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.

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.
