Eryri (Snowdonia) 2027: The Complete Guide to Wales’s Mountain National Park
Eryri National Park covers 823 square miles of northwest Wales, making it Wales’s largest and highest national park. It is home to Yr Wyddfa (Snowdon, 1,085m), the highest mountain in Wales and England, alongside a landscape of glacial lakes, ancient oak woodland and dramatic ridgelines that draws nearly four million visitors every year.
In 2022 the National Park Authority officially adopted the native Welsh names for the park (Eryri) and its highest peak (Yr Wyddfa), cementing the region’s cultural heritage; both names are now used exclusively on official signage and by local businesses.
This guide covers the best things to do in Eryri in 2027, from climbing Yr Wyddfa to kayaking the calm waters of Llyn Padarn, with practical, checked details on hiking routes, parking, local operators and what each experience actually involves.
Climbing and Walking in Eryri
Eryri has more named walking routes than any other national park in Wales. Yr Wyddfa (Snowdon) has six established ascent routes. The Glyderau and Carneddau ranges to the north offer serious ridge walking with far fewer people. Our hiking in Wales guide covers routes across the park in detail.
Yr Wyddfa (Snowdon) — Pyg Track, Llanberis (LL55 4TY)
The Pyg Track is the best first-time route up Yr Wyddfa, better views than the Llanberis Path, a more interesting ascent over the lip of Cwm Dyli, and about 90 minutes shorter in total walking time. The route starts from the Pen-y-Pass car park (LL55 4TY) at 359m and climbs 726m to the summit in approximately 7 miles return, 4–5 hours for a fit adult at a steady pace. The final section above Bwlch Glas is a clear path on rocky ground, no scrambling required in summer conditions.
Parking and timing
Pen-y-Pass car park (LL55 4TY) has only around 66 spaces and operates pre-book only through the main spring–autumn season (roughly late March to early November, exact dates vary each year). Book via JustPark at least an hour ahead, from £25 for up to 8 hours, £35 for 8–12 hours, £45 for a full day, verify current rates at eryri.gov.wales before travelling. Using the Nant Peris Park & Ride (£5) or the Sherpa’r Wyddfa bus is strongly recommended as it fills weeks in advance; an all-day adult ‘1bws’ ticket costs around £7 for unlimited travel. At the summit, the Hafod Eryri café typically opens for the May–October season, weather permitting.
Guided ascents of Yr Wyddfa are widely available through operators based in Llanberis, such as MountainXperience or Snowdonia Active. A guided walk is recommended for those unfamiliar with mountain navigation, weather on Yr Wyddfa changes rapidly, and the summit plateau requires confident use of a map and compass in poor visibility.
Other routes
The Llanberis Path (from Llanberis village, LL55 4EL) is the longest at 9 miles return, easiest gradient but most crowded. The Miners’ Track (also from Pen-y-Pass) follows the old copper mining railway past three lakes before joining the Pyg Track above Llyn Llydaw. For all six routes with times and difficulty, see How Long Does It Take to Climb Snowdon?
Safety
Yr Wyddfa claims more mountain rescues than any other peak in Wales. Above 800m the weather can change from clear to cloud and heavy rain within 20 minutes. Carry a waterproof layer, warm mid-layer, map (OS Explorer OL17), compass and a charged phone, and check the Mountain Weather Information Service (mwis.org.uk) rather than a valley forecast. In winter conditions (October–April), crampons and an ice axe, and the experience to use them, are required above the zig-zags and the Bwlch Glas intersection.
Tryfan, Ogwen Valley (LL57 3LZ)
Tryfan (918m, officially 917.5m since a 2010 GPS resurvey corrected the long-standing 915m figure) is famous for being the only mountain in Wales and England that cannot be summited without using your hands. The north ridge from the A5 at Ogwen is a continuous Grade 1 scramble with exposed sections. The summit is marked by two standing stones, Adam and Eve, traditionally jumped between despite the drop on both sides. Most experienced hillwalkers complete Tryfan in 4–5 hours return.
Parking and access
Ogwen Valley parking is notoriously difficult. Layby parking on the A5 below the north ridge (LL57 3LZ) fills early on summer weekends. The National Park Authority car park at the Ogwen Centre is card-only Pay & Display, around £6 for the day, and the National Trust no longer offers dedicated parking at Ogwen Cottage. If full, Bethesda Football Club offers parking (around £7) with the Bws Ogwen shuttle to the trails.
Visitor info
Cwm Idwal is a National Nature Reserve from the Ogwen Centre, a 45-minute circular walk to a glacial lake. The Idwal Slabs are one of Wales’s most important rock climbing locations, visible from the lakeside path. Combine Tryfan with the Glyderau ridge (Y Garn and Glyder Fach) for a full mountain day.
