Ninh Binh is famous for Trang An, Tam Coc, and Mua Cave, the three names that dominate almost every travel guide to the region. But tucked away from that well-worn tourist trail are much quieter places most visitors never even hear about.
Thiên Cung Cave is one of them, a genuinely hidden cave in Ninh Binh that sits secluded behind Bích Động, largely separate from the standard sightseeing route.
One important distinction before anything else: this is not the famous Thiên Cung Cave in Ha Long Bay, which is a large, well-developed tourist cave near Tuan Chau Island with entry fees around 180,000 to 250,000 VND. The Ninh Binh version sharing this name is a small, secluded cave behind Bích Động Pagoda, and the two have nothing to do with each other beyond the shared name.
I found this hidden cave in Ninh Binh entirely by accident while visiting Bích Động, and this guide covers everything I learned about finding it, what it costs, and what the experience is actually like.

What Is Thiên Cung Cave?
Thiên Cung Cave, known in Vietnamese as Động Thiên Cung, is a karst cave tucked into the limestone hills behind Bích Động Pagoda in Ninh Binh. It’s sometimes referred to online as a “secret cave,” which fits the experience of actually finding it more accurately than any formal name could.
As a karst cave, it’s formed from the same limestone geology that defines Ninh Binh’s entire landscape, the same rock that shapes Trang An’s river caves and Tam Coc’s karst towers. But unlike those larger, boat-accessed cave systems, Thiên Cung sits on foot, behind a pagoda, reached by climbing rather than paddling.
What makes this hidden cave in Ninh Binh different from the region’s larger tourist caves is scale and development. There’s no boat queue, no fixed tour schedule, no crowd moving through in a single file. It’s small, quiet, and still feels genuinely undiscovered compared to anywhere else I visited in the region.
Where Is Thiên Cung Cave in Ninh Binh?
The cave sits in Ninh Hải, within Hoa Lư district, directly behind Bích Động Pagoda, roughly 7 kilometers from Ninh Binh city center.
| From | Approximate Distance |
|---|---|
| Ninh Binh City | ~7 km |
| Tam Coc | ~2 km |
| Trang An | ~8 km |
| Bích Động Pagoda | Directly behind it |
Because it sits right behind Bích Động, it’s extremely easy to combine the two in a single visit, and honestly difficult to separate, since reaching the cave requires walking through the Bích Động area first.
How to Get to Thiên Cung Cave
This is one of the more useful sections in this guide, because unlike Ninh Binh’s major attractions, this hidden cave isn’t straightforward to find. I am giving you a google map link for this exact place. It is called Eco point on Google maps.
Getting to Thiên Cung Cave by Scooter
A scooter is the easiest way to reach the area, whether you’re coming from Ninh Binh city or from Tam Coc. The roads leading toward Bích Động are well-paved and simple to navigate, the same route most travelers already take to visit the pagoda itself.
Park at the main Bích Động parking area, the same lot used by everyone visiting the pagoda. From there, you’re on foot for the rest of the journey. I’d recommend a scooter for this trip without hesitation, mainly because it gives you the flexibility to combine it with Tam Coc or other nearby stops on the same day.
Finding the Cave Entrance
This is where things get genuinely tricky, and exactly why I’d call this a hidden cave in Ninh Binh rather than simply an off-the-beaten-path one.
I had no idea this cave existed. I went to Bích Động Pagoda first, and while I was there, I noticed people walking down a set of stairs almost right next to the pagoda itself. There was a wall blocking direct access, so climbing over wasn’t an option. Confused about where these people were coming from, I asked a few of them as they walked down.
They explained that there was technically a way through from inside the pagoda, but the gates on that route were locked. Instead, I needed to leave the pagoda entirely, walk to the parking lot, and look for an entrance to the right of it. At that point, I still had no idea a cave was involved. I assumed I was just looking for a viewpoint or another small temple.
Is Thiên Cung Cave Easy to Find?
No, not really, which is exactly what makes it feel like a genuine discovery rather than another stop on a checklist. It isn’t signposted the way Ninh Binh’s major attractions are, and it doesn’t appear prominently on standard itineraries or tour packages.
Travelers looking for this hidden cave in Ninh Binh should expect to ask locals for directions, as I did, and to accept a bit of uncertainty along the way. That uncertainty is part of the experience. Nothing about finding this cave felt curated or obvious, and that’s rare in a region as heavily visited as Ninh Binh.
Thiên Cung Cave Entrance Fee and Opening Hours
How Much Does It Cost to Enter Thiên Cung Cave?
