Katla Ice Cave, located in South Iceland, is one of Iceland's most incredible natural wonders. Located underneath the massive Katla volcano, this ice cave is known for its mesmerising blue ice formations and intricate patterns. Inside the cave, you'll find shimmering ice walls and a really unique atmosphere which feels almost otherworldly.

It's the only ice cave in Iceland which you can visit year-round, although you have to go with a guide. The cave is constantly changing as the ice melts and re-melts, and no two visits will be the same. Exploring Katla Ice Cave will give you a unique chance to witness the raw beauty of Iceland's glaciers up close, and is one of the best things to do in all of Iceland.
