It sits at 6,890 feet above sea level and inside the Eiskogel mountain. There's a good walk up to the cave which can take up to 12 hours there and back.

The heritage site

Where: Slovakia
What: A UNESCO World Heritage Site
Must-visit rating: 6 — Nice ice, but there's a walkway

The Dobšinská Ice Cave may not be the biggest or the longest, but it is a UNESCO World Heritage site and has been since 2000. The majority of the cave is covered in ice, and that’s what makes it so important. It was also the first cave in Europe to be lit electronically.

The cave to climb

Where: Canada
What: A booming ice chasm
Must-visit rating: 10 — If you can ice-climb

This is one of the more dangerous caves to explore — crampons are a must, as is knowledge of ice climbing. There’s a vast ice sheet in the cave, but one slip could send climbers plummeting down to the bottom. There’s also a big echo in the cave, making communication quite difficult.

Must-visit rating: 8 — Pretty spectacular
