Thanks to the Ordnance Survey maps, walking your way all over the United Kingdom is pretty easy. These maps are so intricately detailed that they manage to capture every last church with a steeple as well as every pub in even the most far flung reaches of Great Britain.
After walking around Wales (shout out to Sugar Loaf Mountain!), we were in our cottage one night and turned on the telly to find a program on about the Centre For Alternative Technology. The next day we hopped in our Ford Festiva and made our way there, not realizing how tiny many of the roads we'd need to take were and how much that would add to the total trip.
Three hours into a trip we thought would take half that, we arrived at the Centre For Alternative Technology (CAT) which is built on a former slate quarry. True to their mission, "CAT aims to 'inspire, inform, and enable' people to live more sustainably" through education on and demonstration of solar, wind and hydro power as well as organic agriculture and even alternative sewage systems through compost toilets! There's lots to see and do here for kids and adults alike, from swinging on the eco adventure playground to guided tours with knowledgeable environmentalists.
Don't miss the gift shop which has an impressive selection of green books (purported to be the largest of its kind in the UK) and even unique accessories like the Celtic knot ring I picked up here.
