North Wales Travel Guide: UK’s Best Castles + How to See Them Your Way

Destinations • Europe • UK • Weekend City Guides

June 9, 2026

It’s June, the peak travel season. We arrive at the colossal fortress, Caernarfon Castle. As we push through the wooden doors, thick enough to cease a battering ram, we step into an immense empty courtyard of this fortress. Almost no one else is there.

Meanwhile, at the Tower of London, thousands of people are stuffed like sardines into roped-off rooms, and funneled in a prescribed order. As for us? We scaled towers, ducked through stone passageways, and I did a handstand in the castle courtyard. Did it happen if no one saw it? Read on to find out.

This is the North Wales itinerary guide for people who are doing a UK trip (or are already in Europe and want to take a short weekend break) and want to know if Wales is worth the detour. (Spoiler alert: It is.)

So, how do you see multiple UNESCO World Heritage Sites like they’re still hidden from the world and you’re the only one with the map? You go to North Wales.

Why North Wales and How Long You Actually Need

A three-day London trip? Skip Wales. There isn’t enough time and the drive doesn’t earn its keep for a quick stop.

A 10-day or two-week UK trip that includes London and other stops like Bath, Stonehenge, or Edinburgh? North Wales belongs on that list. It’s roughly a 5-hour drive from London, or about a 3-hour detour when you’re already heading north toward Scotland. That sounds like a lot until you consider what you’re trading: a UNESCO-listed castle you can actually explore, mountain scenery that makes you pull over (and sheep who’ve decided the road is theirs), and a part of Britain that most UK visitors never see.

Wales has more castles per square mile than anywhere else in the world. Because it’s not on everyone’s radar, you can experience the real thing without the managed, roped-off, funneled through a maze of rooms and out a gift shop version of history that the most popular sites offer.

Already living in Europe, or there for an extended trip? North Wales belongs on your long weekend list.

Two full days is the sweet spot. One dedicated day, if that’s what your itinerary allows, still gets you the most important stops. A focused afternoon of Caernarfon, the long-name photo on Anglesey, and a walk around Conwy is genuinely worth it if you’re already in the region as part of a bigger trip.

Getting There: Flying In and Renting a Car

A car is essential for North Wales. Public transport exists, but everything in this guide is easier with your own wheels. Plan to hire one (or a driver) at the airport so you’re never dealing with city traffic.

Closest airports to North Wales

Liverpool John Lennon Airport is the closest major airport to North Wales. Once you’re off the plane and out of Liverpool, you’re in Wales within minutes. If you’re flying a budget carrier from mainland Europe and North Wales is your main destination, check flights to Liverpool first.

Manchester Airport is about 30 minutes further but has more routes and tends to have better fares. Either one puts you at the Welsh border in under an hour.

Flying into London from another continent?

Heathrow is your best option if you’re doing a broader UK trip that includes London. It sits on the western edge of the city, which means you can pick up your rental car and head west without crossing London at all. From Heathrow, you’re looking at a 4 to 5 hour drive to North Wales.

Gatwick sits south of London, which means you cross the city before heading west. It adds 30 to 60 minutes and more stress. If you have the choice, go with Heathrow.

Flying into London from Europe?

Flying a budget carrier from Europe into a secondary London airport? Luton is your best bet. It sits north and west of the city, which shaves meaningful time off the drive compared to Stansted, which is further east.

Coming from elsewhere in the UK?

From Scotland, drop south from the M6, cross into Wales, and you’re in the heart of North Wales within an hour. If you’re already heading from London to Scotland, North Wales isn’t a detour so much as a slight adjustment in direction. It’s right there on the map.

Caernarfon Castle: The Must-See on Every North Wales Itinerary

Wales has more castles per square mile than anywhere else in the world. They appear on hilltops, cliff edges, and harborfronts with a frequency that starts to feel almost normal, and then doesn’t. For a North Wales itinerary, one castle rises above everything else. It’s the main reason to come. Everything else gets layered in based on how much time you have.

Most heritage sites funnel you through pre-selected rooms, you see what they want you to see, in the sequence they’ve decided, and then you exit through the gift shop. Caernarfon doesn’t work that way.

Walk in and the castle is yours. You can climb the towers, walk the full circuit of the walls, and duck into narrow stone passageways that spiral upward with no guarantee of where they come out. My 2011 journal says “could do almost anything @ Caernarfon Castle,” and after multiple visits that’s still the most accurate description of the experience.

