Soon Doong Cave in Vietnam is the largest cave in the world, and next year you will be able to go on a six day tour there for R30,035! The cave is 5.5 miles long, could house a 40-story skyscraper, has a resident river, waterfall and jungle!
Soon Doong Cave was discovered in 1991 and was first explored just four years ago.
If you’re saving your money for something that is not cave exploring, check out this virtual tour, it is truly amazing.
