I have been there.
Rather a rugged, out of the way place.
It would be interesting to know what sort of "tour bus" they were using, but then they do have some rather special vehicles in Iceland.
For those who think that they were stumbling about in the dark at 3 a.m. if this was June or July it would have been daylight all night.
Iceland, magic place, I must go back for a quick holiday sometime.
