The Tu Lan Cave System, which includes more than 10 caves in the province of Quang Binh, has seen an enormous increase in popularity since it was featured in the 2017 movie "Kong: Skull Island."
According to Limbert, "a lot of people visit because of the movie, but they discover that the scenery is even more magnificent than they anticipated."
"Since every campsite is next to a lake or a waterfall, swimming in the warm weather is a breeze. On one of our Tu Lan tours, you enter one tunnel, exit into another area of the jungle, and then enter another cave again."
In order to maintain the area pure, Oxalis offers flexible one- to four-day tours across the area.
"We keep everything very under control here, and you hardly ever see other people. You'll be alone in a cave, "Limbert explains.
The two-day journey through Hang Tien, one of Tu Lan's most well-liked excursions, is named after stunning rock formations that resemble terraced rice paddies and enchanted swirling patterns that appear on the limestone walls.
The journey leads visitors through two tunnels before entering the vast, dry caves, which are a combined 5.5 kilometers long and 100 meters tall at its highest point.
According to Limbert, "These caves are drier than many of the other caves in the vicinity, therefore they usually attract tourists who don't want to swim on the trip." You will never feel claustrophobic in these two caverns since they are so enormous.
