Beyond Selidor

That is all super advice — really, really helpful. It's sounding as if it might be worth spending half the time in Reykjavik (probably the second half so we can be closer to the airport for our return flight), and the other half elsewhere (possibly one night in Höfn, one in Vik, and one in a waterfally place).

Thanks once again for your offer of maps, guidebooks, and your own knowledge. I'll definitely take you up on that, and will certainly have time to stay for a cup of tea and a bit of brainstorming. As soon as Alison's sent out her bread email, I'll email you and sort out which night I'll be dropping by.

Thanks also for the warnings about food and weather. My mum and I have hiked in Norway (around Bergen), so we are familiar with changeable Nordic weather, and expensive Nordic prices, even if those in Iceland are a little bit more extreme than their Norwegian equivalents. We'll make sure we're well prepared in terms of warm clothes, and braced for expensive meals.
