Mountains, Caves and Lava Tubes

Lava tubes are a type of lava cave that form when slow flowing lava cools and solidifies on the tops and sides during an eruption. Once the eruption ceases the lava drains from these ‘channels’ and a new lava tube cave is left behind.

Lava tubes contain many amazing features to discover including mineral stalactites and stalagmites, fascinating lava pillars, and ghostly ice sculptures. Some lava tubes become covered in perennial ice over time and become known as ice caves. There are dozens of caves worth seeking out with a professional guide.
