58 Best Sights in Wales

About 5 miles southwest of Brecon you encounter mountains and wild, windswept uplands that are tipped by shafts of golden light when the weather's fine, or fingers of ghostly mist when it's not. This 519-square-mile park is one of Wales's most breathtaking areas, perfect for a hike or scenic drive; it's also one of the world's few accredited International Dark Sky Reserves, which means it's an excellent location for star-gazing. Start at the visitor center on Mynydd Illtyd, a grassy stretch of upland west of the A470 at Libanus. Also known as the Mountain Centre, it's an excellent source of information about the park, including maps and advice on the best routes (guided or self-guided). There's also an excellent tearoom where you can fuel up for the journey or reward yourself with an indulgent slice of cake afterward. If you want to see it all from your car, any road that crosses the Beacons will offer you beautiful views, but the most spectacular is the high and undulating A4069, between Brynamman and Llangadog in the park's western end.

To explore the moorlands on foot, come prepared. Mist and rain descend quickly, and the summits are exposed to high winds.

The town of Beaumaris dates from 1295, when Edward I commenced work on this impressive castle, the last and largest link in an "iron ring" of fortifications around North Wales built to contain the Welsh. Guarding the western approach to the Menai Strait, the unfinished castle (a World Heritage Site) is solid and symmetrical, with concentric lines of fortification, arrow slits, and a moat: a superb example of medieval defensive planning.

Undoubtedly one of the best gardens in Wales, Bodnant Garden is something of a pilgrimage spot for horticulturists from around the world. Laid out in 1875, the 87 acres are particularly famed for rhododendrons, camellias, and magnolias. Visit in late May to see the laburnum arch that forms a huge tunnel of golden blooms. The mountains of Eryri (Snowdonia) form a magnificent backdrop to the Italianate terraces, rock and rose gardens, and pinetum. The gardens are about 5 miles south of Conwy.

The grim, majestic mass of Caernarfon Castle, a UNESCO World Heritage Site, looms over the waters of the River Seiont. Numerous bloody encounters were witnessed by these sullen walls, erected by Edward I in 1283 as a symbol of his determination to subdue the Welsh. The castle's towers, unlike those of Edward I's other castles, are polygonal and patterned with bands of different-color stone. In 1284 the monarch thought of a scheme to steal the Welsh throne. Knowing that the Welsh chieftains would accept no foreign prince, Edward promised to designate a ruler who could speak no word of English. Edward presented his infant son to the assembled chieftains as their prince "who spoke no English, had been born on Welsh soil, and whose first words would be spoken in Welsh." The ruse worked, and on that day was created the first prince of Wales of English lineage. In the Queen's Tower, a museum charts the history of the local regiment, the Royal Welch Fusiliers. In 1969, the castle was the location of the investiture of King Charles III as Prince of Wales, an event featured in the third season of the hit Netflix series The Crown. The castle is undergoing a £4 million renovation to turn the King's Gate main entrance into an accessible visitor center. The castle is in the town of Caernarfon, 7 miles west of Llanberis.

The largest and most impressive fortress in Wales, and one of the few still to be surrounded by its original moat, Caerphilly must have been awe-inspiring at the time of its construction in the 13th century. Built by an Anglo-Norman lord, the concentric fortification contained powerful inner and outer defenses. It was badly damaged during the English Civil War (check out the leaning tower), although extensive renovations have restored much of its former glory. The original Great Hall is still intact, although a £10-million restoration project on it is currently ongoing. Once inside the main entrance, on the far left, there's a replica of a trebuchet—a giant catapult used to launch rocks and other projectiles at the enemy. Additionally, an interesting collection of modern interpretive sculptures has been placed around the castle, both inside and outside. To celebrate the town's famous cheese, a free festival, the Big Cheese, is usually held here every year at the end of July; however, it will take place in the town center until the castle's restoration is finished. Caerphilly is 7 miles north of Cardiff.

