36 Weird & Wacky Things to Do in Wales You Won’t Believe

Wales is one of the strangest, most eccentric and gloriously unpredictable countries in the world. Alongside the castles and beaches there is a world of bizarre attractions, record-breaking oddities and only-in-Wales experiences that you simply will not find anywhere else on earth. From the longest place name on the planet to underground trampolining and cheese-rolling festivals, here are 36 weird and wonderful things to do in Wales in 2026.

Records, Place Names & Pure Welsh Eccentricity

1. Photograph One of the World’s Longest Place Names

Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch on Anglesey holds the record for the longest place name in Europe and the second longest in the world — 58 letters that roughly translate as “the church of St Mary in the hollow of white hazel trees near the rapid whirlpool by St Tysilio’s of the red cave.”

The train station sign is one of the most photographed in Britain. The village is on the A5 in Anglesey; pop into the tourist information centre inside the station for a certificate proving you visited.

2. Visit Portmeirion — Wales’s Italian Village

An entire Italianate village built from scratch on the Gwynedd coast by one eccentric architect over 50 years — Portmeirion is one of the most surreal places in Britain. In 2026 it celebrates its centenary. Day tickets required; entry from around £15 per adult.

3. Find Dinosaur Footprints on a Welsh Beach

Barry Island in the Vale of Glamorgan is the unlikely location of some of the best-preserved dinosaur footprints in Europe. At low tide on the beach west of the main sands, 220-million-year-old three-toed tracks left by early dinosaurs are visible in the exposed limestone shelf.

Free to access; check tide times before visiting as they are only visible at low water.

4. Cross the Pontcysyllte Aqueduct by Narrowboat

The Pontcysyllte Aqueduct near Llangollen is a UNESCO World Heritage Site — a cast iron trough carrying the Llangollen Canal 38 metres above the River Dee on 19 stone pillars. Narrowboat hire companies operate trips across it; or you can walk the towpath alongside.

There is no rail on the towpath side, making the experience memorably vertiginous. One of the finest pieces of industrial engineering in Britain.

5. Go Bog Snorkelling at the World Championship

The World Bog Snorkelling Championship takes place every August Bank Holiday Monday at Waen Rhydd peat bog near Llanwrtyd Wells in Mid Wales — the self-proclaimed “smallest town in Britain.” Competitors in wetsuits and snorkels complete two lengths of a water-filled trench cut through a peat bog without using conventional swimming strokes. Entry from around £20. Spectators welcome free.

6. Attend the World Alternative Games, Llanwrtyd Wells

The same town hosts the World Alternative Games every two years — a programme including bog snorkelling, man vs horse marathon, wife carrying, worm charming and tin bath racing. Llanwrtyd Wells has elevated the competitive absurd to a genuine art form.

Check the town’s events calendar for 2026 dates.

Underground Adventures

7. Trampoline Underground at Zip World Caverns

Zip World Slate Caverns in Blaenau Ffestiniog contains the world’s largest underground trampoline park and bounce below — hidden inside the vast 19th-century slate caverns that once produced the roofing slates for a quarter of the world.

The caverns also have zip lines, a subterranean bar and an eerie natural cathedral feel to them. Pre-booking essential; prices from around £20 per person for the bounce below.

8. Descend a Real Coal Mine at Big Pit

Big Pit National Coal Museum in Blaenavon is one of the finest free museums in the UK — a UNESCO World Heritage Site where former miners take visitors 90 metres underground in a real cage lift through actual mine workings.

The underground tour lasts around an hour. Completely free admission. Among the most genuinely moving experiences in Wales.

9. Explore the Largest Slate Caverns in the World

Llechwedd Slate Caverns in Blaenau Ffestiniog — separate to Zip World — offer traditional Victorian-era tours of the original slate mining workings, descending by the UK’s steepest passenger railway.

The mountain of waste slate that surrounds the town gives Blaenau Ffestiniog its extraordinary moon-landscape appearance.

Open daily; tours from around £22 per adult.

10. Tour the Largest Copper Mine in the Roman Empire

The Great Orme Mines on the headland above Llandudno contain the largest known prehistoric copper mine in the world — worked for over 3,500 years from the Bronze Age through to the Roman period.

The underground tour reveals original Bronze Age mining tools, 4,000-year-old bone and stone implements, and tunnels so small that only children can access some sections.

