Aberglaslyn Gorge and Cwm Bychan, Snowdonia

Hard
4.19 mi·
970 ft
This stunning round hike takes in some of Snowdonia’s most stunning scenery, from the placid waters of Llyn Dinas to the spectacular Aberglaslyn Gorge with the turbulent Glaslyn River raging alongside the path....

Moel Siabod

Hard
6.39 mi·
3,075 ft
Falling short of 3000er status by a measly 140ft, Siabod is often less crowded than the headline grabbing giants across the valley. However, make no mistake, old Siabod rewards those who visit him with some fantastic scrambling and possibly the finest view in the whole of Wales....

Cadair Idris, Craig Lwyd and Mynydd Moel

Hard
5.94 mi·
3,031 ft
Perched in the otherwise rolling hills of Central Wales, Cadair Idris is a rocky, craggy anomaly. The mountain is high, wild and remote, making it a connoisseur's peak rather than one on the radar of glory hunters! The route we've drawn here is the Minffordd Path, the shortest but steepest trail up the mountain....

Cnicht - The Welsh Matterhorn

Hard
6.49 mi·
2,216 ft
When viewed from across the coastal plain in the west, Cnicht takes on the appearance of a perfect pyramidal mountain reminiscent of a miniature Matterhorn, though sadly that’s where the comparison with Zermatt’s finest ends....
5

The Round of Marchlyn Mawr

Hard
4.28 mi·
2,055 ft
The Round of Marchlyn Mawr visits Elidir Fawr before encircling the eponymous llyn by way of two unsung peaks on the Glyderau’s unfashionable northern extremity. A short day with huge views, this walk gives a subtle twist to an old favourite....
6

The Southern Carneddau

Hard
8.94 mi·
3,171 ft
Anyone travelling through the Ogwen Valley for the first time would be forgiven for ignoring the huge grassy whalebacks which form the northern wall of this handsome defile. Indeed, with Tryfan’s striking good looks and the rock studded cwms of the Glyderau on display it’s little wonder that the Carneddau are shunned by those hankering after exciting scrambles and memorable days on classic rock routes....

Snowdon's Quiet Side - Cwm Clogwyn Round

Hard
9.32 mi·
3,091 ft
A round of lonely Cwm Clogwyn ascending the superb Rhyd Ddu path followed by a descent of the Ranger gives you the rare opportunity to exercise your more misanthropic tendencies on one of the most popular mountains in Britain....
8

Glyder Fawr and Glyder Fach

Hard
5.31 mi·
2,494 ft
Taking in Wales' 5th highest mountain and one of the best - and best known - ridgelines in the UK, this is one of Snowdonia's most popular hikes, and with good reason....
9

Nantlle Ridge

Hard
5.17 mi·
2,111 ft
Snowdonia’s biggies are crammed into a small corner of the National Park, along with most of the crowds. In contrast the adjacent Nantlle hills feel like a neglected backwater - in a good way....

Tryfan and the Glyderau: Cwm Bochlwyd Loop

Hard
3.94 mi·
3,035 ft
With its architectural rock scenery and endlessly varied ground this lap of Cwm Bochlwyd has to be the best low-grade hands-on route in Wales. The circuit covers all the main highlights of the central Glyderau: a full scrambling traverse of Tryfan via its north and south ridges; the alpine-esque clambering on Bristly Ridge; the high mountain moonscapes of Glyders Fach and Fawr; monumental rock features like The Cantilever and Castell y Gwynt; and the scrambly crest of Y Gribin ridge....
11

Snowdon Horseshoe including Crib Goch

7.28 mi·
3,348 ft
There's no better route of its kind in the British Isles south of the Scottish border. The walk has a compelling logic, following narrow ridge crests encircling the massif's huge eastern cwm and linking its four principal summits - three of which are three thousanders....

The Welsh 3000s

Hard
25.3 mi·
9,410 ft
The route ascends all the peaks over 3000 feet starting with Snowdon (Yr Wydffa) and finishing with Foel Fras in the Carneddau. The traditional way of doing the Welsh 3000s is starting at Snowdon and finishing at Foel Fras....