A wealth of legend, poetry, and song is conjured up by the 13th-century Harlech Castle, built by Edward I to help subdue the Welsh. Its mighty ruins, visible for miles, are as dramatic as its history (though you have to imagine the sea, which used to crash against the rocks below but receded in the 19th century). Harlech was occupied by the Welsh Prince Owain Glyndwr from 1404 to 1408 during his revolt against the English. The music of the traditional folk song "Men of Harlech" refers to the heroic defense of this castle in 1468 by Dafydd ap Eynion, who, summoned to surrender, is alleged to have replied: "I held a castle in France until every old woman in Wales heard of it, and I will hold a castle in Wales until every old woman in France hears of it." On a clear day you can climb the battlements for a spectacular view of the surrounding countryside. A helpful visitor center explains the castle's history; you can also arrange to stay overnight in one of five luxury apartments overlooking the castle. The castle dominates the coastal town of Harlech, 12 miles south of Porthmadog.

This impressive medieval fortress has evolved from its 14th-century origins into a grand home complete with an 18th-century servants' hall and interiors furnished in 16th- to 19th-century styles. However, it still looks satisfyingly medieval from the outside—and belowground, where you tour the original dungeons. Surrounding the castle are beautiful formal gardens and parkland. Chirk Castle is 5 miles southeast of Llangollen.

Dylan Thomas was born in this suburban Edwardian house, which remains a place of pilgrimage for the poet's devotees. You can wander the house with no restrictions (they're proud of the fact that nothing is roped off), or prebook tours that are tailored according to how much time you want to spend here. You can also arrange tours of other Thomas-related sites in Swansea and farther afield in the region. The whole house can be rented as self-catering accommodation for around £300 for a minimum two-night stay. You can also book afternoon tea and an Edwardian-theme dinner.

Stretching from the Welsh midlands almost to its northern coast, Eryri (Snowdonia) National Park covers a vast swath of North Wales. The park consists of 823 square miles of rocky mountains, valleys clothed in oak woods, moorlands, lakes, and rivers, all guaranteeing natural beauty and, to a varying extent, solitude. Its most famous attraction, by far, is the towering peak of Mt. Snowdon ("Yr Wyddfa" in Welsh), the highest mountain in Wales. The view from the top is jaw-dropping: to the northwest you can see the Menai Strait and Anglesey; to the south, Harlech Castle and the Cadair Idris mountain range. To the southwest, on an exceedingly clear day, you can make out the distant peaks of Ireland's Wicklow Mountains. There are six different walking paths to the top, but a far less punishing way is via the Snowdon Mountain Railway in nearby Llanberis.

Perched at the top of Yr Wyddfa (Snowdon) is Hafod Eryri, an eco-friendly replacement for the previous visitor center (once described by King Charles III as "the highest slum in Wales"). The granite-roof building, which blends beautifully into the rocky landscape, has a café and exhibitions about the mountain, its ecology, and its history. If you're planning to make the ascent, the visitor center in Betws-y-Coed is the best place to stop for information.

Founded in the early 19th century to carry slate, the Ffestiniog Railway starts at the quayside and climbs up 700 feet through a wooded vale, past a waterfall, and across the mountains. The northern terminus is in Blaenau Ffestiniog, famous for its slate mines, where you have a 40-minute break to look around. The Ffestiniog Railway is perhaps the best of several small steam lines in this part of the country. Porthmadog gets very crowded in summer, and parking is limited, so you might want to make this journey from Blaenau Ffestiniog to Porthmadog instead. Check the website for the daily timetables for "Mountain Spirit" and "The Quarryman."

This peninsula, which stretches westward from Swansea, was the first part of Britain to be designated an Area of Outstanding Natural Beauty. Its shores are a succession of sheltered sandy bays and awesome headlands. The seaside resort of Mumbles, on the outskirts of Swansea, is the most famous town along the route. It's a pleasant place to wander on a sunny afternoon, with a Norman castle, an amusement pier, and a seaside promenade, as well as a variety of independent cafés and boutiques. Farther along the peninsula, the secluded Pwlldu Bay can only be reached on foot from nearby villages like Southgate. A few miles westward is the more accessible (and very popular) Three Cliffs Bay, with its sweeping views and wide, sandy beach. At the far western tip of the peninsula, Rhossili has perhaps the best beach of all. Its unusual, snaking causeway—known locally as the Worm's Head—is inaccessible at high tide. Gower is a popular destination with surfers and you'll find many other water sports offered here.

Bordered by lush forest and emerald green hills, Lake Vyrnwy is a haven for wildlife. It's rich in rare bird species, from falcons to siskins and curlews. Stretching out along the shores of the lake near the visitor welcome point, the Lake Vyrnwy Sculpture Park is a collection of pieces by talented local artist Andy Hancock. Arranged along a paved walking trail, many of the wooden sculptures resemble oversize versions of the lake's wildlife, including a 15-foot-long dragonfly. It's an extremely popular cycling route, and there's a bike shop and coffee shop near the visitor welcome point.

