Gwynedd and Conwy, Wales · United Kingdom
Wales's mountainous heart: a national park of jagged peaks and slate-grey lakes, ringed by castles built to hold the country down and a coastline that rewards anyone who reaches it.

Snowdonia — Eryri in Welsh, the name now officially used alongside the English one — is a national park built around Yr Wyddfa, Wales's highest mountain at 1,085 metres, and the jagged, glacier-carved range surrounding it. It is mountainous in a way little else in England or Wales quite matches, with real scrambling routes, sharp ridgelines and weather that turns fast.
The park sits within a wider region shaped by two very different forces: Edward I's 13th-century castle-building campaign, which left Conwy and Caernarfon among the most complete medieval fortresses in Europe, and the 19th-century slate industry, which built entire towns like Blaenau Ffestiniog and Llanberis around quarrying the mountains themselves.
The coastline nearby is an underrated part of the trip — the Llŷn Peninsula and Anglesey offer beaches and cliff walks that feel a world away from the mountains just inland, and the combination of the two in one compact region is a large part of what makes North Wales worth the distance from England's south.
Why visit
Snowdonia's case is that nowhere else in England or Wales packs genuine mountain scrambling, complete medieval castles and a dramatic coastline into one manageable region.
Yr Wyddfa and its neighbouring ridges offer real scrambling and exposed terrain, a different order of challenge from most English hill walking.
Conwy and Caernarfon, both UNESCO-listed, survive largely intact — a rare thing for medieval fortresses this old.
Entire mountainsides and towns were shaped by an industry that literally quarried the landscape, now preserved rather than erased.
Anglesey and the Llŷn Peninsula add beaches and sea cliffs that most mountain-focused visitors don't expect to find so close by.
Welsh is widely spoken as a first language here, giving the region a distinct cultural identity rather than feeling like an extension of England.
Main attractions
A mix of mountain, castle and heritage sights that together capture the different sides of this region.
Wales's highest peak at 1,085 metres, reachable by several walking routes or the Snowdon Mountain Railway, with views stretching to Ireland on a clear day.
Tip The Llanberis Path is the longest but gentlest route; the Pyg Track and Miners' Track are more scenic but steeper.
A UNESCO World Heritage castle built by Edward I in the 1280s, its eight towers and largely intact walls forming one of the most complete medieval fortresses in Britain.
Tip Walk the town walls, also largely intact, for a free and dramatic view over the castle and estuary.
Another Edward I fortress, built partly to evoke Constantinople's walls and used for the investiture of the Prince of Wales, among the most imposing castles in Britain.
Tip Climb the towers for views over the Menai Strait toward Anglesey.
A former slate-quarrying town at the foot of Snowdon, now a UNESCO World Heritage site telling the story of the industry that shaped the region's mountains and towns.
Tip The National Slate Museum, in a former quarry workshop, is free to enter and well presented.
An eccentric, brightly coloured Italianate village built by architect Clough Williams-Ellis over five decades, unlike anywhere else in Wales.
Tip Famous as the filming location for the 1960s TV series The Prisoner, still celebrated by an annual fan festival.
A quieter coastal side to the region, with beaches, cliff walks and the pilgrimage island of Bardsey off the Llŷn, and South Stack's cliffs on Anglesey.
Tip Both reward at least a full day — they are different in character from the mountainous interior.
Things to do
Beyond the headline sights, this region rewards a mix of mountain activity and slower coastal and heritage time.
Reaching the summit on foot, or by the historic Snowdon Mountain Railway for those not up for the climb, is the region's central experience.
Tip Book the railway well ahead in summer — it sells out, and walking remains free and available regardless of ticket availability.
Former slate quarries near Llanberis and Blaenau Ffestiniog have been repurposed into inventive attractions — Europe's fastest zip line and vast underground trampoline networks.
Tip Both require advance booking and are hugely popular in school holidays.
Both towns retain substantial medieval walls, walkable for free and giving excellent views over the castles and surrounding water.
Tip Conwy's walls form a more complete circuit than Caernarfon's — allow about an hour to walk the full loop.
Former working slate mines, particularly around Blaenau Ffestiniog, now offer underground tours giving a genuine sense of the industry's scale and conditions.
Tip Bring a jacket — the caverns stay cool year-round regardless of the weather outside.
A quieter, more remote coastline than much of Wales, with beaches like Porth Oer (Whistling Sands) and dramatic cliff walks around Aberdaron.
Tip The peninsula's far end feels remote — allow more driving time than distances alone suggest.
North Wales has a strong network of narrow-gauge heritage railways, including the Ffestiniog and Welsh Highland lines through dramatic mountain scenery.
Tip The Ffestiniog Railway is one of the oldest surviving railway companies in the world, dating to 1832.
Local food
Welsh food leans on hearty mountain and coastal traditions, with a few distinctive national dishes.
A rich, mustard- and ale-spiked cheese sauce grilled onto toast, more elaborate than simple cheese on toast and a genuine national dish.

