Thien Ha Cave: Ninh Binh’s Secret Galaxy Cave for Adventurers

Thien Ha Cave, a hidden cave within Tuong Mountain of Trang An Complex, is renowned for its stunning stalactites and stalagmites. Dubbed “Galaxy Cave”, it remains one of the wildest and most challenging spots of Ninh Binh to reach.

Introduction To Thien Ha Cave

Thien Ha Cave is one of Ninh Binh’s most remarkable hidden gems, within Tuong Mountain in Nho Quan District. Part of the larger Trang An Scenic Landscape Complex, this cave remains relatively untouched by mass tourism, offering a quiet, authentic experience. Its uniqueness lies in its dual dry, wet cave structure, underground river, and glowing stalactites. More than a scenic stop, Thien Ha Cave blends geology, history, and serenity to create an escape that feels both grounded and otherworldly.

History Of Thien Ha Cave

Thien Ha Cave was rediscovered in 2007 and officially opened to visitors in 2010. The route to this hidden gem leads through a peaceful Muong ethnic village, where locals have long lived among the limestone peaks and rice fields.

In 2008, archaeologists found mollusk shells mixed with charcoal deep inside the cave. Later studies uncovered polished stone tools, pottery shards, animal bones, and shells dating to the Middle Neolithic period (9,000–7,000 BP), with signs of human presence as early as 4,000 BP. These findings were documented in 2012 to support the site’s UNESCO recognition.

Beyond archaeology, the cave also served as a military hideout for the Truong Army against the Chinese Invaders during the 9th century. Furthermore, it was also used by locals as a place of worship. Visitors today can still see the remains of old altars and offerings left behind.

Top 3 Iconic Attractions In Thien Ha Cave

Thien Ha Cave boasts a majestic natural stalactite system, formed over millions of years, divided into two main areas: dry and wet caves. Go deeper inside, and you will reach a dark cave, where only flashlights can guide the way.

Dry Cave

The Dry Cave is your first stop inside Thien Ha, stretching 200 meters long and 40 meters wide. It’s filled with shimmering stalagmites and stalactites that catch the sunlight through ceiling cracks, creating shapes like elephants, foxes, and mythical beasts, like a natural stone castle. At the center lies the “Sky Well,” a skylight that symbolizes harmony between earth and sky. The peaceful, almost sacred atmosphere invites you to slow down and simply take it all in.

Wet Cave

Afterwards, a narrow stairway leads you down to a small dock inside the mountain. From here, a boat takes you deeper underground into the 500-meter-long Wet Cave, a silent, winding river that cuts through limestone. This stretch is where the nickname “Galaxy Cave” comes to life.

As your boat glides through the darkness, stalactites hang above and reflect perfectly in the still water below, creating the illusion that you’re floating through a mirrored universe. Many formations have been named by locals, from “Carp Turning into Dragon” to “Hoa Tien Island”, each tied to a story or legend.

The slow boat ride, cool air, and echoing oars make this stretch unforgettable. The further you go, the more immersive the experience becomes, a rare kind of quiet that feels sacred.

Dark Cave

Accessible only on a full tour, the Dark Cave is a continuation of the Wet Cave and perhaps the most surreal part of the journey.

There’s no lighting, only a small torch from your boat rower.. As you shine your light into hidden crevices, you might startle tiny bats fluttering overhead. Aim your torch just right, and you’ll see the cave’s ceiling and its reflection merge into a perfect symmetrical world, giving the uncanny sensation of hovering in space. Near the end of this chamber lies a stalactite formation that resembles the figure of a seated Buddha, quietly illuminated by flickers of torchlight.

Surrounded by still water and thick silence, you might forget where you are entirely. The Dark Cave invites not just observation but introspection.

3 Cultural Experiences You Shouldn’t Miss

Beyond its striking landscape, Thien Ha Cave invites you to slow down and engage with space through your senses. Here are three moments you should not miss during your visit

Admire The Stalactites Of Thien Ha Cave Up Close

As the name suggests, you will encounter sparkling stalactites worth thousands of years, the highlight of Thien Ha Cave, in both the Dry Cave and Wet Cave. The cave is 10–12 degrees cooler than outside, enhancing the experience, especially on hot days.

Step Into The Wet Cave By Boat

Furthermore, you cannot miss the experience of taking a boat into an underground cave and being lost in the limestone ceiling. Hundreds of stalactites reflect off the calm water, creating a surreal, mirror-like world in “Galaxy Cave”. The rocks glow when natural light from the water reflects off them or when a small flashlight shines on them. This quiet, echo-filled atmosphere makes the tour peaceful and immersive.

Taking Photos At The Skylight

Don’t forget to check in at Skylight near the entrance of Dry Cave. Here, natural sunlight changes constantly throughout the day, shining directly through the gaps between the limestone blocks, painting beautiful rays of soft yellow or purple light on the cave floor, creating reflective photos. A magical moment many visitors remember as a highlight.

Inside the cave, sunlight filtering through the dry and wet caves highlights the stalactites that sparkle like scattered galaxies, offering nature photographers mysterious, hazy reflections.

Things To Know Before Traveling To Thien Ha Cave

For a complete and truly memorable journey to Thien Ha Cave, keeping a few practical tips in mind will help you get the most out of your visit.

• At the time of writing, there is no kiosk, cafe, ATM, or restrooms near the cave, so bring drinks, snacks, and cash for tickets, tips, or spontaneous buys along the way, and freshen up at the boat station.
• Wear flat shoes for uneven paths. A light jacket and modest clothing (covering shoulders/knees) to keep you warm in the cool temperature inside the cave, protect against insects, and show respect when visiting temples or sacred pagodas.
• Pack essentials like sunscreen, insect repellent, a hat, and a waterproof bag for your camera to stay protected from the sun and splashes during the boat ride. Though please remember that respecting the natural environment is crucial, so avoid plastic waste to protect the ecosystem.
• Auxiliary lighting and torches provided by the boat rowers, but bringing your own can enhance the experience, especially in the darker sections of the cave, like the one housing the “Buddha” stalagmite. Although flash photography is permitted, always remember to be respectful of cave preservation.
• To avoid the crowds, plan your visit early morning (before 10:00 AM) or late afternoon for better cave lighting. Don’t forget to check the weather forecast to choose the driest and sunniest day.
• When water levels are high, the ceiling inside the cave may come very low in some sections. Be mindful and gently lower your head when needed to stay safe and dry.
• Tipping your boat rower isn’t mandatory, but if their service satisfies your experience, a small gesture of thanks, around 100,000 VND, is a kind way to show your appreciation.
