One of two routes starting from Pen y Pass, the Pyg Track is a rocky and difficult path with several steep climbs.
While the Pyg track is one of the shortest routes up yr Wyddfa (Snowdon), it is the most rugged and challenging route to the summit.
Beginning at Pen y Pass, the Pyg winds its way up to Bwlch y Moch, where you will catch your first glimpse of Llyn Llydaw and its iconic causeway. The Pyg continues until it eventually meets the Miners’ Track up towards Llanberis Path and onwards to the summit.

The name ‘Pyg’
It is unclear why this path is called the Pyg Track, but there are plenty of plausible explanations. One possibility is that it was named after the pass it leads through, Bwlch y Moch (Pigs’ Pass)—Pyg is sometimes spelt as ‘Pig Track’. Another possibility is that its name is derived from the fact that miners used the path to carry ‘pyg’ (black tar) to the copper mines on Yr Wyddfa (Snowdon).
At the southern foot of Snowdon is the Pen y Gwryd Hotel which could also be the inspiration behind this path’s name. The team who conquered Everest in 1953 stayed in this hotel while training on Yr Wyddfa (Snowdon). Upon their return from the Himalayas, they held a reunion at the hotel, accompanied by Edmund Hillary.
Llyn Llydaw causeway
As you ascend the Pyg Track, you will likely see the causeway across Llyn Llydaw. The Miners’ track crosses this causeway. Before being built in 1853, miners of the Britannia Copper Mine used a raft to carry horses and wagons full of copper across the lake. The building work unveiled a prehistoric oak dug-out canoe, measuring 10ft by 2ft providing evidence that man has roamed this mountain for thousands of years.
Bwlch y Saethau (Pass of the Arrows)
Looking across Llyn Glaslyn, to the left of the summit of yr Wyddfa (Snowdon), you will see Bwlch y Saethau (Pass of the Arrows). Miners from Beddgelert used to climb over this pass with the help of iron chains fixed to the rock.
Legend has it that this is where an arrow struck King Arthur in battle. He was then carried to the shore of Llyn Llydaw, where a boat with three maidens came to take him away through the mist to Afallon (Avalon).
