At 1,085 metres (3,560 feet), Snowdon — Yr Wyddfa in Welsh, a name officially co-equal to Snowdon since 2022 — is the highest mountain in Wales and England, and one of the most-climbed summits in the world. Around half a million people make the ascent each year. From Conwy, visible on clear days beyond the Carneddau foothills, it sits about 25 to 30 miles to the west. The full mountain experience — a route up, summit cafe, views that on clear days extend to Ireland and the Lake District, and the return journey — makes an outstanding full day out from the walled town.
The summit visitor centre, Hafod Eryri, opened in 2009, replacing what Prince Charles once called “the highest slum in Wales.” The new building is low and stone-clad, designed to sit almost invisibly in the ridge. Inside: a cafe serving hot food and drinks, toilets, and a small exhibition on Snowdon’s geology, ecology and cultural history. Cloud covers the summit on the majority of days; checking the Mountain Weather Information Service at mwis.org.uk the evening before is not optional.
By car: From Conwy, take the A55 westbound and exit at junction 11 (Llanfairfechan). Follow signs south through the valley to Llanberis — about 25 miles and 35 to 40 minutes. For Pen-y-Pass (starting point for the Pyg and Miners’ Tracks), continue on the A4086 up through the Llanberis Pass: approximately 30 miles from Conwy, around 45 to 50 minutes. The Llanberis Pass itself is one of the great mountain roads in Wales — the drive up through it, with the Crib Goch ridge rising on one side, is a spectacle in its own right before you reach the trailhead.
Without a car: Conwy is particularly well-placed for a car-free Snowdon day. Take the train one stop to Llandudno Junction, then the Conwy Valley Railway south to Betws-y-Coed (about 40 minutes). From Betws-y-Coed, the Snowdon Sherpa bus network connects the village to Pen-y-Pass, Llanberis and the western trailheads. No parking fees, no 7am alarm to beat the car park queues — just a train and a bus to the foot of the mountain. Current Sherpa routes and timetables at snowdon.com.
All six routes require proper walking boots (not trainers), waterproofs and warm layers regardless of the valley weather. Times below are approximate return figures for a fit adult walker; add an hour or more for children or frequent stops.
Pyg Track — 12km return · 720m ascent · 5–6 hrs · From Pen-y-Pass. The most popular route and justifiably so: well-graded, dramatic views of Glaslyn and the vivid Llydaw lake below, with a proper ridge approach to the summit. Rocky in places; trekking poles help on the descent. The final pull to the ridge above Glaslyn is the hardest section — steady rather than fast is the right approach.
Miners’ Track — 14km return · 720m ascent · 5–6 hrs · From Pen-y-Pass. Follows the old copper-mining tramway past three lakes — Llyn Teyrn, Llyn Llydaw and the brilliant Glaslyn at the foot of the summit pyramid. Broader and gentler than the Pyg Track for most of its length, then steeper where the two routes converge. The best first-time Snowdon route; the abandoned mine workings at Glaslyn add an industrial history to the landscape drama.
Llanberis Path — 14km return · 974m ascent · 5–7 hrs · From Llanberis. The longest but most gradual ascent, following the mountain railway line nearly all the way. The most forgiving route for those less comfortable with steep or rocky terrain. The starting point in Llanberis is the most accessible from Conwy by public transport, and the village deserves at least a half-day in itself for the Slate Museum, Dolbadarn Castle and the lakeside.
Rhyd Ddu Path — 14km return · 900m ascent · 5–6 hrs · From Rhyd Ddu. A quiet western approach with superb views of the Nantlle Ridge and Beddgelert Forest that the eastern routes miss entirely. A good choice for a second visit when you want a different side of the mountain. The ridge section near the top can be exposed in strong westerly winds but the path is clear.
Snowdon Ranger Path — 13km return · 900m ascent · 5–6 hrs · From Snowdon Ranger YHA. The oldest named route, used by Victorian mountain guides. Grassy lower slopes past Llyn Cwellyn, quieter than the eastern routes, with views across to the Nantlle hills. Underused and satisfying.
Watkin Path — 14km return · 1,050m ascent · 6–7 hrs · From Nantgwynant. The most dramatic and most demanding route: the highest ascent of any path, with a steep and loose scree gully below the summit that can be serious in wet conditions. Pass the Gladstone Rock — where William Gladstone, aged 83, addressed 2,500 people in 1892 on Welsh home rule. Not recommended for first-timers or in poor weather. Full route maps and current conditions at snowdon.com.
The Snowdon Mountain Railway is the only public rack-and-pinion railway in Britain — an extraordinary Victorian engineering achievement that has been carrying passengers from Llanberis to the summit since 1896. The journey takes about an hour each way on both heritage steam and modern diesel trains, and the views from the carriage improve at every stage. Steam departures are limited in number and very popular. The railway runs from March to November.
Book directly at snowdonrailway.co.uk — in July and August, trains fill weeks in advance. Return fares are around £30–36 for adults. Many walkers buy a one-way ticket: walk up one of the paths and take the train down (or vice versa), combining the best of both. The railway also stops at the Clogwyn intermediate station, providing access to the Llanberis Path mid-mountain — useful if conditions deteriorate.
For experienced walkers: The classic Snowdon Horseshoe combines routes into a circular ridge walk over Crib Goch, Carnedd Ugain and the summit, descending via the Pyg Track. Crib Goch is a knife-edge ridge with genuine exposure and requires confident scrambling; it is not a walking route and should not be attempted without prior experience or in poor visibility. Those comfortable on it rate it among the finest mountain days in Britain. If in doubt, the Pyg Track up and Miners’ Track down is a satisfying circular alternative using the same car park.
For families: The Miners’ Track and Llanberis Path are the most family-friendly routes on foot. Children comfortable with a long walk and accustomed to hills can manage either — pace them on the ascent and keep something in reserve for the descent, where tired legs cause most problems. Footwear matters: trainers on wet rock are dangerous. The mountain railway from Llanberis is the obvious no-walking option for families with young children or those with limited mobility — book well ahead. See our family guide for more ideas in the area.
For a summer Pen-y-Pass start, aim to leave Conwy by 7am. Check mwis.org.uk the evening before — the summit is in cloud on the majority of days, and what looks fine from Conwy can be a complete whiteout at 1,000 metres. Pack waterproofs, an insulating layer, hat and gloves, OS map or downloaded offline map, food for the day, and at least 1.5 litres of water per person. Mobile signal is poor on most of the mountain — download maps before you leave. Wear boots, not trainers. Book the mountain railway at snowdonrailway.co.uk well in advance.
Pen-y-Pass car park fills before 7am on summer weekends and bank holidays — the Snowdon Sherpa bus from Betws-y-Coed is a far better option if you are car-free or arriving after early morning. Routes, timetables and live summit conditions are all at snowdon.com. If you want to stay closer to the mountain for an early start, Llanberis has the best range of accommodation at the trailhead — or search Llanberis accommodation on Booking.com. Otherwise, Conwy itself makes an excellent base: the town is full of character, the accommodation is good, and the 35-minute drive to the mountain is an easy start to a big day.
