Surtshellir itself is 1,970 m (6,463 ft) long, and together with Stefánshellir, forms the longest cave structure in Iceland measuring 3,500 m (11,482 ft)!

The innermost part of Surtshellir is called ‘The Ice Cave.’ Here, the ceiling is lower and is filled with pretty ice candles and columns. The roof of the cave currently has five openings where it has previously collapsed.
