View of Llyn Padarn from Pont Pen-y-Llyn

Highlight • Viewpoint

On a clear day, from this end of Llyn Padarn you’ll get an enticing view of Snowdon and other peaks.
Its absolutely stunning and well worth the ride.

The obvious slice in the slate is like a gateway to the past! Impressive towers of vertical slate walls which demonstrate the direction of the slate vein that makes this area such a popular sport climbing venue

Important Notice*

2022 Destination Clogwyn Station

The destination for the 2022 season is Clogwyn Station which is the 3/4 point on the mountain. The journey time to Clogwyn is approximately 45 minutes and passengers have a 30 minute stop-over at this unsheltered station. The round trip to Clogwyn and back is approximately 2 hours in total, which includes the 30 minute stop-over. Please be aware that there are no facilities at Clogwyn, or on-board the trains.

The summit building, Hafod Eryri, will remain closed for the 2022 season, as there will be no access for service trains or staff, as a result of essential upper mountain track work and will open as normal for 2023. We apologise to any customers who wished to travel to the summit but hope they can still appreciate the fantastic and unique journey up to Clogwyn.

Please note: only registered support dogs are allowed on our trains.

Llanberis Village and Llyn Padarn

Highlight • Settlement

Llanberis is synonymous with Yr Wyddfa (Snowdon). It's a popular starting point for some of the easier ways to the roof of Wales. Whether it’s via the Llanberis Path or a ride on the Snowdon Mountain Railway, thousands of people every year head to the village with the summit in their sights.

Long before it was a draw to tourists and hikers, Llanberis was a slate mining town. The Dinorwig Quarry's slate tips are a stark reminder of the region’s heritage.

The village is blessed with several good outdoor gear shops and characterful places to eat and drink.

Llanberis Lake Railway

Highlight • Structure

Not been on this myself but on a conversation with a member of the public I'm told it's a wonderful journey around to the north side of the lake away from the hustle and bustle of the South side

Llyn Padarn

Highlight • Natural

Llyn Padarn is a glacial lake that's about 3.2km long. The lake side trail makes a great flat run which is a nice change from running around the mountains of Snowdonia. The slate quarries and mountains provide amazing views and there is even a little train that travels along the northern shore that could transport friends while you run or provide a return.
