Hiking in Wales 2026: Complete Guide to Mountain Trails, National Trails and Summit Routes

Wales has five national trails, three national parks, 15 peaks over 900 metres and over 1,700 miles of public footpath in Eryri alone.

This guide covers the full range of hiking in Wales — from multi-day national trail planning to one-day summit routes, ridge walks, gorge walks and guided hiking options — with specific trailheads, distances and ascent figures throughout.

Yr Wyddfa (Snowdon): Routes, Times and Planning

Yr Wyddfa (Snowdon) at 1,085 metres is the highest mountain in Wales and England. Six main walking routes reach the summit — ranging from 5 to 9 miles return. All are waymarked.

The Llanberis Path (9 miles return, 945m ascent) starts from the Pen-y-Pass car park (LL55 4NY) and is the longest route but most straightforward navigation. Allow 5–7 hours return. The car park fills by 7am on summer weekends — use the bus service from Llanberis or Caernarfon instead.

The Pyg Track (7 miles return, 730m ascent) starts from Pen-y-Pass (LL55 4NY) and is the most popular route — good path throughout, spectacular views from the zigzags on the final approach. Allow 4–6 hours return.

The Miners’ Track (8.5 miles return, 730m ascent) also starts from Pen-y-Pass — gentler gradient for the first 3 miles along the shore of Llyn Llydaw before joining the Pyg Track for the final ascent. Good choice for first-timers.

The Rhyd Ddu Path (8 miles return, 800m ascent) from the Rhyd Ddu car park (LL54 6TN) on the western side is the least busy of the main routes — rarely crowded even in August. Involves some scrambling on the south ridge.

The Snowdon Ranger Path (8 miles return, 900m ascent) from the Snowdon Ranger car park (LL54 7YS) is the oldest named route on the mountain — good condition throughout with fine views over Llyn Cwellyn.

Bannau Brycheiniog (Brecon Beacons): Peaks and Ridge Walks

Bannau Brycheiniog National Park contains four separate upland ranges — the Central Beacons, Black Mountains, Fforest Fawr and Black Mountain — each with a different character and access points.

Pen y Fan (886m) is the highest point — the summit ridge from the Pont ar Daf car park (LD3 8NL) is 4 miles return with 540m ascent. The ridge is broad and grassy — excellent visibility. The car park fills early on summer weekends; arrive before 8am or park in Brecon and cycle to the trailhead.

The Horseshoe Ridge — taking in Pen y Fan, Corn Du (873m) and Cribyn (795m) — is the finest ridge walk in the Beacons. Start from the Cwm Gwdi car park (LD3 8LG) for a circular route of 8 miles and 900m ascent. The north face drops steeply — keep to the path in poor visibility.

The Black Mountains in the east offer longer, lonelier walking. The ridge from Hay Bluff (HR3 5RY) to Waun Fach (811m) is 12 miles return on open moorland — navigation skills required in poor weather. The Offa’s Dyke Path runs along the ridge’s eastern edge.

The Four Waterfalls Walk near Pontneddfechan (SA11 5NR) links four major waterfalls through ancient oak gorge — 6 miles, 300m ascent. Sgwd yr Eira allows walkers to pass behind the falls. One of the finest low-level walking routes in South Wales. See the Brecon Beacons guide for full detail.

Eryri’s Other Mountains: Beyond Yr Wyddfa

Eryri National Park contains 15 peaks over 900 metres. Most receive a fraction of the traffic on Yr Wyddfa — offering comparable mountain experience in genuine solitude.

The Glyderau range — Glyder Fawr (999m) and Glyder Fach (994m) — sits directly north of Yr Wyddfa. The circuit from Pen-y-Pass (LL55 4NY) via the Devil’s Kitchen and back by the ridge is 7 miles with 900m ascent. The terrain on the Glyders is rockier and more scramble-like than Yr Wyddfa — suits experienced hill walkers.

The Carneddau — Wales’s largest high-level plateau — has five peaks over 900m in a connected ridge. The circuit from Ogwen (LL57 3LZ) over Pen yr Ole Wen (978m) to Carnedd Llewelyn (1,064m) is 10 miles with 1,100m ascent. A serious mountain day — carry map, compass and full mountain kit.

Cadair Idris – (893m) — in the south of Eryri, above Dolgellau — is the best mountain in Wales for a first mountain experience after Yr Wyddfa. The Minffordd Path (SY20 9AB) is 5.5 miles return with 830m ascent — a technically straightforward route with dramatic views over the Mawddach estuary.

National Trails in Wales: Long-Distance Hiking Routes

Wales has five national trails — all are waymarked, have published guidebooks and offer accommodation along or near the route.

