Situated in the heart of the central Quang Binh
province, Son Doong (Mountain River) Cave –
the world’s largest cave – was first discovered in
1991 by a local hunter seeking shelter from the
rain. At over 200 metres across, 150 metres
tall and 6,500 metres long, this cave was
formed from an underground river cutting
through layers of limestone along a geological
fault. It’s so big, it’s yet to be fully explored.
First opened to the public in 2013, this
three-million-year-old cave has its own
weather and ecosystem, including jungles,
clouds of mist, ancient lakes, and waterfalls. Its
treasures include rare cave pearls, passages lined
with ancient fossils, and the world’s
largest stalagmite. Permits are granted under
only one company, Oxalis Adventure Tours,

and all visitors must be accompanied on the
five-day journey into the cave, which includes
abseiling, trekking, and swimming though
underground rivers.
Before the trip, fortify yourself with some
bò lúc lắc, or “shaking beef ” – meat vigorously
stir-fried with bell peppers, onions, garlic and
a savoury, slightly spicy sauce. Found on most
menus, this celebratory dish is either served
with rice or over a bed of tomatoes, pickled
onions, and watercress.