This 568-acre, 18th-century estate is dotted with lakes, fountains, and a Japanese garden. The centerpiece is the Norman Foster–designed Great Glass House, the largest single-span greenhouse in the world, which blends into the curving landforms of the Tywi Valley. The greenhouse's interior landscape includes a 40-foot-deep ravine and thousands of plants from all over the world. The Ghost Forest is a stunning art installation, made from the carved stumps of 10 giant hardwood trees—a powerful statement on how rapidly the world's forests are being destroyed. Also here is the British Bird of Prey Centre, where you can watch native raptors flying daily, including a golden eagle. The grounds have lovely views across the Carmarthenshire countryside, especially from the Paxton's View lookout point. It's marked by Paxton's Tower, a Gothic folly built to honor Horatio Nelson, now owned by the National Trust (it's free to wander, though there's nothing to see inside). The garden, 20 miles northwest of Swansea, is signposted off the main road between Swansea and Carmarthen.

By far the smallest of the country's three national parks, Pembrokeshire Coast is no less strikingly beautiful than the other two. The park has several Blue Flag beaches and a host of spectacular cliff-top drives and walks, including some of the most popular stretches of the Wales Coast Path. The park has a smattering of historic sites, including the impossibly picturesque St. Davids Cathedral, built in a Viking-proof nook by the Irish Sea. The information center in St. Davids is a good place to start.

From 1778 to 1828 Plas Newydd (not to be confused with the similarly named Isle of Anglesey estate) was the home of Lady Eleanor Butler and Sarah Ponsonby, the eccentric Ladies of Llangollen, who set up a then-scandalous single-sex household, collected curios and magnificent carvings, and made it into a tourist attraction even during their lifetimes. You can take tea there, as did Wordsworth and the Duke of Wellington, and stroll in the attractively terraced gardens.

Some historians consider Plas Newydd to be the finest mansion in Wales. Remodeled in the 18th century by James Wyatt (1747–1813) for the marquesses of Anglesey (whose descendants still live here), it stands on the Menai Strait about 7 miles southwest of Beaumaris. The interior has some fine 18th-century Gothic Revival decorations. Between 1936 and 1940 the society artist Rex Whistler (1905–44) painted the mural in the dining room. A museum commemorates the Battle of Waterloo, where the first marquess led the cavalry. The woodland walk and rhododendron gardens are worth exploring. Plas Newydd is not to be confused with the Gothic mansion of the same name in Llangollen.

From the Llangollen Canal Wharf you can take a 45-minute trip on a narrow boat (a slender barge) along the canal to the world's longest and highest navigable cast-iron aqueduct: Pontcysyllte (Welsh for "the bridge that connects"), a UNESCO World Heritage Site. The aqueduct is more than 1,000 feet long. Pontcysyllte is 3 miles east of Llangollen.

Continuously occupied since the 13th century, Powis Castle rises above the town of Welshpool. One of the most elegant residential castles in Britain, Powis is equally renowned for its magnificent terraced gardens. The interior contains an outstanding art collection, from Greek vases to paintings by Thomas Gainsborough and Joshua Reynolds. The Clive of India Museum contains perhaps the most extensive private collection of antique Indian art in Britain. Powis Castle is north of Llandrindod Wells on the A483.

The last abbey of the Cistercian order to be founded in Wales, Valle Crucis was built in 1201 and abandoned in 1537—a victim of Henry VIII's violent dissolution of the monasteries. Today it's a highly picturesque ruin beside a glassy lake. Surprisingly large sections survive relatively intact—particularly the sacristy and more or less complete chapter house, with its intricate vaulted ceiling. In its day Valle Crucis was one of the richest and most powerful abbeys in Wales; despite half a millennium of decay, this is still an impressive site to wander. It's currently only open for guided visits.

The British writer Caitlin Moran once wrote fondly of Aberystwyth's "Glitter-glue sea and smashed-cake castle," and these crumbling ruins at the southern end of the bay do have an endearing quality. Built in 1277, the castle was one of the key strongholds captured in the early 15th century by Owain Glyndwr, a Welsh prince who led the country's last serious bid for independence from England. Today it's a romantic, windswept ruin, rather incongruously used as a cut-through walking path by locals for whom it's nothing out of the ordinary at all. To find the ruins, just walk along the bay, away from the town center; they are located just after the pier.

