Snowdonia

From the visitor car park, the entry path slips through a tunnel of subtropical rhododendron before opening — without warning — onto a pastel campanile rising above the Dwyryd estuary. Sir Clough Williams-Ellis spent fifty years from 1925 piecing this Italianate fantasy together to prove that 'development could enhance natural beauty'; Patrick McGoohan filmed The Prisoner here in 1967 and the village has been a pilgrimage site ever since. At 09:00 you have the central piazza and the Bristol Colonnade essentially to yourself — the coach parties from Liverpool arrive after 11:00.

Tip: Walk the Gwyllt woodland trails first while everyone else photographs the piazza — the Chinese Lake and the dog cemetery beyond it are the parts most visitors miss entirely. By the time you loop back at 10:30, the central village is at peak light with the sun finally over the campanile, and most early-bird tourists have already drifted to the gift shop.

A five-minute uphill walk through Portmeirion's upper gate brings you to a crenellated Victorian folly castle on the headland — the brasserie occupies the original 1850 stone hall. The kitchen takes mussels from the estuary you're looking at (£14) and lamb from the farm three miles inland (£22); the bara lawr (laverbread) with cockles starter (£11) is the dish most British restaurants have stopped attempting. Two courses with a glass of Welsh wine runs around £30.

Tip: Request a table on the south-facing terrace, not in the panelled dining room — you'll eat with the entire Dwyryd estuary and Cnicht peak on the horizon. The set lunch menu is £24 for two courses but isn't advertised at the door; ask specifically when you sit down.

A 25-minute drive northeast on the A487 lifts you into Blaenau Ffestiniog — the slate-roof town that 'roofed the 19th-century world' and gained UNESCO World Heritage status in 2021. Britain's steepest cable railway drops you 152 metres underground into Victorian caverns the size of cathedrals; your guide is invariably a former quarryman or his son. The original 1846 working faces, illuminated only by miners' lamps, show the slate-vein in its natural geometry — there is nothing else like it in Europe.

Tip: Wear a fleece even in August — the caverns hold steady at 7°C year-round and the stone seats are colder than that. Pick the 14:00 tour specifically: the 15:00 and 16:00 slots back up with school groups, and the 14:00 guide (typically Trevor, who quarried here for 41 years) is the one who'll show you the hidden 'singing slab' that rings like a bell when struck.

Ten minutes' drive west of Llechwedd, the road slips around the shoulder of Moelwyn Mawr and drops to Tanygrisiau — a black mirror of a reservoir flanked by abandoned slate-terrace tips that shimmer almost silver in afternoon sun. The narrow mountain road climbs another mile to the Llyn Stwlan dam at 510 metres; from the dam wall you look back across the entire UNESCO slate landscape with the Moelwynion ridge rising behind. By 17:00 the light goes from gold to oxidised copper on the spoil heaps — it is the most cinematic free view in north Wales.

Tip: The Stwlan dam road is a private single-track lane with no passing places for the final mile — go slow and check for descending cars at every blind corner. Walk the last 100 metres on foot from the small pull-in rather than driving to the wall itself; the angle from the path is dramatically better and you won't block other photographers.

A scenic 25-minute drive northwest through the Aberglaslyn Pass — the most photographed gorge in Wales — drops you into Beddgelert, a stone-bridge village at the confluence of two rivers where the Glaslyn rushes over boulders right beside the high street. The village name means 'Gelert's Grave', after the legendary 13th-century hound of Prince Llywelyn the Great buried in the meadow south of the bridge. Early evening, when the day-trippers have gone, the village reverts to its proper rhythm: Welsh spoken in the shops, swallows over the river, the smell of woodsmoke from the inns.

Tip: Cross the old stone bridge and follow the Glaslyn riverside footpath south for five minutes to Gelert's Grave itself — almost no tourist makes it past the bridge. From the grave you see the village from the angle every postcard uses, with Mynydd Sygyn rising behind the slate roofs.

Two minutes' walk from Gelert's Grave back across the bridge to the village square, the white-washed Tanronnen has been the village inn since 1809 and is the place farmers from the surrounding hills actually drink. The kitchen is firmly traditional — slow-cooked Welsh lamb shank with rosemary jus (£22), pan-fried local trout with brown butter (£20), and a sticky toffee pudding (£8) the village remembers older than any of the diners. Welsh ales on tap include Cwrw Llyn from up the coast.

Tip: The front bar serves the same kitchen as the dining room but with no reservation required and proper local atmosphere — locals drink at the right-hand end by the fire. Avoid the two tea-rooms on the main street through Beddgelert: both close at 17:00 and any 'evening menu' offered by their attached cafés in summer is reheated pub fare at tourist prices. Never buy anything from the lay-by 'Welsh Crafts' vans on the A498 leaving the village; the slate coasters are imported from Spain.

Drive 30 minutes south to Blaenau Ffestiniog — Llechwedd's Victorian mine entrance opens straight into the side of the mountain on the town's eastern flank. The Deep Mine Tour descends 150 m on Britain's steepest cable railway (1:1.8 gradient) into chambers the size of cathedrals, lit by carbide lamps the way 1846 miners worked them. This is one of the six inscribed sites of the UNESCO Slate Landscape of Northwest Wales (2021).

Tip: Book the 09:30 first tour — the chambers are still cool and you skip the school groups that arrive after 11:00. Wear long sleeves: the mine is 10°C year-round even in July, and the cable car descent is wet from condensation.

Drive five minutes back down into Blaenau — Cellb sits in the Victorian police station opposite the railway station, the original cells now a community bar and bistro. Lunch in the magistrates' courtroom under the judge's bench, Welsh rarebit (£9) and slow-braised beef cheek (£15) the kitchen does properly. Half the menu is in Welsh first, English second — this is one of the most deeply Welsh-speaking towns in the country.

