Snowdonia National Park in North Wales covers 2,130 km² and contains 15 peaks above 900 metres, including Yr Wyddfa (Snowdon) at 1,085 m — the highest mountain in England and Wales. With over 2,000 km of marked trails, Grade 1 scrambles on knife-edge ridges and a network of mountain huts and bunkhouses, it is one of the most varied and accessible mountain environments in northern Europe.
What Are the Best Day Hikes in Snowdonia National Park?
Yr Wyddfa (Snowdon) via the Pyg Track — 8 km return
The Pyg Track is the most scenic of the six main routes to the Snowdon summit and the one most experienced hikers recommend. Starting from the Pen-y-Pass car park at 359 m, it climbs directly to Bwlch y Moch before traversing above the glacial lake of Glaslyn to the summit ridge at 1,085 m. Total ascent: 726 m; typical time: 4–5 hours return. The path is well-maintained and can be busy in July and August — start before 8:00 to beat the crowds and secure car park space before the Pen-y-Pass fills, which it reliably does by 7:30 AM in peak season.
Glyderau Ridge Horseshoe — 14 km circular
The Glyderau horseshoe above the Ogwen Valley is one of the finest ridge walks in Wales. The circuit takes in Tryfan's north ridge (one of the few British mountains requiring hands to reach the summit), Glyder Fach at 994 m and Glyder Fawr at 999 m, before descending via the Devil's Kitchen back to Llyn Ogwen. Budget 6–8 hours. This is a genuine mountain day — navigation competence and scrambling confidence are required.
Cadair Idris via the Fox's Path — 11 km return
Cadair Idris sits in the southern section of the park, well away from the Snowdon crowds. The Fox's Path ascent via the corrie lake of Llyn y Gadair is direct and dramatic — loose scree in the upper section requires care but no technical skill. Summit elevation: 893 m. The mountain's reputation for cloud and sudden weather changes is entirely deserved; carry full waterproofs regardless of the valley forecast.
What Is the Best Scramble in Snowdonia?
Crib Goch — the knife-edge ridge on the northeast spur of Snowdon — is the most famous Grade 1 scramble in Wales. The route involves exposed moves along a 60 cm wide rock arête with drops of 300 m on both sides. In dry conditions, confident hill-walkers can tackle it without technical equipment; in wet or icy conditions it demands rope and helmet. The full Snowdon Horseshoe circuit — Pen-y-Pass, Crib Goch, Yr Wyddfa, Y Lliwedd and back — is the classic route, covering 12 km with 1,000 m of ascent and 6–8 hours for most parties. Descend via the Pyg Track to avoid reversing the exposed ridge.
When Is the Best Time to Hike in Snowdonia?
The clearest summit days occur between late September and early November — after school holiday crowds clear but before the short daylight and ice of winter arrive. May and June offer the longest days (up to 16 hours) and the best ridge-walking light. July and August are busy: Snowdon summit can see 500+ people per day, and the main car parks fill before 8:00 AM. Winter Snowdonia (December–March) is serious mountain terrain — crampons and ice axes are routinely required above 700 m, and several routes close due to avalanche risk. Check the Mountain Weather Information Service (MWIS) forecast before any winter summit attempt.
What Kit Do You Need to Hike in Snowdonia?
Waterproof footwear is mandatory, not optional. Annual rainfall in the Snowdonia massif averages 3,000–4,000 mm — among the highest in the UK — and paths on popular routes hold standing water even in August. The Keen Targhee III Mid WP offers full waterproofing, excellent grip on wet rock and the ankle support that matters on technical descents. For a complete comparison including trail runners and stiffer mountaineering options, see our 2026 hiking boots guide.
Layering is critical in Snowdonia, where temperature can drop 8–10°C between valley floor and summit ridge. A merino base layer like the Icebreaker 200 Oasis Crew manages moisture without clammy synthetic feel — essential when you're working hard on ascent and then exposed and stationary on a cold ridge. Our complete layering system guide covers how to combine base, mid and shell layers for variable mountain weather.
For technical terrain and long descents, trekking poles reduce knee load significantly. The Leki Cressida Carbon poles (460 g per pair) fold compact, have secure wrist straps and handle Snowdonia's mix of rocky paths and grassy ridges well. See our 2026 trekking poles comparison for the full field of options. Finally, never hike Snowdonia without a map and compass or GPS — the Snowdonia National Park Authority publishes current trail conditions and closures updated weekly, and more mountain rescues happen here than in any other UK national park.

Frequently Asked Questions
Do you need a guide to hike Snowdon?
No guide is required for the main Snowdon routes (Pyg Track, Llanberis Path, Miners' Track) in good summer conditions. For Grade 1 scrambles like Crib Goch, first-timers strongly benefit from going with an experienced partner or a guided group, particularly when the ridge is wet or when other inexperienced parties create bottlenecks on narrow sections.
Can you hike Snowdon in winter?
Yes, but winter Snowdon is a serious mountain undertaking. From December to March, ice and snow are common on all routes above 700 m. Crampons and an ice axe are frequently required, and several paths become avalanche risk zones. Check the MWIS forecast and Snowdonia NPA conditions page before any winter summit attempt — the majority of Snowdonia mountain rescues occur in winter months.
Is there a fee to hike in Snowdonia National Park?
There is no entrance fee for the national park or any of its trails. Parking fees apply at most trailheads — Pen-y-Pass charges £8–£12 per day and fills before 7:30 AM in peak season. The Sherpa bus service from Llanberis, Bethesda and Nant Peris is an affordable car-free alternative and stops directly at Pen-y-Pass.
What is the best map for hiking in Snowdonia?
Ordnance Survey Explorer OL17 (Snowdon / Yr Wyddfa) covers the northern Snowdonia peaks at 1:25,000 scale. For southern Snowdonia including Cadair Idris, use OL23. Digital apps with OS layer access (Komoot, ViewRanger) are a practical supplement but should never be your only navigation tool in mountainous terrain.
