0 miles. Explored Caernarfon, mostly the massive, unfinished castle started by Edward 1. It’s really rather impressive and far, far larger than any of the other castles we’ve seen. Restocked our groceries and caught a late afternoon bus to the youth hostel at the Snowdon Ranger trailhead. Weather forecast for tomorrow isn’t great but should be good enough for a peak ascent even if the view’s a bit obscured.
