107 Best Sights in Wales

This late 18th-century Welsh gentry estate in the Aeron Valley, 17 miles south of Aberystwyth, is a superb example of the early work of John Nash (1752–1835). Nash was the leading architect of the Regency period and the designer of London's Marble Arch and Buckingham Palace. The estate survived with few changes until recently; it is a self-contained world with a farmyard, a bookshop, and a café. The walled gardens are particularly beautiful.

This restored standard-gauge steam line runs for 10 miles along the scenic Dee Valley. The terminus is near the town's bridge.

At these caverns you can descend 500 feet on Britain's deepest underground railway to a mine where you walk by an eerie underground lake. Here Victorian working conditions have been re-created, and the tour gives a good idea of the difficult lives the miners had to endure. Part of the mine is now used as a space to mature cheese. Wear sturdy footwear when visiting the mine—during busy times you may have to climb 70 steps as part of the tour.

Housed in a restored Edwardian building, this is the leading contemporary art gallery in Wales. Six spaces host temporary exhibitions along with a shop and café.

This well-executed museum tells the story of Cardiff and its people from the city's medieval origins to the present day. There's a particularly interesting exhibit on the old docks (now Cardiff Bay), one of the biggest ports in the world in the early 1900s. It's also worth a visit to see the building itself, formerly the Cardiff Free Library, which was built in the 1880s and is now a recognized historic building; note the lovely green ceramic tiles.

This distinctive 16th-century building in the town square has seven Dutch-style dormer windows, known as the "eyes of Ruthin," set into its red-tile roof. Formerly a pub, the building is not currently in use.

This is a worthwhile stop—for awesome views of Caernarfon Bay as well as cultural information—if you're exploring the Llŷn Peninsula. A former village for granite-quarry workers serves as the Welsh Language and Heritage Centre, offering Welsh-language classes and cultural courses (in Welsh). There's a tourist information center, a café that serves good sandwiches, and a modest exhibit of historical items, including an old quarryman's cottage fitted out exactly as it would have been in 1910. Some of the other cottages have been turned into B&Bs and self-catering accommodations.

Dating from 1435, the oldest known timbered house in Wales offers visitors the opportunity to see how its inhabitants lived throughout the centuries; there's a useful interactive display, too. A colony of Lesser Horseshoe bats lives in the attic and you can watch them via a bat cam. Outside, the original medieval garden has been restored.

Just a few miles south of Merthyr Mawr is this stunning promontory overlooking the Bristol Channel. Twin lighthouses stand guard against the elements; one, dating from 1832, is still operational, but the other is no longer in use. This is also a popular picnic spot, and a small snack kiosk is open during summer months. Nothing beats this place at sunset, when the evening sky ignites in a riot of color. It's one of the most romantic spots in South Wales. There's no guardrail on the cliff, so keep a close eye on children.

This quirky museum, housed in an art deco building, has a collection of more than 260 bicycles dating from 1818 to the present day.

This massive neoclassical building next to the University of Wales houses notable Welsh and other Celtic literary works among its more than 4.5 million volumes. The cache of public records makes it an invaluable tool if you're tracing your family tree. Also here is the National Screen and Sound Archive of Wales, which hosts lunchtime and evening film screenings.

Located within the remains of one of only three permanent Roman fortresses in Britain (built AD 75), this fascinating museum looks at all aspects of Roman life, and includes an exquisite collection of gemstones and a coffin complete with male remains. Of particular note are the ruins of the amphitheater, the baths, and the only Roman barracks on view in Europe. The reconstructed Roman garden is particularly attractive. Caerleon is 4 miles northeast of Newport.

This underground cave system was discovered by two local men in 1912—make that rediscovered, as one of the caves contained 42 human skeletons that had lain undisturbed for around 7,000 years. The main cave system, Dan Yr Ogof (Welsh for "beneath the cave"), is an impressive natural wonder, particularly the Cathedral Cave with natural stone archways and a dramatic waterfall. The whole thing is pitched at kids, with "dramatic" piped music to "enhance" the atmosphere, and a park featuring 200 life-size models of dinosaurs and other prehistoric creatures. There's also a playground, shire horse center, and a Victorian farm where kids can pet the animals. The caves are 17 miles southwest of Brecon.

In Padarn Country Park, this museum in the old Dinorwig Slate Quarry is dedicated to what was once an important industry for the area. The museum has quarry workshops and slate-splitting demonstrations, as well as restored worker housing, all of which convey the development of the industry and the challenges faced by those who worked in it. The narrow-gauge Llanberis Lake Railway departs from here.

Housed in a construction of steel, slate, and glass grafted onto a historic redbrick building, the National Waterfront Museum's galleries have 15 theme areas, presenting Welsh maritime and industrial history through state-of-the-art interactive technology and a host of artifacts. Highlights of the collection include a monoplane built by amateur aviation enthusiasts in the early 1900s, one of the oldest British aircraft in existence, as well as one of the last carriages from the Mumbles Train, the world's first passenger rail service (1807–1960). You'll also learn about Swansea's important international role in copper smelting in the 19th century.

