This superbly situated hostel has three of Snowdon's trails at its doorstep. It has a well-equipped kitchen, laundry and drying room; Mallory's Cafe/Bar (named for a past patron who perished on Everest); and quiet, comfortable rooms, 16 of which are en suite. It's 5.5 miles up the A4086 from Llanberis, and the Snowdon Sherpa bus stops right over the road.
