The cave makes for a majestic sight with crystals growing up to fifteen meters long, though sadly the caves are closed due to the general public due to the intense heat within them and as they’re so far beneath the Earth’s surface.

8. Antelope Canyon, USA
Located in the Arizona desert, Antelope Canyon’s walls are smooth, fluid and lined with a mix of red and orange colors. Over the years they have been carved out during the monsoon season when flash floods stormed the canyon, something which still occurs and changes the shape of the caves yearly.
Many unwary tourists have been fatally caught out during monsoon season by these beautiful, if sometimes deadly caves.
