Quan Ba – The Fairy Land in Ha Giang | Mr Linh's Adventures
If you are currently planning your road trip on the legendary
Ha Giang Loop, you probably already have visions of dizzying mountain passes, endless terraced rice fields, and epic selfies at the
Ma Pi Leng Pass.
But did you know that right at the beginning of the adventure, just after surviving the famous "
Heaven’s Gate" of
Quan Ba, lies a subterranean kingdom worthy of an adventure movie?
Welcome to
Lung Khuy Cave (or
Động Lùng Khúy in Vietnamese). Strap on your helmet, we’re heading underground!
What is it, where is it, and how do you get there?
Lung Khuy Cave is located in the Quan Ba district, about 10 km from the town of Tam Son. It is the perfect stop for your very first day on the loop.
The ride: From the main road, you’ll veer off onto a small, winding path that snakes through grandiose karst landscapes and local Hmong villages. The ride to get there is worth the detour all on its own!
Earn your stripes: Once you’ve parked (expect to pay a few thousand Dong for parking), you will need to hike about 1 to 1.5 km up a paved pathway hugging the mountainside.
Pro-tip: Don't try to be a hero in flip-flops. Wear good sneakers. Your calves will thank you, and it will keep you from slipping cartoon-style on the damp steps.
Dong Lung Khuy - A hidden gem along the Ha Giang LoopThe romantic legend of Lung Khuy
Because no beautiful cave in Vietnam is complete without a local legend, here is a little story to help you shine at your next hostel family dinner:
According to Hmong folklore, the region was once struck by a terrible drought. A celestial dragon, feeling pity for the locals, descended to Earth and settled in the cave to make a fresh water spring gush out.
But that’s not all! The dragon fell madly in love with a beautiful local Hmong girl. They lived happily ever after, had many children, and today, the cave has become a sacred place where couples come to ask for blessings for their love (and a bit of rain for the crops, which is also quite important).
Why you are going to love it
The best natural air conditioning in Vietnam
Inside, the temperature instantly s to a cool 18°C to 20°C. After sweating on your motorbike under the blazing sun or climbing up the access path, stepping into Lung Khuy feels like walking into an air-conditioned supermarket on a scorching summer day. Absolute bliss.
A forest of stalactites and stalagmites
Discovered only recently in 2015 and opened to the public shortly after, the cave is incredibly well-preserved. Along a well-maintained 300-meter wooden walkway, you’ll weave through limestone formations millions of years old.
Some look like monster heads, others like stage curtains or ancient temple columns. Keep your eyes (and your imagination) wide open!
"Club-style" light shows
Vietnamese tourism loves illuminating caves with colorful neon lights. Lung Khuy is no exception! Yellow, blue, green, purple... The lighting gives the place a magical, slightly psychedelic vibe. It's absolutely perfect for unique Instagram shots.
