The Miners and Pyg Tracks up Mount Snowdon are popular walks. The Pyg Track is around 3 /14 miles to the summit, and the Miners 3 3/4 miles.Thanks to Ray Jacob for his excellent advice and route description below.
Both paths are manageable by persons of reasonable fitness provided you prepare properly; food, good boots, water, appropriate clothes etc. One final thing to remember, Snowdon conditions can change literally in seconds, so be prepared for all weathers!
If it's your first time, try and pick a day with a reasonal mountain (not the regional) weather forecast, although there are still no guarantees what to expect. Also, make sure you will have enough daylight to complete the journey, as even for a fit agile climber it's likely to be a good 5 hours - considerably more for a novice walker or family with young children. Just take your time, its' not a race, and when you feel the need to stop and rest then do just that.
When Ray walked it he wondered what all the fuss was about, it was a brilliant day and he questioned why he was carrying so much stuff, but after a light drizzle shortly after the start and sunshine towards the middle section, the cloud suddenly dropped on the final assault and he was hit by almost zero visibility. Very strong winds came out of nowhere, along with freezing rain stinging his face. If you don't need your gear, great, but if you have an experience like Ray you'll be pleased you took it with you! Although the paths are well marked, in mist it is easy to become disoriented, so a map and compass and GPS is still essential.
Both paths start at Pen y Pass Youth Hostel (A4086 Llanberis Pass) but if you want to use the car park (which is expensive!) get there very early. There is a free layby car park another 1.5 miles or so on towards Llanberis but this does add another 3 miles to your walk. Another option is the Sherpa bus which stops at the Youth Hostel. Look on the Sherpa website for information - the Sherpa bus does have the option that you can ascend this route, and descend by another path.
Once at the Pen Y Pass car park the Pyg Track starts by leaving via the top right hand corner of the car park. If you want to take the Miners Path, walk a few metres back towards the south east and a gate marks the start.
The Miners Track is the longer of the two routes but is very gentle from the start and for much of the way. It is a very good well defined path which, after a somewhat boring start, gives some iconic views of Snowdon reflected in Llyn Llydaw (weather permitting). The downside is that it obviously has to ascend to the same height as all the other paths, so no prizes for guessing that the last section is steep and demanding, and the parth not so clearly defined as it requires some clambering over a rocky section.
The Pyg Track ascends in two main sections separated by a welcome flat section with great views from a height firstly down the Llanberis Pass and up to Crib Goch, then Llyn Llydaw, Llyn Glaslyn and eventually the summit. The Miners Track is visible at lake level, and this will later ascend to join these paths. Both paths, after another rather steep section, will join the Llanberis Path to push on to the summit following the railway lines on which the Snowdon Railway carries the lazy people (joke!)
Which path to choose? As they both start and finish at the same place, why not go up one, and come back down the other? Both paths have some unique views, and Ray's suggestion would be to go up the Pyg and come back down the Miners. The reason being is that the descent is quicker using the Miners, and once at lake level, apart from one more minor downward scramble, the remainder of the walk is quite gentle and the path easy to follow. A good thing isf the weather conditions change or the light begins to fail.