Built in the 12th century, this abbey was, in its day, one of the largest and most important in the British Isles. Though just a shell, the main church gives an impressive sense of scale, with its tall buttresses and soaring, glassless windows. Here and there small sections of the original building have survived unscathed, including an undercroft with a vaulted stone ceiling. Neath Abbey is 9 miles northeast of Swansea.

Just south of the village are these atmospheric ruins, nestled by a river that can only be crossed via stepping-stones. A number of legends are associated with the castle, one concerning a ghost that supposedly forces passersby to embrace a large rock known as the "Goblin Stone." When you try to draw back, so the story goes, you find that your hands and feet have become part of the rock.

About 10 miles east of Tenby is this remarkably complete Norman fortress dating from 1199, where Henry VII was born in 1457. Its walls remain stout, its gatehouse mighty, and the enormous cylindrical keep proved so impregnable to cannon fire in the Civil War that Cromwell's men had to starve out its Royalist defenders. Climb the towers and walk the walls for fine views. Tours (included in the admission price) are offered at 11 am, noon, 1 pm, 2 pm, and 3 pm. A well-stocked gift shop sells faux-medieval knickknacks while the on-site café serves homemade snacks.

Topped by a distinctive redbrick clock tower, the Victorian Gothic Pierhead contains a good exhibition on the history of Cardiff Bay, then known as Tiger Bay, and the former docks. They have an occasional but eclectic program of public events here, including art exhibitions, talks, and debates; call or check the website for the upcoming schedule.

The peat-brown water of Pistyll Rhaeadr, the highest waterfall in Wales, thunders down a 240-foot double cascade. When you're driving on the B4500 between Llangollen and Llanwddyn, take the road leading northwest from the town of Llanrhaeadr ym Mochnant in the peaceful Tanat Valley. There's also a pretty 18th-century restaurant and tearoom, along with camping and self-catering accommodations, on-site. It was near here that, in 1588, the Bible was translated into Welsh—one of the key moments that helped to ensure the survival of the language.

Dating from 1576, Plas Mawr is one of the best-preserved Elizabethan town houses in Britain. Richly decorated with ornamental plasterwork, it gives a unique insight into the lives of the Tudor gentry and their servants.

On the very tip of a thumb-shape bay jutting out into the Irish Sea, this miniscule but gorgeous little harbor community is 20 miles from Porthmadog. There's a wide, sheltered beach where the sand is so fine that it squeaks underfoot, and whitewashed cottages line the curving seafront. Park at the nearby visitor center, one mile from the beach.

In Memorial Gardens, this museum tells the story of the town's development from prehistory onward and includes a small collection of Roman and medieval artifacts. The largest and most interesting section is devoted to the town's Victorian heyday, with some of the "cures" at the spa explained in detail.

Impressively complete from the front, majestically ruined within, Raglan was built in the 15th century and was the childhood home of Henry Tudor (1457–1509), who seized the throne of England in 1485 and became Henry VII. Raglan's heyday was relatively short-lived. The castle was attacked by Parliamentary forces in 1645, during the English Civil War, and has lain in ruins ever since. The hexagonal Great Tower survives in reasonably good condition (you can climb to the top), as do a handful of rooms on the ground floor.

The military exhibits here span centuries of conflict; some relate to battles in which this famous regiment and its Welsh predecessors participated. There's a vast collection of militaria, which is of interest mostly to fans of military history. The 3,000 or so medals on display include copies of 16 Victoria Crosses (the British equivalent of the Purple Heart) owned by the regiment. The Zulu Room recalls the defense of Rorke's Drift in the Anglo-Zulu war of 1879, an action dramatized in the 1964 film Zulu.

You can tour the local jail, where from 1654 to 1916 thousands of prisoners were incarcerated, and learn about prison conditions in Victorian times.

Outside the village of Ponterwyd, 10 miles east of Aberystwyth, this 200-year-old silver-lead mine is now a museum where you can tour reproductions of mining buildings and some original machinery, including working waterwheels. Kids over the age of eight can also enjoy a few harmless scares on the Black Chasm ghost tour, though very young ones will be better off sticking to the Woo Hoo Woods adventure playground. It's cold in the mine, even on hot days, so bring a jacket or sweater. Times can vary; call to check, especially in the off-season.

What is said to be Britain's smallest house is furnished in mid-Victorian Welsh style. The house, which is 6 feet wide and 10 feet high, was reputedly last occupied in 1900 by a fisherman who was more than 6 feet tall.

Swansea's covered market, part of the Quadrant Shopping Centre, is one of the best fresh-foods markets in Wales. In 2024, it was was even voted Best Large Indoor Market at The Great British Market Awards. You can buy cockles from the Penclawdd beds on the nearby Gower Peninsula, and laverbread, that unique Welsh delicacy made from seaweed, which is usually served with bacon and eggs.

Founded in 1841, this museum contains a quirky and eclectic collection that includes an Egyptian mummy, local archaeological exhibits, and the intriguing Cabinet of Curiosity, which holds artifacts from Swansea's past. In 2016, a forgotten Flemish masterpiece by Jacob Jordaens (1593–1678) was discovered in the museum's storeroom and is now on show.
