Beach: Criccieth, Gwynedd, LL52 OPS | ///CORKSCREW.CONSPIRE.SIDEBURNS
A must see in Llŷn Peninsula! Criccieth Castle is the kind of ruin that makes you wish walls could talk. Perched on a hill overlooking Tremadog Bay, this 13th-century fortress has seen its fair share of history. Tickets required – (£6.50 for adults, £4.60 for kids), but the coastline views from the top are next level. If you’d rather skip the ticket, head to Criccieth Beach instead—you’ll get an equally epic view of the castle from the sand.
Speaking of Criccieth Beach, it’s a mix of sand and shingle, with a promenade that’s perfect for a lazy stroll. The eastern section is dog-friendly (restrictions apply April–September), and the town itself has plenty of cafes and pubs for a post-beach refuel.
Top tip: If you want an epic photo of Criccieth Castle head to the beach at sunrise or sunset and stand on the section behind Cadwalders ice cream shop (you won’t regret it!).