What you’re actually looking at

Edward I built Caernarfon in the 13th century as the centerpiece of his Welsh fortresses, and it’s still in remarkable condition for something that old. It’s part of a UNESCO-listed quartet along with Conwy, Beaumaris, and Harlech, considered some of the finest examples of medieval military architecture in Europe. Standing on top of the Eagle Tower looking out over the Menai Strait toward Anglesey with Snowdonia behind you, the structure underneath your feet is largely the original 13th-century stone.

The castle is also where the Investiture of the Prince of Wales takes place. Charles was formally invested here on 1 July 1969, watched by millions on television. The tradition goes back to Edward I, who started the custom of investing his heir as Prince of Wales at Caernarfon. Standing in that same courtyard, with almost no one else around, you feel the accumulated weight of 700 years of deliberate symbolism in a way that a crowded, roped-off site simply can’t deliver.

Go early. This cannot be said enough.

We arrived at opening time on a Monday morning in June and spent two full hours inside with perhaps a dozen other people in a castle that could hold several thousand. The castle never reaches Tower of London crowding levels, but the difference between arriving at 9:30 and arriving at 11 AM is significant. Get there at opening and the place is yours. Tour buses arrive mid-morning. By the time they do, you’ve already done a handstand in the courtyard and seen everything worth seeing.

Conwy: Castle, Walls, and the Smallest House in Britain

Conwy is the second of the UNESCO quartet and worth its own visit. The medieval town walls are some of the most complete in Europe, Conwy Castle dominates the skyline from every angle, and the town has a quieter character than Caernarfon that rewards wandering.

On the 2024 trip with the kids, time was limited. We made a beeline for the quayside, did a quick walk on part of the city walls, and that was enough to make the stop worthwhile. The quayside is where you’ll find the Smallest House in Great Britain, tucked against a row of larger buildings, which makes you do a double take.

The measurements: 72 inches wide, 122 inches high. The last occupant: a fisherman who was 6 foot 3 and lived there until 1900, presumably spending most of his time folded in half. The Guinness Book of Records confirmed its status in the early 1920s, and it still belongs to the same family. A woman in traditional Welsh dress stands in the doorway and collects a small entrance fee if you want to go inside. It’s £1.50 and takes about three minutes, which is perfect.

Eat seafood in Conwy

Conwy is famous for its mussels. The town has been harvesting them from the estuary since medieval times, and the quayside restaurants reflect that. If you’re stopping in Conwy anyway, eating something pulled from the water nearby is the right call. Fresh Conwy mussels with crusty bread are the thing to order.

More North Wales Castles Worth Adding to Your Trip

The full UNESCO quartet is Caernarfon, Conwy, Beaumaris, and Harlech. We’ve driven past the outsides of Beaumaris and Harlech on multiple trips. Neither has gotten the proper visit it deserves yet, which tells you something about how much there is to see.

Harlech Castle is perched on a cliff above Cardigan Bay, with views that are reportedly even more dramatic than Caernarfon’s. It inspired the Welsh song “Men of Harlech,” and it looks exactly like a castle that would inspire a song. If you’re building a longer North Wales itinerary, Harlech is the next castle to add after Caernarfon and Conwy.

Further along Anglesey, Beaumaris Castle is considered the most technically perfect concentric castle design in Britain. It was never actually finished, which architectural historians find very interesting and which is worth knowing when you’re standing in front of it wondering what’s missing.

For something smaller and genuinely off the main tourist circuit, Gwrych Castle sits right on the north coast. In North Wales, “less visited” is its own recommendation.

Wanna Feel Like Royalty? Sleep in a Castle

Staying in a castle is on a lot of people’s lists. Most people don’t realize how easy it is to actually do.

Bodelwyddan Castle is visible from the A55 as you enter North Wales, the white-stone Gothic Revival facade the kind of building that makes you yell “OH what’s that!” and immediately Google Map it. On our 2011 trip we toured it when it was open as a historic home, it had an interior fit for royalty.

Today Bodelwyddan operates as a hotel, which means you can actually sleep there. Worth knowing before you book: the dramatic exterior is largely a 19th-century Gothic Revival remodel of a much older house, not an actual medieval fortress.

We’ve done castle hotel stays elsewhere on our travels and the experience of waking up inside walls that old, with views of a countryside you only see in movies, and discovering what it must have felt like to be rich several centuries ago, is worth doing at least once. If a castle stay is on your list and you’re building a North Wales itinerary, Bodelwyddan is right at the entrance to the region. Check current availability and rates at Warner Hotels here.

