Son Doong, located in the Phong Nha-Ke Bang National Park, has captured international spotlight since it was opened to tourists in 2013. "It requires two days of intense jungle trekking and river crossings to reach the entrance of Son Doong Cave," the magazine noted. Oxalis Adventure operates the tour, with a four-day-three-night expedition to the cave costing 69.8 million VND (around 3,000 USD). Only 1,000 visitors are allowed to explore the cave a year for environmental reasons, and the tour is available only between January and August. Trekkers accompanied
