Just had an excellent day's hike from Llanberis over to Ogwen Cottage. I've uploaded the GPX trace on to Ever Trail.
We stayed the night in Llanberis at the very reasonable Dol Peris bunk house. In the evening the Llanberis curry house was too full for use to get in, so we ended up at the Welsh Curry House of the Year 2007. And very nice it was too.
