Discovered by Ho Khanh in 1990, but explored and measured by the British-Vietnamese team in 2009, Son Doong is the world's largest natural cave.
Located in Phong Nha-Ke Bang National Park, it offers a grand spectacle with its interior jungle and unique formations. The expedition, though costly (around 3,000 USD for five days), is an extraordinary experience.

A jewel of UNESCO World Heritage since 2003, Phong Nha-Ke Bang National Park is home to Phong Nha Cave.
Here, time seems to stand still, with each stalactite and stalagmite telling a millennia-old story. Light, in a hypnotic ballet, reveals the hidden beauty of the cave, inviting a journey into the depths of the Earth. A guided exploration unveils the first 1,500 meters of this natural sanctuary.

Hang Toi, or Dark Cave, is a raw gem of Phong Nha-Ke Bang National Park. Here, adventure is experienced by the light of the headlamp, in a maze of galleries where water and rock merge. Less explored, it offers an authentic experience, away from the beaten paths. Mud baths invite relaxation, while zip-lining and kayaking promise thrills.

Located in the Bo Trach district, near the border with Laos, in Phong Nha-Ke Bang National Park, Hang En is the second largest cave in Vietnam and the third largest in the world. It opens up to the underground world through three monumental entrances. The largest, an arch 120 meters high and 140 meters wide, sets the tone for this extraordinary exploration. Discovered in 1994, Hang En is a labyrinth of underground rivers and rock formations sculpted by time. A 22 km hike through the jungle is the price to pay to discover this gem, where the spectacle of swallows flying over the place is matched only by the beauty of the site. Camping for a night on the white sandy beach, in the heart of the cave, is an unforgettable experience.
 

Tham Phay, formerly Lo Mo Cave - Mr Linh's Adventures

In the heart of Ba Be National Park (about 200 km north of Hanoi), far from urban hustle, Tham Phay, the "Son Doong of the North," reveals its wonders.
Access, a 4-hour hike through lush nature, is well worth it. But once inside, the spectacle matches the effort: grandiose rock formations, an underground river with crystal-clear waters, and the promise of an unforgettable swim. Tham Phay is an invitation to adventure, a timeless exploration in a wild beauty setting.

This exceptional diversity of underground labyrinth offers a range of adventures for every taste.