Open March–October; from around £12 per adult.

11. Visit Sygun Copper Mine, Eryri

Sygun Copper Mine near Beddgelert in Eryri (Snowdonia) is a former Victorian copper mine with spectacular stalactite and stalagmite formations and natural underground chambers.

An audio-visual tour winds through the mountain — genuinely impressive even for sceptics of “heritage mine” experiences.

From around £14 per adult.

Speed, Adrenaline & World Records

12. Ride the World’s Fastest Zip Line

Zip World Velocity at Penrhyn Quarry in Bethesda holds the world record for the fastest zip line — reaching speeds of over 100mph across the vast crater of the former slate quarry.

The four-person Titan is also available at the same site. Minimum age 16. From around £60 per person. Bookings sell out months in advance — plan well ahead.

13. Take the Steepest Street in the World

Ffordd Pen Llech in Harlech holds the Guinness World Record for the steepest street in the world — with a maximum gradient of 37.45%. It is genuinely alarming on foot; the view down towards Cardigan Bay is spectacular compensation.

Free to walk; located in the centre of Harlech near the castle.

14. Coasteer Where It Was Invented

Coasteering — swimming, scrambling and cliff-jumping along sea cliffs — was invented in Pembrokeshire in the 1980s and the national park coast remains the world’s finest venue.

Qualified guides take groups of all ages through caves, channels and sea stacks along some of Britain’s most dramatic coastline.

From around £40 per person; various operators in St Davids, Tenby and Pembroke.

See coasteering operators →

15. Race a Horse (Man vs Horse Marathon)

The Man vs Horse Marathon in Llanwrtyd Wells pits human runners against horses and riders over a 22-mile cross-country course through the Cambrian Mountains every June.

Humans have won just three times in the race’s 45-year history.

Open to runners of any ability; entry from around £30. Spectators free.

Ghosts, Legends & Dark History

16. Spend a Night in a Haunted Castle

Several of Wales’s 600-plus castles are available for overnight stays — and some have significant haunting reputations.

Soughton Hall in Flintshire, Craig y Nos Castle in the Brecon Beacons and Ruthin Castle in Denbighshire all offer overnight ghost experiences and have documented paranormal histories.

Ruthin Castle is particularly notable for its medieval banquets and ghost walks.

17. Follow the Legend of Gelert in Beddgelert

The legend of Gelert — a faithful hound killed by his master Llywelyn the Great in a tragic misunderstanding after saving his baby son from a wolf — is one of the most poignant stories in Welsh folklore. The supposed grave of Gelert is a short riverside walk from the centre of Beddgelert village. The legend was probably invented by an 18th-century innkeeper to boost tourism — which makes it arguably the first successful piece of Welsh travel marketing.

18. Visit the Town That Declared War on the World

Hay-on-Wye declared independence as “The Kingdom of Hay” in 1977 when the eccentric Richard Booth crowned himself King. The declaration was entirely tongue-in-cheek but brought enormous publicity to what is now the world’s second-hand bookshop capital.

A small bronze plaque in the town marks the seat of the former “kingdom.” Boost your visit with a trip to the Hay Festival in May/June — one of the world’s great literary events.

19. Hunt for the Loch Ness Monster’s Welsh Cousin

Llyn Tegid (Bala Lake) — the largest natural lake in Wales — is said to be home to Teggie, a lake monster of disputed description and entirely unverified existence.

The lake is over 4 miles long and 140 feet deep, giving Teggie ample hiding room. Take the narrow-gauge Bala Lake Railway along the shore for the best monster-spotting vantage points.

20. Find the Smallest House in Great Britain

The Quay House in Conwy holds the official record as the smallest house in Great Britain — just 72 inches wide, 122 inches tall and 120 inches deep, with two tiny rooms stacked vertically. It was last occupied in 1900 by a fisherman who was reportedly 6 feet 3 inches tall.

Entry around £2 per person. Located on the Conwy quayside, yards from the castle.

Dark Skies, Science & the Unexplained

21. Stargaze at One of Europe’s Best Dark Sky Parks

The Elan Valley in Mid Wales is an International Dark Sky Park — one of the darkest places in Britain, with minimal light pollution and extraordinary views of the Milky Way on clear nights.

