The most popular day trip from Reykjavik is the Golden Circle Tour which takes you to the most famous sights in Iceland.
The main reason for our visit to Iceland was to chase the northern lights, the Aurora Borealis. This is never a certainty. Firstly when you book you are told the tour will be cancelled if the sky is not clear then there is no guarantee that you will see anything. Most of the tours do at least offer you another trip for free if you don’t see anything.
Reykjavik in February is beyond cold. With a thermal vest two jumpers and a ski jacket I still wasn’t warm. It was dark, windy and about minus 7 but it was amazing!