Tip: Order the bara brith pudding with Penderyn whisky cream — Penderyn distils Wales' only single malt and the kitchen reduces it into a treacly sauce. Tip in cash if you can — it goes straight to the staff, not into a tronc.

Cross the station forecourt — the Ffestiniog platform is on the lower level. Opened in 1836 to haul slate down to Porthmadog harbour, this is the world's oldest narrow-gauge railway and the engines pulling you today were built before 1879. Take the 14:00 train down to Tan-y-Bwlch (35 minutes), step off for the woodland viewpoint over the Vale of Ffestiniog, and catch the 16:00 return back up to Blaenau.

Tip: Pay the +£8 first-class supplement — the observation car at the back has rear-facing windows and you watch the line curve away behind you through the slate cuttings. Bring a jacket: even in July the carriages have open windows by design, and the speed cools you fast.

From Blaenau station, the road climbs five minutes west to Tanygrisiau — a hydroelectric reservoir cupped between slate-stripped peaks with the lost village of Cwmorthin abandoned on the slope above. Walk the eastern shore for thirty minutes: by 17:30 the slate spoil heaps catch the low sun and turn deep purple, the local slate's true colour. Save another 30 minutes to wander the dam's edge if energy allows.

Tip: The 'Lost Village' walk to Cwmorthin starts from the reservoir's north end — a 25-minute climb to the ruined chapel and chapel-house, with no signage on purpose. The original 1860s roof slates still lie where they fell; leave them where they are, the rangers do walk this path.

Ten minutes' drive south of Tanygrisiau, the Grapes is a 1730 coaching inn on the old London-Holyhead road — Lloyd George and Lillie Langtry both ate at the same staging post. Welsh black beef sirloin (£28) comes with bone marrow gravy, and the daily fish landed at Aberdyfi depends on what the boat brought in. Three small dining rooms inside the original stone walls — ask for the snug at the back with the open fireplace.

Tip: Start with the Welsh cawl (£9) — slow-cooked lamb broth with leeks and root veg, the kitchen makes a fresh pot every morning. Pitfall: the bar at the front serves cheaper pub food off a separate menu — ask for the restaurant menu when you sit down, the kitchen is the same but the cuts are not.

Drive 30 minutes south-west from your base — arrive at Portmeirion as the gates open at 09:30 and the village is yours. Clough Williams-Ellis spent 50 years (1925-1975) building this Italianate folly on a private peninsula, salvaging columns and arches from demolished mansions across Britain. Walk the Bristol Colonnade, the Piazza, and the woodland Gwyllt path down to the white sand of Traeth y Greigddu — The Prisoner was filmed across every corner of this village in 1966-67.

Tip: Buy entry online the night before (£17) and head straight to the Pantheon dome — the photo line forms there by 11:00 and you'll have it to yourself for the first hour. Skip the gift shops in the centre square; the architectural salvage shop down by the hotel is where the real finds are.

Walk five minutes back up to the gatehouse — Castell Deudraeth is the castellated mansion just outside Portmeirion's main entrance, within the same Williams-Ellis estate. Lunch is Cardigan Bay sea bass with cockles and laverbread (£22), or the Portmeirion smoked salmon platter (£18) cured on-site. The conservatory dining room looks straight onto the Dwyryd estuary at low tide.

Tip: Reserve the noon slot specifically — the kitchen receives the tide-fresh shellfish delivery at 11:30 and the first lunch service gets first pick. Ask for the Penderyn-cured salmon, only made for this kitchen and not on the printed menu.

Drive 25 minutes north — Beddgelert sits at the meeting of three rivers under the shoulder of Moel Hebog, dark stone houses and slate roofs huddled around the bridge. Walk the riverside path 800 m south of the village to Gelert's Grave: the legendary 13th-century hound of Llywelyn the Great, wrongly killed for protecting his master's child from a wolf. The grave itself is fictional Victorian marketing — but the meadow it stands in, with Yr Aran framing the view, is the real Wales.

Tip: Stop at Glaslyn Ices on the main street (the blue-fronted shop) — the third generation of the Williams family make the ice cream in the back room every morning. The honeycomb is the local order; the vanilla uses milk from the dairy two miles up the road.

From Gelert's Grave, the Fisherman's Path continues 1.6 km south through the Pass of Aberglaslyn — voted one of the most beautiful gorges in Britain. Rock-hewn ledges, river pools beneath you, and the woodland canopy closing overhead; turn back at the Pont Aberglaslyn bridge and retrace the path. The afternoon light comes through the pines at a low angle and lights the water gold against the black slate walls.

Tip: The narrow ledge section 400 m in has metal handholds bolted into the rock — the path is safe but two-way traffic stops; let oncoming walkers through, don't try to squeeze past. Skip this in heavy rain: the ledges run with water and turn slick on slate.

Walk back into Beddgelert — Tanronnen is the white-fronted inn on the main square, run by the same family for forty years. The Welsh lamb shoulder slow-cooked for seven hours (£26) is what locals come back for, and the Snowdonia gin tonic (£8.50) uses a botanical foraged from Cwm Idwal up the road. Eat in the slate-floored front room with the wood-burning stove if it's free.

Tip: Order the Welsh rarebit starter (£8) — a 1972 recipe with Black Mountain cheddar and Felinfoel ale that no menu in Wales will print. Pitfall: avoid the 'Beddgelert Brewery' tap-room down the street that opens for coach tours — the food is microwave reheat, not made on premises like Tanronnen's, and the markup on the local ales is double.
