During daylight hours Snowdon is a wonderful challenge. Taking it on in the dark brings a whole new adventure in itself.

Climb to the summit of Snowdon at night to see the sunrise across Snowdonia. Enjoy the start of a brand new day with a Snowdon Sunrise and views across the mountains and coast from Wales’ highest mountain.

Snowdon, or Yr Wyddfa to use its Welsh name, stands at 1085 metres and is the highest mountain in Wales (and England). Its rugged beauty attracts people from all over the world. Views from the summit have been voted the best views in the UK.

Registration is just £15 (+ fees) and we’re asking participants to raise a minimum of £80 to help all those affected by cancer, in Wales and beyond.

The path (although starting with a steep tarmac section which isn’t the best introduction to the mountain) climbs steadily uphill via a rocky path until you reach Hebron gate at 352m after about 1.2 miles (2 km).

The going gets easier here for a while as we climb towards half way house, which many people think is halfway distance to the summit. It is actually just over halfway distance at 2.4 miles (4 km) with 2.1 miles (3.3 km) left to the summit. It is the height which is halfway as it is at 540m.

The path continues to climb steady at first until we arrive at the Allt Moses steps at 3 miles (4.8 km) and 645m in height.

For the next 0.3 miles (0.5 km) the path climbs steeply on steps and rocky paths as we quickly gain 135m in height before arriving at Clogwyn station bridge.

Clogwyn Bridge is at 3.4 miles (5.4 km) and 780m in height and once through under the bridge we have fantastic views down into Cwm Hetiau, Nant Peris and across to the Glyderau mountain range.

Continuing above Clogwyn bridge we ascend steeply via a difficult scree slope towards Bwlch Glas. Here you will see the junction of paths (Ranger path, Crib Goch and Pyg Track) that come together for the final few hundred metres to the summit.

Take a moment to view the spectacular ridge of Crib Goch (red ridge) and down into the Cwm that holds Llyn Glaslyn and Llyn Llydaw reservoir.

From here it is just under 0.4 miles (0.6km) to the summit of Snowdon (Yr Wyddfa), the highest mountain in Wales at 1085m!


On the way back down it offers fantastic views towards Llanberis and the Dinorwig slate quarries. In the distance Elidir Fawr and to the west Moel Elio, Moel Cynghorion, Foel Goch and Foel Gron.

On a clear day you can see across the mountains and over the Menai straights towards Anglesey.

(For our descent we simply reverse the route back to Llanberis)
