Get great value for money with this extremely popular multi-activity day tour from Reykjavík. Lava caving is one of Iceland's special features. This lava tunnel exploration is a relatively mild caving experience and is suitable for everyone in decent physical shape and who is wearing appropriate shoes. You begin your day speeding across the beautiful Icelandic countryside in a purpose-built ATV quad bike. Your destination is the top of a mountain where you can enjoy amazing panoramic views of Reykjavík City and its surrounding mountains. Then after experiencing the heights, dive down under the earth to explore the caves of an ancient lava tunnel. You experienced guides will lead you through the pitch-black underground tunnels formed by past volcanic eruptions. Standing underground inside the Earth is a feeling you will never forget. The darkness is so dense that it would be impossible to see anything without your caving headlight. Fortunately you will be able to see, as the stalactites and natural ice formations of the cave are simply stunning. You will lose all conception of time and forget about the world overhead as you descend into the cave's darkness on this fun expedition.
