Welsh Highland Railway (Rheilffordd Eryri) Travel

The Welsh Highland Railway (Welsh: Rheilffordd Eryri) — the UK's longest heritage railway, a 25-mile (40km) narrow-gauge steam train line that departs from beside the medieval Caernarfon Castle, crosses the heart of Snowdonia National Park (Eryri), passes through the fairy-tale village of Beddgelert and the spectacular Aberglaslyn Gorge, and arrives at Porthmadog Harbour. The line uses giant Beyer-Garratt steam locomotives imported from South Africa — the most powerful steam locomotives ever built for 2-foot narrow-gauge railways. When they whistle through the gorge, smoke curling among the oak trees, you'll feel transported back to the golden age of Victorian railways. This is an epic slow journey from castle to harbour.

Highlights

Depart from Caernarfon station in the early morning — this modern station built in 2019 sits right next to the UNESCO World Heritage Caernarfon Castle. Board a wooden carriage handcrafted by the Ffestiniog Railway workshops, with a panoramic skylight overhead, and ahead looms the dark green, 80-tonne Beyer-Garratt NG/G16 steam locomotive — the most powerful steam locomotive ever built for 2-foot gauge, originally from South Africa, fully overhauled and reborn. The train slowly pulls out of the station, crossing the pastoral Traeth Mawr floodplain, passing the Dinas locomotive sheds (glimpse locomotives undergoing restoration), and arriving at Waunfawr station — with its community-tended flower beds and a welcoming country pub. Continuing to Rhyd Ddu station, the north face of Snowdon (Yr Wyddfa) suddenly appears outside the window — this is the starting point for the Rhyd Ddu Path up Snowdon. The train then runs along the shore of Llyn Cwellyn, the lake surface reflecting peaks and sky in a breathtaking mirror. By afternoon, you arrive at Beddgelert — a fairy-tale village haunted by the legend of Gelert, with a 1.5-hour stop to stroll along the river, visit Gelert's Grave, and sample award-winning Glaslyn Ices handmade gelato. The return or onward journey takes you through the most spectacular section of the entire line — the Aberglaslyn Gorge — as the train ducks through three rock tunnels and threads along a narrow ledge hanging above the river, with the Glaslyn River roaring below. Finally, you arrive at Porthmadog Harbour station, where the line meets the Ffestiniog Railway, ending the day's journey at Spooner's Café.

