#1 - Mount Snowdon Via Miner's Track

Length: 7.9 mi • Est. 4 h 58 m
The Miners’ Track to Llyn Glaslyn was built during the last century to serve the Britannia Copper Mines. Abandoned in 1917. The track to the lake is still almost a road, and though eroded in some places, nevertheless provides an exciting mountain walk for people with little experience of mountains. The path beyond Llyn Glaslyn to the summit is considerably steeper and can be a serious undertaking.Show more

Views will range from nothing to breathtaking depending on weather. And the earlier, the better - avoid the crowds especially at Penypass Car Park (gets full quickly) and the summit (will have to queue when train start running) A great route to Snowdon.Show more

Views are amazing, but the climbing scramble up and along the ridge are not for the faint. Wouldn’t try the ridge section on a gusty or rainy day unless you’re an experienced climber.Show more

Snowdon is one of the most popular walks in the UK. With incredible views, challenge, and intricate routes, it is truly awe-inspiring. There are many different ways to get to the summit, but this route combines some of the best. This route starts at the parking area off A4086. You'll go southwest on the Pyg Track eventually traversing Crib Goch. You'll have excellent views of Llyn Llydaw to your left. This is a "razor ridge" section, with steep drops to either side. This section requires a lot of rock scrambling. It is not terribly difficult, there are plenty of handholds, but there are steep drop-offs to either side and it will require a good degree of physical fitness. You'll eventually reach Crib y Ddysgl, which is the second highest peak in Wales, behind Snowdon. Then the final scramble up to Snowdon. From here there should be amazing views. This is a good place to take lunch. After enjoying the Snowdon summit, you'll continue south along the Watkin Path traversing the Bwlch Main. You'll then reach the Y Lliwedd Route, which is another stretch of complicated scrambling. Make sure to get low, use your hands, and be careful. After the Y Lliwedd Route, the path will finally level out and you can take the Miner's Trail back to the car park. Although dogs are allowed in this area, it is certainly not advisable to bring them because of the scrambling.Show more

The Nantlle Ridge is a relatively small range in the Snowdonia National Park. As beautiful as this area is, it is not as popular as other parts of the park. This range can be accessed from the other side too, but entering from the Rhyd Ddu side is the most popular. This route requires some scrambling so be prepared. Gloves come in handy along with a moderate level of physical fitness. The first summit you come to is Y Garn, then Mynydd Drws-Y-Coed, Trum Y Ddysgl, then Mynydd Tal-y-Mignedd.Show more

Fantastic walk. Very accessible with views to reward your effort. Weather permitting it's arguably the best view of Snowdon you’ll get.Show more

Although this is not the most popular route up Snowdon, it is just as awe-inspiring and brilliant. The start of this path is easy to find and level. After a couple kilometers, you'll reach the mountain scenery and the first section of stone steps. Around this area there will be some light rock scrambling. The first summit you reach is the Bwlch Main summit. Eventually the path becomes flatter, and thins down. After the rocky section this is welcomed. After reaching Snowdon you could either return down the South Ridge Path or return via the Rhyd Ddu Path (shown on the map on this page).Show more

Great walk. Definitely quieter than other routes. It is certainly steep on Rhyd Ddu on the way up but nothing that someone moderately fit couldn't handle. The climb to the summit is a bit narrow and the wind can get pretty biting towards the top. On the way down be careful not to follow the Ranger path all the way, look out for the ladder over the fence to the left and before the gate which is the way down the Ranger path. Show more
