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

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 Pass – Pen-y-Pass Climb

Highlight (Segment) • Climb

Awesome mountain road from Nant Peris in the west to the top of Pen-y-pass in the east. It's a long climb up from Nant Peris or an exciting descent in the other direction. The A4086 follows the Llanberis Pass with historically important rock climbing and bouldering on both sides. Snowdon is to the south and the Glyders to the north.
Café and shop at the car park at the top along with the YHA Pen-y-pass. There is a nice pub in Nant Peris and cafes and shops in Llanberis a bit further down the road,

Pete's Eats Cafe

Highlight • Cafe

Nothing short of an institution, Pete's Eats is the only place to be when rain cancels play Llanberis. Of all the food and drink available on the impressively extensive menu, the pint sized mug of tea is the product the café is synonymous with. It's as much a Snowdonia rite of passage as the traverse of Crib Goch's main ridge.
