You’ve really got two options: to explore the city of Reykjavik or head out into the wide open spaces which give Iceland its unique majesty.
The most popular day trip is The Golden Circle, including the awesomely beautiful Thingvellir, where Iceland’s first inhabitants held parliament and the tectonic plates are gliding apart, the huge Gullfoss Waterfall and the spouting thermal geysers. There are plenty of daily tours, and if you are there between September and April, you could take a Northern Lights tour.