The site now has a brand new planetarium (opened 2026) with regular stargazing events and shows. Book through the Elan Valley Visitor Centre. Accommodation in the area fills up fast on new moon weekends.

22. Visit the “Bermuda Triangle of Wales”

The Berwyn Mountains in North East Wales have been the site of numerous reported UFO sightings, unexplained lights and a controversial 1974 incident known as the “Welsh Roswell” — when a large explosion, lights in the sky and a tremor were reported simultaneously.

The Berwyns are a genuinely remote and atmospheric upland, excellent for walking regardless of your views on extra terrestrial activity.

23. Attend the National Eisteddfod — Europe’s Largest Festival in a Minority Language

The National Eisteddfod is one of Europe’s oldest cultural festivals and the largest gathering conducted almost entirely in Welsh — a language spoken by around 900,000 people.

Poetry, music, drama, art and craft competitions take place across eight days in a purpose-built tented city that moves to a different location each year. Unique, genuinely moving and surprisingly accessible for non-Welsh speakers.

August dates confirmed; location announced annually.

24. Find the Drowning Kingdom of Cantre’r Gwaelod

At very low tides on the beach north of Borth in Ceredigion, the submerged stumps of an ancient Bronze Age forest are exposed — the physical remains of a coastline that was flooded by rising seas around 4,500 years ago.

Welsh mythology calls this Cantre’r Gwaelod, a lost kingdom beneath the waves. The stumps are eerie and haunting; best visited at spring low tides.

Check local tide tables before visiting.

Only-in-Wales Food, Drink & Traditions

25. Eat a Welsh Cake Straight from the Griddle in Cardiff Market

Cardiff’s Victorian Market — one of Europe’s finest covered markets — has a stall producing Welsh cakes on a traditional cast-iron bakestone. Bought warm, with butter, they are one of the finest things you can eat in Wales.

The market also sells laverbread (a seaweed paste, technically a superfood) and cockles from the Gower. Free to browse; Welsh cakes cost around £1.50 each.

26. Drink Welsh Single Malt Whisky at Penderyn Distillery

Penderyn Distillery in the Bannau Brycheiniog (Brecon Beacons) produces internationally award-winning Welsh single malt whisky — a product that many people don’t know exists and even fewer expect to be any good. It is.

Distillery tours run daily from around £20 per person, including tastings of multiple expressions. A Visitor Centre shop sells the full Penderyn range plus Welsh gin and vodka.

27. Eat Laverbread — the “Caviar of Wales”

Laverbread (bara lawr) is a seaweed paste made from laver seaweed gathered on the Welsh coast, cooked for hours and rolled in oatmeal before frying. It has the appearance of something dredged from a pond but the taste is deeply savoury and the nutritional profile extraordinary.

Try it at the Swansea Market — the finest laverbread in Wales — served on toast with cockles and bacon for a traditional Welsh breakfast.

28. Watch a Coracle Race on the River Teifi

The coracle — a small, round, one-person boat made from woven willow and animal hide — has been used for fishing on Welsh rivers for over 2,000 years and is one of the oldest watercraft designs in the world.

Coracle regattas still take place on the River Teifi near Cenarth. The Cenarth Falls waterfall and a working flour mill are also worth seeing at the same stop.

Transport Eccentricities & Engineering Marvels

29. Ride the World’s Only Cable-Hauled Street Tramway

The Great Orme Tramway in Llandudno is the only remaining cable-hauled street tramway in Britain and one of only a handful left in the world. Victorian-era trams are hauled up the Great Orme headland by an underground cable at a stately 4mph.

Running since 1902; from around £10 return. Spectacular views across Conwy Bay at the top.

30. Take the Snowdon Mountain Railway — Britain’s Only Rack-and-Pinion Railway

The Snowdon Mountain Railway climbs Yr Wyddfa (Snowdon) from Llanberis to the summit at 1,085 metres on Britain’s only public rack-and-pinion railway — a Swiss-style system where a toothed rack rail prevents the train from sliding backwards.

The summit café and visitor centre have panoramic views across Wales, England and Ireland on clear days. From around £47 return; pre-booking essential.

31. Cross the Longest Cycle Viaduct in Wales at Pontarddulais

The Gowerton to Llanelli section of the National Cycle Network crosses the Loughor Viaduct — over 2,000 feet of elevated cycling above the Loughor Estuary with views across to the Gower Peninsula.

