I am not going to Iceland but have been and it's brilliant,especially bathing in the hot Blue Lagoon while it's cold and rainy in the open. It's a lovely feeling and you will be so re-vitalised after. The land is like walking on a volcano - everywhere you go is volcanic rock, there are some lovely picture takes (especially looking out to the Atlantic Ocean). Make sure you wrap up, I hope you have a lovely time.
