Chu Bluk cave complex in Krong No district - Dak Nong province, about 40 km to the south of Buon Ma Thuot, is the longest volcanic cave in Southeast Asia. The cave is known as an iconic destination of the Central Highlands.

Discovered in 2014, the cave remains unknown for most tourists, which helps maintain its inherent wildness.

The cave lasts from Dray Sap waterfall to Buon Choah cave, about 25km. The cave system is divided into more than 100 large and small caves thanks to the flow of lava millions of years ago, hidden in basalt.

According to researchers, the process of forming the caves took place 3,700 years ago by volcanic eruptions.

The temperature inside the cave remains stable at 25 Celcius degree all year round. Therefore, tourists can visit the cave at any time. Locals recommend discovering the location in late spring and summer due to the sunny weather and low possibility of rain, allowing tourists to easily approach the cave and take stunning photos.

Spring is the season of festivals in Dak Nong, so visitors can experience diverse cultural activities of the province.

In the dry season, tourists have to pass vast cornfields before reaching the cave and a 25-kilometer path along the river.

The cave's entrance is a round crater with a diameter of 600m, a depth of 60m.

To enter the cave, tourists have to pass a difficult road in the jungle. Passing the entrance, tourists are surrounded by an airy and mysterious space. While the jungle outside is dry and dark, the ecosystem inside the cave surprises tourists with its diversity and green color.

If closely looking at the surface of basalt rocks, tourists can learn the formation of the cave from millions of years ago. Along the way, there are rocks with rough shapes formed from lava pouring out of the crater. The cave was created in the same way, according to scientists.

Getting down the cave, tourists are welcomed by a grave wall covered with layers of ferns that looks quite fancy and mysterious. Lava rocks lie everywhere on the road leading deeper into the cave. The yellow and red flows of lava can be seen on the ground, while the cave's wall is decorated with lines of different shapes.

Streams of light shine through the leaves and layers of dust and mist. The light, together with volcanic rocks covered with layers of moss creates a spectacular yet unusual scene.

Chu Bluk is easy to recognize from afar because of its special position. The cave, located in the middle of a large empty hill area, stands out with its stunning scenery.

Due to the complex system, the cave is difficult to access. To ensure safety, tourists should contact the forest management board and hire local tour guides to show them the way.