Pembrokeshire Coast Path (186 miles): from Amroth in the south to St Dogmaels in the north — 10–15 days for the full route. The most dramatic coastal scenery in Wales. See the Pembrokeshire Coast Path planning guide for full detail.

Offa’s Dyke Path (177 miles): from Prestatyn (LL19 9LG) on the North Wales coast to Chepstow (NP16 5EY) on the Severn — 12–16 days. Follows the line of the 8th-century earthwork built by King Offa of Mercia to mark the border with Wales. The central section through the Black Mountains is the most remote.

Glyndŵr’s Way (135 miles): from Knighton (LD7 1EN) to Welshpool (SY21 7DQ) through the heart of Powys — 9–12 days. One of Britain’s loneliest national trails — accommodation sparse and must be booked well ahead. Named after Owain Glyndŵr, the last Welsh prince to hold Parliament.

Beacons Way (100 miles): from Abergavenny (NP7 5HH) to Llandeilo (SA19 6AF) across the full width of Bannau Brycheiniog — 7–10 days. A high-level route crossing all four ranges of the national park. Requires navigation skills on the open moorland sections.

Wales Coast Path (870 miles): the complete coastline of Wales in a single continuous path — the only trail to circumnavigate an entire country’s coast. Sections walkable as day or weekend routes throughout all four regions.

Guided Hiking in Wales: Operators and Organised Walks

Guided hiking is available across Wales — from single summit days to multi-day supported trips with luggage transfer.

Summit guides for Yr Wyddfa are available through several Llanberis-based operators — Mountain Guides Snowdonia and other registered members of the Association of Mountaineering Instructors (AMI). A guide provides route-finding, safety management and cultural context.

Supported national trail walking — with luggage transferred between overnight stops — is available for the Pembrokeshire Coast Path and Offa’s Dyke Path. This allows walkers to complete the trails with a daypack only.

What to Wear and Carry: Hiking Safety in Wales

Wales’s mountain weather changes faster than most visitors expect. Temperature on Yr Wyddfa’s summit averages 5–7°C colder than the valley in all seasons. Wind chill can drop the effective temperature to -10°C in winter — even when it’s mild below.

Essential kit for any Welsh mountain walk: waterproof jacket and trousers, warm insulating layer, sturdy waterproof boots, map and compass (phone GPS fails in cloud and when battery drains in cold), water (1 litre minimum), food, first aid kit and a charged phone.

Check the Mountain Weather Information Service (mwis.org.uk) before any mountain walk in Wales — it gives a 24-hour forecast specifically for Welsh summits, not the valley conditions shown on general weather apps.

Never attempt Yr Wyddfa, the Carneddau or Cadair Idris in trainers or without waterproofs. Rescue team callouts on Yr Wyddfa involve inadequate footwear and clothing in the majority of preventable cases.

Frequently Asked Questions: Hiking in Wales

How hard is the hike up Yr Wyddfa (Snowdon)?

The most used routes (Pyg Track, Miners’ Track) are demanding but achievable for any fit adult with appropriate footwear and kit. The Llanberis Path is longer but less steep. Allow 5–7 hours for any route return. The main risks are inadequate clothing and footwear — not technical difficulty.

What is the best hike in Wales?

There is no single answer — it depends on experience and what you’re looking for. Yr Wyddfa via the Pyg Track is the classic. The Horseshoe Ridge in the Brecon Beacons is the finest ridge walk in South Wales. The Carneddau circuit from Ogwen is the finest mountain day in North Wales for experienced walkers. Cadair Idris from Minffordd is the best mountain for a first big summit experience.

What time of year is best for hiking in Wales?

May and June offer the best combination of long daylight hours, settled weather and low crowd numbers. July and August are busier but have the most reliable weather. September is quieter with good conditions on most days. Winter hiking on Welsh mountains requires experience, appropriate kit and a check of the mountain forecast — conditions can be serious from November to March.

Can children hike in Wales?

Yes — Wales has excellent family hiking at all levels. The Waterfalls Walk in the Brecon Beacons suits children aged 5+. Yr Wyddfa is achievable for children aged 8+ on the Miners’ Track with appropriate clothing. The Mawddach Trail near Dolgellau is flat and traffic-free — suitable for all ages. Cadair Idris is better suited to children 10+ given the steep terrain on the upper section.

Do I need a guide to hike Yr Wyddfa?

No — the main routes are waymarked and do not require a guide. A guide is recommended in winter (November–March) when snow and ice can make the paths treacherous, or for inexperienced walkers who want confidence on the mountain. In summer, fit adults with good footwear and a map can complete the main routes without assistance.
