Explore the famous Hengill Volcano and  the Icelandic underground on this day tour. The journey begins by venturing into one of the many lava caves in the Bláfjöll mountain range, just east of Reykjavík. You will find out how lava caves are formed and discover a wealth of geological formations, including stalagmites and stalactites.

After enjoying the hidden beauties of the underground, we head to the Hengill geothermal area. There, you take an easy hike in magnificently ethereal surroundings that feature hot springs and bubbling mud pools that await your exploration. The hike continues down through Reykjadalur, the Smokey Valley, where it is possible to enjoy a natural bath in a warm stream.
