5.00Awesome! Very cool lava tube with beautiful colors, textures, and skylights! Stunning when the water drops freeze in a pile and the lights shine through them. They look like a bunch of candles. We highly recommend this activity!

5.00Very well organised. You are provided with everything you need (helmet, crampons & walking stick). The lady who was our guide was amazing. She made it very interesting and you could tell how much she loves her job. Full of enthusiasm and made us feel safe and able to ask questions. Would defiantly recommend this trip to anyone visiting Iceland.

5.00My husband and I enjoyed going into the cave. I was concerned about the walk but it was relatively easy. The company provides you with equipment needed to take the quick trekk. The guide was knowledgeable.