Where to try it Markets and cafes throughout Wales, often cooked fresh in front of you.
Conwy's estuary has produced mussels for centuries, and the town's harbour restaurants serve them fresh, often simply steamed with local ingredients.
Where to try it Harbourside restaurants in Conwy, particularly in the mussel season from September to March.
North Wales has a growing craft brewing scene alongside traditional cask ales, with several breweries producing distinctive local beers.
Where to try it Traditional pubs across the region, several serving beer from breweries within a short distance.
Accommodation
Llanberis and Betws-y-Coed are the two main mountain bases, with Conwy a good alternative for those prioritising the coast and castles.
Transport
Manchester and Liverpool are the nearest major airports, with a car useful once inside the region.
A car is close to essential for covering the region's mountains and coastline together, though buses reach the main towns.
When to go
Snowdonia's weather is changeable in any season, making daylight hours and crowd levels the more reliable planning factors.
Lengthening daylight, waterfalls at their fullest, and crowds well below the summer peak on the main trails.
The busiest months, with Yr Wyddfa's main paths and the Mountain Railway crowded, though the longest daylight for hiking.
Comfortable temperatures, thinning crowds, and often some of the year's clearest, most photogenic days on the mountains.
Wintry on the higher peaks, with snow and ice requiring proper equipment and experience for anything beyond the valleys.
Worth planning around: Bank holiday weekends in summer, when Yr Wyddfa's main car parks and paths become overcrowded.
Itinerary
The mountain first, then castles and slate heritage, with a coastal day to close — a loop that covers the region's different sides.
The region's central experience.
The industry that shaped the region, and its most eccentric village.
Two of Edward I's greatest castles.
A final, quieter coastal day.

FAQ
Three to four. Three covers Yr Wyddfa and the main castles; four adds proper time for the coast or the slate heritage sites without feeling rushed.
No — the Llanberis Path is a long but non-technical walk manageable by reasonably fit beginners, and the Mountain Railway offers a non-hiking alternative. The Pyg Track and Crib Goch are more serious and better suited to experienced walkers.
May to June and September offer the best balance of decent weather, long daylight and manageable crowds. Summer is busiest on the main trails; winter requires proper equipment and experience above the valleys.
Largely yes, particularly for combining the mountains with the coast. The Snowdon Sherpa bus network covers the main trailheads well, but the wider region, including Anglesey and the Llŷn Peninsula, is far easier with a car.
Yes — North Wales has some of the highest rates of Welsh as a first language in the country, and bilingual signage is standard throughout.

Most packing advice is a list of things. This is the opposite: the small number of decisions that determine whether your luggage helps or hinders, organised by the kind of trip you are actually taking.
Transport
European rail is excellent and confusing — six national operators, three completely different pricing models, and a rail pass that is either a bargain or a waste depending on where you are going. Here is how to work out which.