Safety
Grade 1 scrambling throughout the north ridge means hands are needed at all times, not suitable without prior scrambling experience or comfort with exposure. Wet rock becomes very slippery. If the north ridge becomes too challenging, descend via the south ridge towards Bwlch Tryfan instead, much less technical.
Eryri’s Towns and Villages
Eryri’s villages are built from grey slate and Welsh stone, compact settlements that served the quarrying industry for 200 years. Llanberis, Betws-y-Coed and Harlech each offer a different experience as a base for the national park.
Llanberis (LL55 4EL)
The main gateway village for Yr Wyddfa, almost every visitor passes through. The village sits between Llyn Padarn and Llyn Peris, below the enormous terraced face of the Dinorwic Slate Quarry.
2027 visitor note
The National Slate Museum, in the former quarry workshops, is still closed for a major £25m redevelopment. The site itself isn’t due to be handed back until September 2027, after which exhibits need several months to return from storage, a spring 2028 reopening is currently pencilled in. Check their website before your trip rather than assuming a 2026 or early-2027 reopening.
Snowdon Mountain Railway
The rack-and-pinion railway runs from Llanberis station (LL55 4EL) to within metres of the summit, the highest railway in Britain. Diesel services to the summit typically run early May to late October, with recent adult return fares around £45 off-peak to £48 peak; the Heritage Steam Experience runs on selected weeks, typically £62 off-peak to £72 peak for an adult summit return. Prices and exact dates are set annually, check snowdonrailway.co.uk before booking, and book well ahead for summer weekends.
Visitor info
Llanberis is busy throughout summer, High Street car parks fill quickly on weekends. Llyn Padarn Country Park, directly behind the village, has lakeside walking and the lake railway within easy reach. The Electric Mountain visitor centre (LL55 4UR) and its underground Dinorwig power station tours are permanently closed, the site is undergoing demolition, so don’t add this to your itinerary.
Betws-y-Coed (LL24 0AJ)
The most popular village in Eryri, a Victorian tourist resort at the confluence of the Conwy and Llugwy rivers, where three waterfalls are within easy walking distance of the car park. Swallow Falls, the most visited waterfall in Wales, is accessible in 10 minutes from the village, entry is approx. £2 via an automated card-only turnstile. Pont-y-Pair bridge over the Llugwy dates from 1475.
Parking and access
The main Cae Llan pay-and-display car park (LL24 0AJ) is in the village centre behind the Conwy Valley Railway Museum, on the A5 between Llangollen and Capel Curig. Transport for Wales runs direct trains on the Conwy Valley Line from Llandudno Junction, a scenic 25–28 minute journey.
Visitor info
Betws-y-Coed is significantly quieter midweek than at weekends, and has a full range of cafés and outdoor equipment shops, the best place in Eryri to stock up on walking gear. The Gwydir Forest above the village has an extensive network of waymarked mountain bike and walking trails, free to enter.
Lakes, Waterfalls and Scenic Drives
Eryri’s glacial lakes and valley waterfalls are among the most visited non-mountain attractions in the national park, accessible to visitors who want exceptional scenery without a full mountain day.
Llyn Gwynant and Nant Gwynant (LL55 4NW)
The A498 through Nant Gwynant is arguably the most scenic road in Eryri, running between Beddgelert and Pen-y-Pass along a glacial valley floor, flanked by Llyn Dinas and Llyn Gwynant with the Yr Wyddfa massif above. Lake access around Llyn Gwynant is popular for paddleboarding and summer swimming, though the water is famously cold. The Watkin Path up to Yr Wyddfa begins nearby at Pont Bethania.
Parking and access
Options include the Llyn Gwynant campsite (approx. £5 launch/visitor fee) and the National Park Authority car park at Pont Bethania (LL55 4NR, approx. £6 for a full day). Both fill quickly on summer weekends. The Wyddfa bus serves Nant Gwynant via the Beddgelert–Pen-y-Pass service.
Visitor info
Beddgelert village (LL55 4YD), 3 miles south, is one of the most attractive villages in Eryri. The Gelert’s Grave walk (30 minutes return) follows the Glaslyn riverbank through flat, easy woodland, the best accessible walk in the park for families with young children. The nearby Sygun Copper Mine (approx. adults £11, children £7.50, verify current prices) is a good hour for families.
