We recommend that you start planning your trip to Iceland well in advance. A year in advance would be ideal, but 6 months should be sufficient. The longer you wait, the higher the chances are that the accommodation or the tour that you want will be fully booked. On some of our Off the Beaten Path Tours, seats are limited and can fill up quickly. So try to book as soon as possible to secure your spot so you can have the best of what Iceland has to offer.
