Journey Into Iceland’s Volcanic Underground
Discover the hidden world beneath Iceland’s volcanic landscape with our fascinating lava tunnel adventure. Walk through natural tunnels carved by flowing lava, exploring colorful mineral formations and learning about the powerful geological processes that created these underground wonders.
What You’ll Discover Underground
Lava tubes form when the surface of a lava flow cools and solidifies while molten lava continues flowing beneath, creating natural tunnels through volcanic rock. Inside, you’ll find evidence of ancient lava flows frozen in time — flow patterns, cooling textures, and vibrant mineral deposits created by volcanic gases, including sulfur, oxidized metals, and crystalline formations unique to these environments.
A Geological Journey for All Ages
Expert guides lead you safely through chambers and passages of varying heights, explaining volcanic geology and pointing out features from smooth pahoehoe lava to rougher formations. The easy walking conditions and family-friendly approach make this a perfect introduction to underground exploration, accessible to visitors of all ages (minimum 3 years) and fitness levels.
We offer two tours that include a visit to the Lava Tunnel:
