You will start the day visiting the underworld, where you can see and understand how volcanoes created Iceland. You will explore an amazing underground lava tube (get ready to crawl when the ceiling gets a bit low!).
Afterward, you will start the Golden Circle route, where you will visit Thingvellir National Park, Gullfoss and Geysir, the "must-see" attractions in Iceland.
With this trip you are combining nature, history and geology, all in one!