Pistyll Rhaeadr Waterfall (SY10 0BZ)
At 73 metres, Pistyll Rhaeadr is the highest single-drop waterfall in Wales, officially one of the Seven Wonders of Wales. Technically just outside the Eryri National Park boundary in the Berwyn Mountains, it falls in two stages through a natural arch into a plunge pool. The walk to the base takes a few minutes on a flat path; a steeper zig-zag path climbs to a viewpoint over the top.
Parking and access
The main car park is at Tan-y-Pistyll farmhouse (SY10 0BZ), 6 miles from Llanrhaeadr ym Mochnant. It uses an automated camera system, approx. £5 weekdays and £10 weekends, fines are issued for non-payment. The final 3 miles are a narrow single-track lane, unsuitable for large vehicles or caravans.
Visitor info
Don’t rely on satellite navigation for the final approach, follow the physical road signs from Llanrhaeadr ym Mochnant village, GPS routes often lead down an impassable farm track. The waterfall is most impressive after heavy rain, best visited in autumn or spring when flow is high and crowds have thinned.
Family Activities in Eryri
Eryri has a strong range of family activities beyond mountain walking, zip wires, underground adventures, narrow-gauge railways and flat-water kayaking all operate within the national park.
Zip World, Bethesda (LL57 4YG)
Zip World operates multiple experiences across North Wales. The flagship, Velocity 2 at Penrhyn Quarry, is the fastest zip line in the world, over 1.5km from the quarry rim to the lake floor at speeds exceeding 100mph. Bounce Below, in the caverns at Blaenau Ffestiniog (LL41 3NB), is a network of trampoline nets in a Victorian slate cavern. Zip World Tower and the Fforest Coaster at Betws-y-Coed suit younger children and mixed-ability groups better.
Booking and requirements
All Zip World experiences require advance online booking, walk-up availability is virtually non-existent in summer. Velocity 2 has a minimum age of 10, minimum rider weight 30kg, maximum 130kg. Bounce Below requires participants to be at least 7, able to reach 1.8m high by hand while standing flat, with trainers and clothing covering arms and legs. Allow at least half a day including travel time.
Velocity 2 at Penrhyn Quarry (LL57 4YG) is 4 miles from Bangor on the A5, with free parking on site. For other adrenaline activities including mountain biking and coasteering, see our guide to Adventure Sports in Wales.
Llyn Padarn Kayaking, Llanberis (LL55 4EL)
Llyn Padarn is the premier flat-water kayaking and paddleboarding lake in Eryri, 3km long, surrounded by the old Dinorwic quarry terraces, with clear views to Yr Wyddfa at the southern end. No experience is needed for flat-water paddling, it’s protected from wind on three sides by the valley walls.
Hire and booking
Snowdonia Watersports (LL55 4EL) is the primary lakeside operator, sharing a building with the Lone Tree Cafe. Hiring a single kayak or paddleboard runs around £35 for two hours including paddle, buoyancy aid and wetsuit, verify current rates before visiting. Sessions typically run 9am to 5pm in summer; advance booking isn’t strictly required but early arrival on summer weekends is recommended.
2027 visitor note: the lake railway
Llyn Padarn Country Park (free entry) surrounds the lake with a flat, pushchair-friendly 3-mile lakeside circuit. The adjacent Llanberis Lake Railway has been running a short 15-minute return hop instead of its usual 5-mile journey throughout 2026, due to National Grid cable replacement work under the track. The railway’s own site says the full lakeside journey is expected to recommence in 2027, though the exact date wasn’t confirmed at time of writing, check lake-railway.co.uk before planning around it. For more on water sports across Eryri, see Water Sports in Wales.
Getting to and Around Eryri
Eryri is in northwest Wales, approximately 4 hours from Cardiff by car and 2.5 hours from Manchester. Getting around without a car is possible but requires planning around local bus timetables.
By Car and Parking
The main approach roads are the A5 from Shrewsbury (via Betws-y-Coed) and the A55 North Wales Expressway to Bangor, then south on the A4086 or A4085. From Cardiff, the A470 north through the Brecon Beacons and Mid Wales is the most scenic route, around 4 hours’ driving to Llanberis.
The Llanberis Pass (A4086) gets severely congested on peak summer weekends, add at least 45 minutes to journey estimates between 9am and 6pm in July and August. Pen-y-Pass operates pre-book only through the main season, you can’t simply arrive early to find a space.
Visitor info
Eryri National Park Authority publishes a sustainable travel guide with car park information at eryri.llyw.cymru. Pay-by-phone parking is common, but signal is patchy, download the JustPark app (required for Pen-y-Pass) and PayByPhone app (required for National Trust car parks) before arriving. Cash is no longer accepted at many mountain car parks.
