The Northen Lights
September and April is the best time to catch it
When thinking of Iceland you automatically think of the Northern lights.
Those tours normally start around 10pm and can stay until 2am. It is hard to promise you will see the northern lights but the period between September and April is the best time to catch it. Note that they are only visible under certain condition it has to be a solar activity.
The guide will take you where ever there is the best chance to see the Northern lights so often we say we are going for a Northern lights hunting.