Attractions
Welsh Highland Railway (Rheilffordd Eryri) Full Journey
The UK's longest heritage railway, a 25-mile (40km) 2-foot narrow-gauge line from Caernarfon to Porthmadog crossing the heart of Snowdonia National Park. The line's history dates back to 1922, but the original line closed in 1937 due to financial difficulties and the track was dismantled in 1941. From the 1990s, the Ffestiniog Railway Company led a reconstruction effort, reopening in stages: Caernarfon-Dinas in 1997, Waunfawr in 2000, Rhyd Ddu in 2003, Beddgelert in 2009, and the full line to Porthmadog finally completed in 2011. The primary traction is the South African NG/G16 Beyer-Garratt articulated steam locomotive — a double-boiler design weighing 80 tonnes, the most powerful steam locomotive in the world for 2-foot gauge. Diesel locomotives supplement the service.
Fares (2026): The Harbourmaster (Porthmadog-Caernarfon full return) Adult £72, Child £5; The Aberglaslyn (Porthmadog-Beddgelert section return) Adult £43, Child £5; Gold Class first-class carriage (Pullman-style handcrafted carriage with seat service) requires a supplement. Online booking incurs a 6% handling fee but guarantees a seat.
Operating Period: Steam trains 4 May - 16 October; Diesel trains 28 March - 25 October. Advance online booking strongly recommended — peak season often sells out on the day.
Seven Major Stations: Caernarfon (northern terminus, adjacent to the castle) → Dinas (locomotive sheds and workshops) → Waunfawr (flower-bed platform + country pub) → Rhyd Ddu (Snowdon trailhead) → Beddgelert (fairy-tale village stop) → Pont Croesor (RSPB osprey observation flag stop) → Porthmadog Harbour (southern terminus, interchange with Ffestiniog Railway).
Caernarfon Castle & Historic Town
UNESCO World Heritage Site, a royal fortress-palace begun by Edward I in 1283, part of the "Castles and Town Walls of King Edward in Gwynedd" World Heritage Site alongside Conwy, Beaumaris and Harlech castles. The castle is most striking for its banded masonry (alternating layers of light and dark stone) and polygonal towers — a design inspired by the Theodosian Walls of Constantinople. It is the coronation site of the Princes of Wales, where Prince Charles was invested as Prince of Wales in 1969. The castle houses exhibitions on Welsh history and the investiture ceremony.
Tickets: Adult £15.60 (peak season Jun-Aug), off-peak £14.90; Cadw members free; 5% discount for online booking.
Surroundings: The castle sits right on the Menai Strait waterfront. The town features Y Galeri arts centre (with theatre and cinema), Villa Marina Italian restaurant (superb sea views above the castle), Black Boy Inn (16th-century historic inn, now restaurant + B&B), and Bar Bach (reportedly Wales' smallest pub, stocked with local gin and malt whiskies). You can also cycle the Lôn Eifion cycle path, a 10-mile dedicated cycle route running parallel to the railway.
Beddgelert Fairy-Tale Village & Aberglaslyn Gorge
Beddgelert — one of Snowdonia's most beautiful villages, with stone cottages scattered along both banks of the River Glaslyn, an ancient stone bridge spanning the emerald-green water, and mountains keeping silent watch in the distance. The village name derives from a legend: in the 13th century, Prince Llywelyn the Great's faithful hound Gelert killed a wolf to protect the prince's infant son, but was mistakenly slain by the prince himself. Overcome with remorse, Llywelyn buried his beloved dog outside the village and erected a memorial — "Beddgelert" means "Gelert's Grave."
Gelert's Grave Walk: From the stone bridge at the south end of the village, follow the river for about 10 minutes to reach the grave. A simple circular path maintained by the National Trust, flat and accessible, wheelchair and pushchair friendly, about 1 mile (1.6km) round trip, 40 minutes - 1 hour.
Aberglaslyn Gorge Walk: Starting from Beddgelert or the Nantmor car park heading south, follow the River Glaslyn through a narrow volcanic rock gorge, with railway tunnels and cantilevered rock ledges appearing alternately, the river roaring below — voted by National Trust members as "Britain's most breathtaking landscape." About 3km one way, 1.5-2.5 hours round trip, path is narrow with occasional iron ladders clinging to rock faces.
Village Amenities: Bistro Hebog (rating 4.7, duck breast and lamb dishes outstanding), Glaslyn Ices (award-winning handmade gelato, one of Wales' oldest independent gelato makers), Caffi Gwynant (riverside café outside the village, rating 4.8), Saracen's Head (17th-century historic inn).
Porthmadog Harbour & Ffestiniog Railway
Porthmadog — a thriving harbour town on the edge of Snowdonia National Park, reclaimed from the sea in 1811 by William Madocks who built the embankment (The Cob). In the mid-19th century, it was one of the world's most important slate export ports, with annual exports peaking at 140,000 tonnes. Today it is the meeting point of two legendary narrow-gauge railways.
Ffestiniog Railway: The world's oldest surviving narrow-gauge railway (founded in 1832), running from Porthmadog to Blaenau Ffestiniog, 13.5 miles, passing Tan-y-Bwlch station (famous tea room) and Llyn Ystradau reservoir, ending at Blaenau Ffestiniog — once the slate mining capital that "roofed the world." You can buy a combined "Snowdonia Single" through-ticket (£40.30) valid on both WHR and FR.
Spooner's Café: Located inside Harbour Station, named after railway pioneer Charles Spooner, serving hot meals, sandwiches and cakes. The terrace overlooks the railway line, offering an excellent position to watch steam trains arriving and departing.
Maritime Museum: Housed in the last surviving slate warehouse, telling the maritime and railway history of Porthmadog.
Purple Moose Brewery: Award-winning local craft brewery (founded 2005), whose bar The Australia serves their own draught beers and home-cooked food.
Black Rock Sands: 2 miles from town, a two-mile stretch of golden sand and dune system where you can drive onto the beach (pay attention to tide markers).