By Train and Bus
Bangor is the nearest mainline station to Eryri. Avanti West Coast runs direct trains from London Euston, around 3 hours 20 minutes on the fastest services. From Bangor, local buses serve Llanberis (30 minutes), Betws-y-Coed (1 hour) and Caernarfon (20 minutes). The Conwy Valley Railway (Llandudno Junction to Blaenau Ffestiniog) is the best scenic rail route into the eastern park, running up the Conwy Valley through Betws-y-Coed.
Sherpa’r Wyddfa Bus
This network links all the main Yr Wyddfa trailheads in summer, Llanberis, Pen-y-Pass, Nant Gwynant and Beddgelert. An all-day unlimited ticket (around £7) and the Sherpa bus to Pen-y-Pass avoids the parking problem entirely, recommended for summer weekend visits.
Trigonos, an 18-acre lakeside retreat estate on Llyn Nantlle Uchaf in the Nantlle Valley, hosts a rotating calendar of yoga, mindfulness and nature-connection retreats looking directly across the water to Yr Wyddfa’s west face. See our complete guide to Wellness Retreats in Wales for this and four other verified programmes.
Trefriw Woollen Mills in the Conwy Valley has been run by the same family since 1859, generating its own hydroelectric power to weave traditional Welsh tapestry cloth. See our complete guide to Welsh Wool Mills & Textile Heritage for this and four other verified working mills.
Harlech Castle, built in just seven years by Master James of St George and site of the longest siege in British history, sits right on Eryri’s coastline with the mountains as its backdrop. See our complete guide to Harlech Castle for current tickets, opening times and visitor tips.
Where to Stay in Eryri
Llanberis is the most practical overnight base for Yr Wyddfa and the western park. Betws-y-Coed serves the eastern side. Both have accommodation from budget hostels to mid-range hotels and self-catering cottages.
Holiday Cottages in Eryri
Self-catering cottages range from traditional mountain farmhouses with direct hillside access to converted stone barns in the valley villages. A cottage base allows early starts on the mountain, flexibility for weather-dependent days, and self-catering after a long day on the hills, useful when many village cafés close early. Properties in Nant Gwynant, Nant Peris and the Ogwen Valley put walkers within 10 minutes of the main trailheads.
Visitor info
Peak summer weeks (late July to mid-August) fill early at the highest prices. Shoulder seasons, May, June, September and October, offer better availability, lower prices and, for mountain walkers, arguably better conditions: quieter paths, more stable weather and the best light for photography. For the full range of properties, see Holiday Cottages in Snowdonia.
From April 2027, Welsh councils that adopt the visitor levy can charge £1.30 per person per night on most accommodation, 75p for campsites and hostels, on top of your room or pitch rate. Gwynedd, which covers most of Eryri, has postponed its own decision while it works through thousands of consultation responses, see the research data further down this page, so check directly with your accommodation for your dates.
Frequently Asked Questions: Eryri (Snowdonia)
What is the difference between Eryri and Snowdonia?
They’re the exact same place. Eryri is the native Welsh name for the national park, and Yr Wyddfa is the Welsh name for the highest mountain (previously known in English as Snowdon). In 2022 the National Park Authority voted to prioritise these Welsh names, and you’ll now see them used exclusively on official signage, maps and by local businesses.
Is Snowdon the highest mountain in Wales?
Yes. Yr Wyddfa stands at 1,085 metres, the highest mountain in both Wales and England. It is not, however, the third highest in the British Isles as is sometimes claimed, Scotland has over 150 higher peaks, led by Ben Nevis at 1,345m. The Hafod Eryri café and visitor centre marks the summit.
How long does it take to climb Snowdon?
The Pyg Track from Pen-y-Pass takes around 4–5 hours return for a fit adult at a steady pace. The Llanberis Path takes 5–7 hours return, longer but gentler. Times vary with fitness, group size, weather and summit rest time. For all six routes, see How Long Does It Take to Climb Snowdon?
What is Eryri National Park famous for?
Yr Wyddfa, the highest peak in Wales and England, and an extraordinary concentration of glacial mountain scenery across 823 square miles. The park is also known for its historic narrow-gauge railways, including the Snowdon Mountain Railway and the Ffestiniog Railway, its UNESCO-listed slate quarrying heritage, the Italianate village of Portmeirion, and Zip World’s zip lines.
When is the best time to visit Snowdonia?
May and June combine long daylight hours, good walking conditions and lower visitor numbers before the school holidays. September and October are also excellent, with stable autumn weather, great light and quieter paths. July and August are busiest, the Llanberis Pass gets severely congested on weekends, and trailheads like the pre-book-only Pen-y-Pass sell out weeks ahead.
