    This was a great tour! I went with my husband and 12 year old son. Our guide was absolutely fantastic (VERY funny and knowledgeable), and it was very cool to see the lava tube. Know that the ground is often uneven, and there are stairs - a consideration if mobility is a concern or if you're planning to bring small children.

    We've explored other lava tunnels in the past, but this one was by far the coolest. Lots to explore and the scenery was amazing. We were told of an extreme tour too that went even further into the cave/tunnel, but this was perfect for our two children, ages 8 and 10.

    Informative tour with an informative tour guide. It’s pretty immense a must do tour in Iceland. I mean it’s rare to see a cave that was once occupied by lava and was formed by an erupting volcano all those centuries ago. Very immersive experience and great.
