The Lava Tunnel Adventure Tour is a 3–4 Hour Guided Caving Experience | Small Groups | For Adventurous Souls Only
Go Deeper Into Iceland’s Lava Tunnels
Step into the shadows of Iceland’s volcanic past and venture deep inside Raufarhólshellir, one of the country’s largest and most captivating lava tunnels. The Lava Falls Adventure Tour takes you far beyond the standard route — all the way to the end of the cave, where few visitors have gone and where the awe-inspiring lava falls mark the dramatic origin of this geological wonder.
