Birds, flying foxes, rats, snakes, squirrels, and monkeys, have been discovered underground; and seven new species of eyeless, white creatures (think scorpion, spiders, shrimp, and fish) have been found there. You can weave your way through the world’s largest cave system for $3,000.
Is Son Doong worth?
Yes, it is 3000 USD and it books out for a year in two days! I did the Son Doong Cave trip and absolutely loved it! The views are stunning and the trip super professionally done.
