Let’s just get this out of the way: You can see the Northern Lights in Iceland, and they’re even more breathtaking than you imagine. Also known as Aurora Borealis, this surreal, other-worldly phenomenon is the result of electrically charged particles from the sun colliding with gaseous particles in the Earth, which produces displays of bright, colorful, dancing lights across the sky. The lights are best seen in the colder months when there’s the least amount of sunlight, so the safest bet is to book a trip between late September and late March. As for the best time of night, aim for 11 p.m. or midnight. Of course, you’ll also want to escape the city lights as much as possible for optimal viewing.
