Located along National Highway 20 towards Da Lat and about 120km from Ho Chi Minh City, the volcanic cave system was discovered more than 10 years ago in the teak forest in the Dinh Quan and Tan Phu districts of Dong Nai. Recently, many tourists have flocked to the area to explore its beauty.

The largest cave in the Dong Nai area has a width of about 6 meters, a length of 200 meters, and a height of about 3 meters, forming a solid and majestic cave arch. To explore it, visitors need to use specialized flashlights.

Since it remains pristine and undeveloped, the entrance is difficult to access with many sharp rocks. Inside, the cave is dark, with only a bit of light coming from the cave's entrance.

According to experts, the cave was formed after volcanic eruptions about 15 million years ago. Its walls feature many partitions that form unique patterns.

The deeper parts of the cave are home to millions of bats, that is why locals call it the Bat Cave. The atmosphere inside is described as pleasant, not foul-smelling like other bat caves.

Another branch of the cave under the teak forest has an entrance wide enough for just one person to pass through, but inside, it feels like a fortress. The roots of trees penetrating deep into the cave, together with the flashlight's light create an enchanting scene.

When exploring the cave, many visitors feel as if they are walking through an "underground tunnel," surrounded by unique natural architecture and a cool atmosphere.

The cave's ceiling mesmerizes visitors volcanic stone formations. "This is my first time exploring a volcanic cave, and I am amazed by the natural beauty right beneath the villagers' fields," said Lan, a visitor from Ho Chi Minh City.

The more deeply one goes into the cave, the more challenging the path becomes. Visitors have to squeeze through narrow rock crevices to move forward.

The cave's end is quite narrow, with many small passages on both sides leading to other unexplored directions.

The Dong Nai tourism sector is working with travel agencies to plan guided tours to explore this cave.

Located within the teak forest area, the cave entrance is covered by thick grass, known only to locals. Visitors are free to explore, but it is recommended to contact someone familiar with the area for a safe guide and not to go alone.

With nearly 150 hectares spanning across Tan Phu and Dinh Quan districts, the teak forest in Dong Nai is currently the largest of its kind in Vietnam.