The Victorian-era Aberystwyth Cliff Railway deposits you at the top of Constitution Hill. At the top is a camera obscura, a course to play crazy golf, and a café. Opened in 1896, it's the longest electric cliff railway in Britain.

The steam-powered train runs along the southern shores of Bala Lake (Llyn Tegid, or "Lake of Beauty"), a large natural reservoir just northeast of Lake Vyrnwy. Bala Lake is also popular for kayaking and other water sports. Look on the website for departure times.

A UNESCO World Heritage Site, the 1789 Blaenafon Ironworks traces the entire process of iron production in the late 18th century. Well-preserved blast furnaces, a water-balance lift used to transport materials to higher ground, and a terraced row of workers' cottages show how the business operated. The entrance to the site is on Estate Road.

Dating from around 3000 BC, this megalithic passage tomb is the most complete site of its kind in Wales. You enter via a narrow opening built into a burial mound. The passage extends for around 25 feet before opening out into a wider burial chamber. The far wall, made of quartz, is illuminated at dawn on the summer solstice. Bring a flashlight, as the tomb has no artificial lighting. Next to the entrance is a replica of a stone pillar carved with Celtic spirals, found here in 1928. The original is in the National Museum in Cardiff. The site is 7 miles southwest of Beaumaris.

One of the great drives of North Wales, the sweeping, vertiginous panoramas of Bwlch y Groes (Pass of the Cross) form the second-highest mountain pass in the country at 1,788 feet. From Lake Vyrnwy, drive for a mile on B4393 before heading west on the mountain road.

This beautiful little island off the coast at Tenby has whitewashed stone buildings that lend it a Mediterranean feel. The island is best known for its Cistercian order, whose black-and-white-robed monks make a famous perfume from the local plants. You can visit tiny St. Illtyd's Church to see the Caldey Stone, an early Christian artifact from circa AD 600, engraved in Latin and ancient Celtic. St. David's Church, on a hill above the village, is a simple Norman chapel noted for its art-deco stained glass. The monastery itself isn't open to the public, but its church has a public viewing gallery if you want to observe a service. Boats to Caldey Island leave from Tenby's harbor every 20 minutes or so between Easter and October.

Perhaps the most potent symbol of Cardiff's 21st-century rebirth, this regenerated district is a 10-minute bus ride on the Baycar from Canal Street. It's the location of Senedd Cymru, the Welsh Parliament, and Wales Millennium Centre, as well as a good selection of restaurants and bars. Don't miss the Norwegian Church Arts Centre, where children's author Roald Dahl was baptized; you can also take a boat trip around the bay. It was from Roath Dock in 1910 that Captain Robert Falcon Scott and his crew left aboard the SS Terra Nova for their ill-fated British Antarctic Expedition.

In the Victorian seaside resort of Criccieth, a few miles west of Porthmadog on the A497, a medieval castle with sweeping views crowns the headland. Criccieth was the scene of the last real uprising against English rule in Wales, in the early 1400s, when it was attacked and burned by rebel prince and latter-day folk hero Owain Glyndwr (1359–1416). David Lloyd George, who was prime minister of Britain for most of World War I, grew up in Wales and lived in the town; a small museum in his childhood home honors him.

This romantic hilltop ruin looks out over a breathtaking patchwork of green fields and mountains. The fortress was built in the 1260s on the site of an earlier castle, which was an Iron Age fort before that. Its heyday was incredibly short lived; by the end of the 13th century it had been captured and abandoned by English forces after which it gradually fell into ruin. The castle is located on top of a hill just north of Llangollen town center. There are no roads to the summit; the best walking path starts at Canal Bridge in Llangollen and zigzags up the side of the hill. The rather punishing hike is a little over a mile long.

At the northern end of the beach promenade, Constitution Hill dominates the skyline. From the top you can see much of the Welsh coastline (and, on exceptionally clear days, Ireland). There's a small café at the top and plenty of space for a picnic. If you're feeling hale and hearty, there's a long footpath that zigzags up to the 430-foot summit. From there, a 5-mile-long coastal path stretches to the village of Borth, a smaller, sleepier resort north of Aberystwyth where the remains of a 3,000-year-old petrified forest may be seen on the beach at low tide.
