Officials in Quang Binh Province stopped three men traveling on French and American passports from attempting to access the world's largest cave alone.

The men, aged 29 to 34, were stopped on February 25 in an ethnic minority village in Phong Nha Ke Bang National Park.
The group reportedly admitted that they were using navigation devices to attempt to unlawfully access Hang En Cave and Son Dong Cave.
Officials from the National Park Management Board described their attempt as potentially deadly.
“Traveling into Son Doong Cave without protective equipment or proper guidance is very dangerous and might lead to life-threatening situations,” said Le Thanh Tinh, the director of the national park.
Vietnam has sought to contain reckless adventure tourism with limited success.
This week a Polish tourist and his Vietnamese guide died while illegally repelling down an 80 meter waterfall at a cave in Lam Dong Province.
Last year, a British backpacker was found dead outside Sapa after setting off alone to climb Fansipan mountain.
The three tourists agreed to pay an undisclosed administrative fine and proceeded to visit other approved destinations in the park.
Son Doong opened to tourists in 2013, four years after members of the British Cave Research Association concluded their initial exploration and declared it the world's largest cave.
The five kilometer-long system, which is 150 meters high and 200 meters wide, contains at least 150 individual caves, a dense subterranean jungle and several underground rivers.
Only one tour operator has been allowed to bring tourists into the cave due to safety and conservation concerns.
In addition to a $3,000 ticket fee, all potential visitors have to meet all strict health requirements to qualify for a valid entry permit.
