The Traveling Taylors

Wales is famous for its castles — over 600 of them, in fact — but most travelers stick to the same big names: Caernarfon, Conwy, Cardiff. While those are impressive, some of the most memorable experiences we’ve had came from wandering quiet ruins with no one else around. These lesser-known Wales castles offer wild beauty, gripping history, and fewer tourists. Here’s where to find them.

1. Castell y Bere – A Lonely Mountain Fortress

Tucked into the rugged slopes of southern Snowdonia, Castell y Bere was built by Llywelyn the Great in the 13th century to defend Welsh territory. Today, its mossy stones and dramatic views feel like stepping into a fantasy novel.

Reading about a place is great, but experiencing it in person is even better—and a compact selfie stick tripod like this one makes it easy to capture photos and videos without needing to ask strangers for help.

Why Visit: Remote and hauntingly beautiful — you’ll likely have it all to yourself.

2. Dolbadarn Castle – A Tower with a View

Overlooking Llyn Padarn near Llanberis, this compact round tower once guarded a key mountain pass. Though smaller than nearby giants like Caernarfon, Dolbadarn holds major historical weight as a symbol of native Welsh power. If you’d like it included on a wider itinerary, join the Snowdonia and three-castle day tour that stops at Dolbadarn.

Pro Tip: Combine it with a hike in Snowdonia or a visit to the National Slate Museum.

3. Dinefwr Castle – Ruins in a Deer Park

Located above the River Tywi in Carmarthenshire, Dinefwr is a romantic ruin surrounded by woodland and roaming deer. A climb to the top offers panoramic views of the valley — especially stunning in autumn.

Bonus: Entry is free, and it’s part of a larger estate with a historic house and walking trails. Because the weather can change quickly while navigating the castle on foot, some travelers keep their phone protected in a waterproof pouch like this one so they can still check maps even during rainy walks.

4. Carreg Cennen – The Cliffside Mystery

This castle is perched dramatically on a limestone crag, 300 feet above the River Cennen. It’s one of the most striking settings of any Welsh castle — and there’s even a dark cave beneath it that you can explore with a flashlight.

Quick Warning: The climb up is steep but short — wear good shoes.

5. Ewloe Castle – Hidden in the Woods

This small, ivy-covered ruin is tucked in a forest near Deeside, and it feels like nature has taken it back. Built by the Welsh princes of Gwynedd, it’s rarely busy and perfect for a quiet, atmospheric detour.

What We Loved: No ticket booth, no fanfare — just history and birdsong.

6. Llansteffan Castle – Overlooked Coastal Beauty

With sweeping views over Carmarthen Bay, Llansteffan Castle guards a gorgeous stretch of beach and estuary. It’s easily reached from the village below, yet often missed by visitors heading west. Thinking about visiting Wales soon? Keeping important items secure while traveling is easier with a hidden money belt like this one designed to store passports, cards, and cash.

Insider Tip: Time your visit for low tide and explore the beach after your castle climb. Many travelers pack a versatile one-piece swimsuit like this one for beach days or water activities.

7. Tretower Court & Castle – A Medieval Time Capsule

This one’s a two-for-one: a ruined Norman keep and a beautifully restored medieval manor house. Unlike most of the castles on this list, Tretower lets you step inside history — complete with furnished rooms and interpretive displays.

Great For: Families, history lovers, or anyone wanting a more immersive castle experience.
