Thinking about heading up to Snowdonia in March for a few days. We haven't been up that way before and know nothing about Snowdonia and would like to know recommendations for a good location to stay, things to see - we like good hikes/walks and of course, geocaching (so geocache recommendations are much appreciated!) as well as a spot of photography. Hope this isn't too general... ;) Anyone? Thanks... (we cache as Artemisworks ...)
