On this tour we take you to the famous Hengill Volcano and into the Icelandic underground!

The journey begins by exploring 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 the beauty of stalagmites and stalactites.

Having enjoyed the hidden beauties of the underground, we head out to the Hengill geothermal area where an easy hike in magnificently ethereal surroundings, dotted with hot springs and bubbling mud pools, awaits you. The hike continues down through Reykjadalur, the Smokey Valley, where it is possible to enjoy a natural bath in a warm stream.
