Snowdonia, or Eryri as it’s now officially named, packs an extraordinary amount into a relatively compact national park. From the jagged ridges above the Ogwen Valley to the wooded valleys of southern Snowdonia, the variety is remarkable. Every walk here feels distinctly Welsh: the light is different, the rock is different, and the names are unlike anywhere else in Britain.
If you’re new to the area, it’s easy to feel drawn straight to Snowdon. Resist the urge until you’re ready, the summit paths can be crowded and the conditions variable. These routes are a better introduction: quieter, equally beautiful, and genuinely accessible to walkers at the start of their hillwalking journey.
1. Llyn Idwal Circuit: Ogwen Valley
Distance: 4.5km circular | Ascent: 170m | Time: 1.5–2 hrs
Llyn Idwal is one of the finest glacial cirques in Wales, a dark, still lake cradled between the cliffs of the Devil’s Kitchen and the Idwal Slabs, with the Glyderau rising behind. The circuit path is clear and largely level, making this the ideal introduction to the high-mountain landscape of the Ogwen Valley without significant technical challenge.
Start from Ogwen Cottage (A5 roadside car park). The path crosses a footbridge and follows the eastern shore past the famous climbing slabs before looping back via the outflow stream. On a clear day, the reflections of the surrounding crags in the lake are extraordinary.
The area is a National Nature Reserve and famous for its arctic-alpine flora. In spring, purple saxifrage blooms on the rock faces well before anything else is in flower.
Best for: First-timers wanting high-mountain scenery without a serious ascent.
2. Aber Falls (Rhaeadr Fawr): Abergwyngregyn
Distance: 4km circular | Ascent: 120m | Time: 1–1.5 hrs
Aber Falls is the largest waterfall in Snowdonia, a 37-metre drop into a wooded gorge on the northern edge of the national park, with the Carneddau rising behind. The approach path is good quality and wide throughout; it’s one of the most accessible big-scenery walks in North Wales.
Start from the National Trust car park in Abergwyngregyn village. The path follows the river upstream through oak woodland, giving increasingly dramatic views of the waterfall as you approach. There’s a lower falls (Rhaeadr Fach) on the same circuit that’s easily missed by walkers rushing to the main fall.
Best for: Families, those wanting a short but rewarding walk, anyone arriving via the A55 who wants a quick route to spectacular scenery.
3. Moel Famau: Clwydian Range
Distance: 6km circular | Ascent: 320m | Time: 2–2.5 hrs
Technically on the eastern fringe of the Snowdonia region in the Clwydian Range AONB, Moel Famau (554m) makes the list because it’s an excellent first summit for complete beginners. The main ascent from Bwlch Penbarras car park on the B4501 is well-maintained and clear throughout. The summit hosts the ruined Jubilee Tower and gives views west across the Vale of Clwyd to Snowdonia itself.
This is often used as a warm-up walk before tackling more demanding routes, and it’s one of the easiest mountain summits in North Wales to achieve. The ridge walk north towards Moel Dywyll makes for a satisfying extension if time and energy allow.
Best for: Complete beginners, those wanting an achievable summit, walkers based in North East Wales.
4. Watkin Path to Gladstone Rock: Nantgwynant
Distance: 5km out-and-back | Ascent: 270m | Time: 2–2.5 hrs
The full Watkin Path is a serious route to the summit of Snowdon, but the first half, to Gladstone Rock and the ruined quarry buildings, is a superb beginner walk through one of the prettiest valleys in the park. The path climbs through native woodland and past several waterfalls before reaching a dramatic open cwm with views up towards Snowdon’s summit ridge.
Prime Minister Gladstone opened this path in 1892 at the age of 83; the inscribed rock marking the event is still there. Turning around at this point feels like a natural break and spares you the serious upper mountain terrain.
Best for: Walkers who want a taste of Snowdon without summit pressure, dramatic valley scenery.
5. Cwm Idwal and the Gribin Ridge: Ogwen
Distance: 8km circular | Ascent: 450m | Time: 3–3.5 hrs
A step up from the Llyn Idwal circuit, this route adds the Gribin Ridge to the loop, a broad, grassy ridge between the Glyder plateau and the Ogwen valley that gives excellent views for modest technical difficulty. The path is clear and the gradient reasonable.
Starting from Ogwen Cottage, you follow the Llyn Idwal circuit on the outward leg before ascending the Gribin spur. The return passes Llyn Bochlwyd and the spectacular boulder field beneath Y Garn. Not quite a gentle walk, but well within reach of a fit beginner with proper boots and basic navigation awareness.
Best for: Walkers ready to step up from the easiest routes, those who want genuine mountain views without technical scrambling.
6. Precipice Walk: Dolgellau
Distance: 5km circular | Ascent: 170m | Time: 2 hrs
The Precipice Walk above Dolgellau in southern Snowdonia delivers one of the most dramatic viewpoints in Wales from a relatively easy path. The route follows a narrow shelf path cut into the hillside above Llyn Cynwch, with the Mawddach Estuary and Cadair Idris visible to the south and the Rhinog range to the north.
The “precipice” refers to the steep drop to one side rather than any technical difficulty underfoot, the path is solid and well-maintained. A morning visit in autumn, when the tree colours are at their best, is particularly recommended.
Best for: Dramatic views without serious ascent, those visiting the southern part of Snowdonia.
7. Llyn Gwynant Circuit: Nantgwynant
Distance: 7km circular | Ascent: Minimal | Time: 2–2.5 hrs
One of the most beautiful lake circuits in Snowdonia, with Llyn Gwynant reflecting the surrounding peaks of Moel Hebog and the Snowdon massif. The path is largely level and well-maintained, making this a good option for days when the cloud is low and summit walks are unrewarding.
The lake circuit passes through sessile oak woodland and takes in good views down towards Nantgwynant village. The campsite beside the lake (Nantgwynant Campsite) is one of the best-positioned in Wales, worth noting for a return trip.
Best for: Poor visibility days, those who want lake scenery and easy walking.
Essential Tips for Snowdonia
Weather: Snowdonia sits in the path of Atlantic weather systems and is consistently wet. The peaks receive over 3,000mm of rainfall annually. Always carry full waterproofs regardless of the forecast.
Maps: OS Explorer OL17 (Snowdon and Conwy Valley) and OL18 (Harlech, Porthmadog and Bala) cover most routes. The 1:25,000 scale is the standard for hill walking.
Car parks and transport: Car parks at popular trailheads fill fast on sunny weekends. The Sherpa’r Wyddfa bus network provides a viable alternative, plan routes that use public transport to avoid the parking crush.
Litter: Snowdonia is suffering from the impact of visitor numbers. Pack out everything you bring in, including food waste. The Leave No Trace principles are particularly important here.
