Son Doong Cave is known as the world’s largest natural cave, housing many limestone grottoes, stalactites and stalagmites. Set within Phong Nha-Ke Bang National Park (about 500km south of Hanoi), the cave is a must visit for adventurous travellers looking to explore one of Vietnam’s natural gems during their holiday.
Son Doong cave was first discovered in 1991 by a local named Ho Khanh, followed by a team of British cavers lead by Howard Limbert in 2009. With sections reaching up to 200 metres high, Son Doong Cave also spans 9 km in length, making it about two times bigger than Malaysia’s Deer Cave. The cave is also home to a variety of wildlife, including monkeys, bats and flying foxes.
