My friend and I are in Reykjavik from Feb 19th-24th and would love, love, love to see the northern lights. I understand it is weather dependent, but could anyone recommend a company who do nice laid back small group tours? I'm not keen on being shuttled in a coach to 1 location, and am more interested in a smaller group who are willing to go to a different location if necessary. I would normally take a back packer type tour, but find recommendations are always helpful. thank you!
