Cao Bang, a mountainous border province in northern Vietnam, has long been known as a “hidden green gem” nestled among vast forests. This is a land of majestic waterfalls, endless mountain ranges, and refreshing, pure air throughout the year.
Riding a motorbike along winding roads like Ma Phuc Pass or Khau Lieu Pass, breathing in the scent of wild grass, hearing the murmur of streams, and watching clouds drift over the mountains — all of these create a unique experience found nowhere else.
Ban Gioc Waterfall
Ban Gioc Waterfall, located on the Quay Son River, is considered Vietnam’s most beautiful waterfall and the largest in Southeast Asia. From afar, the sound of the water crashing down echoes through the mountains, like a powerful, grand symphony.
The waterfall stands over 30 meters high and stretches nearly 300 meters wide, forming multiple layers of white foamy cascades that resemble drifting clouds. Standing in front of Ban Gioc, visitors are overwhelmed by its magnificence and the cool mist that envelops the area.
During the rainy season, the waterfall becomes even more majestic and powerful. In the dry season, it flows more gently, revealing mossy green rock formations that look poetic and serene. You can also take a bamboo raft closer to the falls for breathtaking photos or simply to enjoy the tranquility of nature.
Nguom Ngao Cave
Not far from Ban Gioc lies Nguom Ngao Cave, known as a “masterpiece of nature” with a total length of about 2,144 meters, around 900 meters of which are open to visitors.
Entering the cave, you’ll discover countless stalactites and stalagmites in unique and mystical shapes, illuminated beautifully under lights. Some formations look like lotus buds, coral reefs, or cascading waterfalls, sparking endless imagination.
The cave remains cool year-round, providing a pleasant escape from the summer heat. This is an ideal spot to immerse yourself in a magical world, leaving behind the noise and worries of everyday life.
Pac Bo Historical Site
Pac Bo is not only known for its pristine natural beauty but also as an important historical landmark. This is where President Ho Chi Minh lived and worked upon returning to Vietnam in 1941 to prepare for the August Revolution.
The jade-green Lenin Stream, and the towering Karl Marx Mountain behind — all preserved in their original, simple beauty.
The Lenin Stream stands out with its crystal-clear water, where you can see every stone at the bottom. Walking along the stream, listening to birds singing, and watching leaves flutter in the breeze brings a sense of tranquility.
Thang Hen Lake
Thang Hen Lake lies in a large valley surrounded by lush limestone mountains. Remarkably, the area features up to 36 interconnected lakes, creating a rare and fascinating lake system in Vietnam.
The lake surface is calm like a mirror, reflecting the blue sky and surrounding forests — most stunning in the early morning when mist covers the water, creating a dreamy, otherworldly scene.
At Thang Hen, you can paddle a boat to explore the lake’s hidden corners, visit Tay ethnic villages along the shore, fish, forage for wild vegetables, or savor freshly caught stream fish. The peaceful atmosphere makes it an ideal place to “recharge your soul” after stressful workdays.
Thung Mountain
Thung Mountain, located in the remote highlands of northern Vietnam, is a stunning natural formation known for its distinctive circular hole that pierces straight through its limestone peak—earning it the nickname “the eye of the mountain.” Surrounded by rolling green hills, serene rice paddies, and dramatic karst landscapes, the mountain offers a breathtaking view that feels both mystical and untouched. At sunrise or sunset, sunlight streams through the hole, casting a golden glow that enhances its surreal beauty. Still off the beaten path, Thung Mountain remains a hidden gem for adventurous travelers seeking tranquility and raw natural wonder in Southeast Asia.
