this place looks interesting for a stop when driving from Myvatn to Akureyri
1) is it open on 28 March when we will be driving through the area?
2) if it's not open, is it possible to view it from outside or walk around the grounds?
3) i presume this is the detour i have to take http://goo.gl/maps/AlbCV . Are the detour roads passable and good to use in winter?
