A lovely log cabin in the woods near beddgelert, went in December. It's like an MBA style open door. Virtually impossible to locate. Usually I go in winter to bag mountains and do long walks, but this time we just faffed, cut wood and fixed things. Air like champagne and drinking water out of any drippy bit of moss.
