We've got two nights in Reyjavik, and two nights in the Golden Circle. We're on an escorted tour with Kuoni. I've been keeping an eye on the current weather, and it doesn't seem much colder than the UK at present. Obviously we're taking thick jackets, fleeces, layers and thermals, but will jeans be ok for day time, or would something like salopettes be better, or even walking trousers with thermal leggings underneath? I'm also taking one pair of snow boots and one pair of walking boots.
Any helpful hints?
