Located in the vast forest of Ba Bể District, Bắc Kạn Province, Thẳm Phầy Cave in Nà Slải Village, Hoàng Trĩ Commune beckons adventurous travellers to conquer its pristine and mysterious beauty.

Stopping on the concrete road connecting the villages, we walked to the only path along the mountainside to explore the cave.

The sudden rain made the path slippery, a bit more dangerous than usual when walking on a variety of terrain. We crossed through terraced fields, springs, bamboo bridges and thick bushes to reach the cave.

The two kilometres of weaving in the forest made us tremble due to the vast deserted space.

According to Hoàng Văn Cơ, a local in the village, Thẳm Phầy in Tày language means “fire” cave, which was discovered by locals many years ago. It is about 5-6km long. 

Thẳm Phầy cave was likely formed due to volcanic eruptions and the tectonics of limestone mountains passed by underground rivers to cause erosion, combined with water droplets having the minerals of limestone dripped after millions of years, creating many beautiful stalactites and stalagmites.