An unexpected and spectacular cycling experience in South Wales. The route connects to the Millennium Coastal Path.

32. Ride the Ffestiniog Railway — Oldest Independent Railway Company in the World

The Ffestiniog Railway has been operating continuously since 1836 — making it the oldest independent railway company in the world. The narrow-gauge steam railway runs 13 miles from Blaenau Ffestiniog to Porthmadog through some of the finest scenery in Eryri (Snowdonia).

Combined with the Welsh Highland Railway, you can travel from Caernarfon to Porthmadog via Beddgelert entirely by narrow-gauge steam. From around £27 single.

Festivals, Events & Cultural Quirks

33. Attend a Six Nations Match at the Principality Stadium

Welsh rugby at the Principality Stadium in Cardiff on a Six Nations day is one of the great sporting experiences in the world — 74,500 people in a retractable-roof city-centre stadium, singing in four-part harmony, with the crowd noise bouncing off the closed roof to create something genuinely spine-tingling.

Wales vs England and Wales vs Ireland are the fixtures to aim for. Tickets from around £60; sell out within minutes of release.

34. Go to the Largest Scarecrow Festival in Wales

The Presteigne Scarecrow Festival in Powys transforms the small border town into a gallery of increasingly elaborate and competitive scarecrow art across an August bank holiday weekend — hundreds of handmade figures filling every garden, doorstep and lamppost.

Free to browse; one of the most joyful and unpretentious events in the Welsh calendar.

35. Try to Complete the Three Peaks Challenge

The National Three Peaks Challenge — climbing the highest peaks in Scotland, England and Wales within 24 hours — includes Yr Wyddfa (Snowdon) as the Welsh leg.

Snowdon alone is a full day for most walkers; those attempting the full Three Peaks treat it as the final challenge after Ben Nevis and Scafell Pike. A genuine test of endurance — and Wales gets to finish off the finest walkers in the UK. See walking guides in Wales →

36. Spot the Most Red Kites in One View Anywhere on Earth

Wales saved the red kite from British extinction — in the 1990s just a handful of breeding pairs remained in the Cambrian Mountains. The conservation programme was so successful that Mid Wales now has the highest density of red kites in the world.

At Gigrin Farm near Rhayader, hundreds descend to a daily feeding session at 2pm (3pm summer). Watching 400 red kites in the sky simultaneously is one of the most epic wildlife spectacles in Europe. Entry around £8 per adult.

Plan Your Weird & Wonderful Wales Adventure

Frequently Asked Questions: Weird & Wacky Wales

Where is the most haunted place to stay in Wales?

Craig y Nos Castle in Swansea is widely considered the most haunted castle in Wales. Once a TB hospital and the home of opera singer Adelina Patti, it offers ghost tours and overnight stays. Another legendary spot is the Skirrid Mountain Inn in Abergavenny, which features an oak hanging beam used during its dark history as a courtroom.

Where is the smallest house in Great Britain?

The smallest house in Great Britain, known as Quay House, is located on the quayside in Conwy. Measuring just 10ft deep by 6ft wide, this tiny red building was a fisherman’s residence until 1900. Visitors can still step inside the ground floor to see just how compact 16th-century living really was.

Are there real dinosaur footprints on a Welsh beach?

Yes! You can walk in the footsteps of prehistoric giants at Bendricks Beach in Barry, South Wales. The beach contains well-preserved three-toed dinosaur footprints from the Triassic period. There are no signs pointing them out, so finding them is part of the “wacky” adventure.

What is the Mari Lwyd Welsh tradition?

The Mari Lwyd is a unique and slightly creepy winter tradition, mostly found in South Wales. It involves a group carrying a decorated horse’s skull on a pole, draped in white sheets, to neighbors’ doors. They engage in a “pwnco”—a battle of rhyming wits and songs—to win entry for food and drink.

Can you jump on trampolines inside a Welsh mine?

Absolutely. “Bounce Below” is a subterranean playground located in a massive abandoned slate mine at Blaenau Ffestiniog, Snowdonia (Eryri). It features giant trampolines and nets suspended in caverns at heights of up to 180ft, accessible via an old mine train.

Most of the attractions on this list are spread across Wales — making a road trip the ideal way to tick off as many as possible.