Beyond the Castles: Snowdonia, Long Names, Seafood, and Slate

Castles dominate any list of things to do in North Wales, but the walking down corridors that look exactly like what your imagination produces when someone says “castle,” is worth doing at least once. If a castle stay is on your list and you’re building a North Wales itinerary, Bodelwyddan is right at the entrance to the region. Check current availability and rates at Warner Hotels here.

The Town With the Longest Name in Europe

Crossing from mainland Wales onto Anglesey, you’ll pass through a town with a name that takes approximately 45 seconds to say out loud. We’ve done this route multiple times and the sign never gets old.

Stop at the train station. The famous red sign spans the full length of the building where everyone takes the photo. The station also has a gift shop, a cafe, and clean bathrooms — another practical reason to stop.

Which translates to: “St Mary’s Church in the Hollow of the White Hazel near the Rapid Whirlpool and the Church of St Tysilio near the Red Cave.”

Snowdonia National Park and Snowdon Summit

Snowdonia National Park is visible from the road on the drive toward Caernarfon, and the landscape shifts completely once you leave the A55 heading south. You will pull over. There is no avoiding it. The park covers 827 square miles of mountains, lakes, and forests.

Snowdon itself is the highest peak in Wales at 3,560 feet. You can hike it via several routes, the most popular being the Llanberis Path, or take the Snowdon Mountain Railway from Llanberis all the way to the summit. We have driven past the base of Snowdon on multiple trips. The railway in particular keeps getting bumped to the next visit. On a longer North Wales itinerary, this is the first thing to add. Book the railway well in advance, especially in summer.

Pontcysyllte Aqueduct

The Pontcysyllte Aqueduct, near Wrexham, is the highest canal aqueduct in the world. At 127 feet it carries the Llangollen Canal over the River Dee, designed by Thomas Telford and completed in 1805. UNESCO listed it in 2009. You can walk across the towpath, which sounds peaceful until you’re 127 feet above a river with no railing on one side.

We drove past without stopping on our first trip because we needed to get home. Even from the road, the scale is striking. The walk across is firmly on the return list.

Roman History: Segontium Fort

Caernarfon’s military history predates Edward I by roughly a thousand years, which is easy to forget when you’re standing inside a 13th-century fortress. Segontium Roman Fort, just outside the town center, was garrisoned from around 77 AD through the late 4th century. Entry is free.

The Copper Mines

Not everything in North Wales is medieval. The region also has significant prehistoric and industrial history, and the copper mines are the best way to access it. Sygun Copper Mine near Beddgelert is self-guided. Great Orme Mines above Llandudno are among the largest prehistoric copper mines ever discovered anywhere in the world. Both are good for families who need a break from castle-climbing, and either one adds a legitimate half-day to a longer itinerary.

Buy Slate Before You Leave

North Wales is slate country. The quarries around Snowdonia once supplied rooftops across the British Empire, and the material is still everywhere. Before you head home, look for Welsh slate gifts: cheese boards, coasters, placemats, and small serving pieces made from stone that’s genuinely 500 million years old. They’re well made, priced fairly, and not something you’ll find anywhere else.

One practical note: get it wrapped properly before you travel. Slate is heavy, the edges are sharp, and it can fracture easily. It does not survive a checked bag packed carelessly. Ask the shop to wrap it, or pick up bubble wrap from a hardware store. The cheese board will make it home. It just needs a little help.

Elevate Your Trip: Fancy Eats and Good Sleeps Near Snowdonia

Two days in North Wales means you can stay near Snowdonia rather than driving home on the same day. The Snowdon massif is visible from the road. The landscape shifts dramatically once you leave the coast road.

If food matters to you on a trip, North Wales rewards it. There are two places to stay near Snowdonia worth knowing about: Tyddyn Llan in Llandrillo and Palé Hall near Bala. Palé Hall holds a Michelin Key, and both have Michelin-recommended restaurants. Either one turns your trip to Snowdonia into a luxury stay.

We stayed at Tyddyn Llan in 2011. For dinner, we had the multi-course tasting menu and were deliriously full by the third course. When the half grouse arrived later in the meal, we took one bite each just to say we’d tried it. After a day of climbing around medieval fortresses, this was the right kind of problem.

The breakfast the next morning received a one-word entry in my journal, capitalized for emphasis: AWESOME. (It earned it.)