I paid 30,000 VND per person to enter. There was no separate parking fee beyond what applies to the main Bích Động lot, and no additional guide fee, since the entrance fee itself included a short explanation of the cave from the two women who let us in.
Thiên Cung Cave Opening Hours
There are no officially published opening hours for this cave that I could confirm, which fits the informal, almost undiscovered nature of the whole place. Access seemed to depend on whoever happened to be managing the entrance at the time, two local women who appeared from further down the path shortly after we found the locked gate. I’d treat access as informal rather than expecting fixed daily hours, and I’d recommend visiting during the day rather than assuming any kind of evening access exists.
What Is Inside Thiên Cung Cave?
The Cave Entrance
Getting to the actual cave entrance wasn’t immediate. After making my way past the parking lot and finding the correct path, I started walking up a set of stairs. Partway up, I came across a lake, and for a while I genuinely thought that was the destination itself. It was beautiful, quiet, and completely empty aside from one other couple, so I stopped and took photos there, assuming I’d found what I was looking for.
It was only after continuing further that I came across a sign indicating a cave was nearby. The entrance itself was gated and locked when I arrived, adding another layer of uncertainty to an already confusing search.
The Cave Interior
Two local girls appeared from further along the path and asked if we wanted to visit the cave. After paying the entrance fee, they unlocked the gate and led us inside, explaining details about the cave as we walked through.
The interior wasn’t large, but it was genuinely interesting, natural rock formations, the kind of quiet darkness that makes a small cave feel more significant than its actual size. It didn’t feel like a polished, developed tourist cave. It felt like exactly what it was: a small, local secret being shared with a couple of visitors who’d gone out of their way to find it.
How Dark Is the Cave?
The cave itself was dark enough that having the two girls guiding us with some form of lighting made a real difference. I wouldn’t recommend attempting this without a flashlight or a phone torch as backup, since natural light didn’t reach far past the entrance.
How Long Do You Need at Thiên Cung Cave?
The whole experience, from arriving at the Bích Động parking lot to finishing the cave visit and walking back out, took around 1 to 2 hours for us. That includes the time spent confused about where to go, the stop at the lake, and the cave visit itself once we found our way in.
If you already know exactly where to go, thanks to a guide like this one, you could likely move faster. But I’d still recommend budgeting close to an hour minimum, given the walking involved before you even reach the cave entrance.
Why Is Thiên Cung Cave Considered a Hidden Cave in Ninh Binh?
This genuinely is one of the more overlooked spots in the entire region, and it earns that description for several clear reasons.
It has almost no prominence on standard Ninh Binh itineraries. Search any typical travel guide to the region and you’ll find Trang An, Tam Coc, Mua Cave, and Bái Đính mentioned repeatedly. This hidden cave in Ninh Binh barely registers by comparison.
Its location plays a big part too. Sitting behind Bích Động rather than along a main route means most visitors to the pagoda walk right past the entrance without ever realizing a cave exists back there. I certainly didn’t, until I noticed other people coming down a set of stairs I hadn’t planned to investigate.
The difficulty in finding the entrance reinforces this further. Unlike Trang An or Tam Coc, where signage and established routes guide you the entire way, this cave requires asking locals, backtracking, and accepting some uncertainty before you actually locate it.
It’s also considerably smaller in scale than Ninh Binh’s famous caves. Trang An’s cave system stretches across a boat route lasting hours. Tam Coc similarly involves a boat ride through multiple named caves. Mua Cave, meanwhile, is really a viewpoint climb rather than a cave visit at all. This hidden cave in Ninh Binh is modest by comparison, a single small chamber rather than a sprawling system, but that modesty is part of what makes it feel personal rather than mass-produced.
Fewer tourists follow naturally from all of this. When I visited, there was one other couple and nobody else. Compare that to the queues and crowded boats at Trang An or Tam Coc during peak season, and the contrast is stark.
Most tourists miss this hidden cave in Ninh Binh simply because they don’t know to look for it, and because finding it requires the kind of curiosity and willingness to ask questions that a packed itinerary doesn’t always leave room for.
Things to Know Before Visiting Thiên Cung Cave
Bring a Flashlight
Given the lack of consistent lighting inside, a flashlight or a fully charged phone with a working torch function is genuinely useful, even with a guide leading the way.
Wear Proper Shoes
Between the stairs leading up from the parking area, the path around the lake, and the uneven surfaces inside the cave itself, proper shoes with grip make the whole walk considerably easier.
Don’t Expect a Fully Developed Tourist Attraction
There’s no ticket booth, no signage in English, no polished visitor center. That’s precisely what makes this hidden cave in Ninh Binh worth visiting. Go in expecting something informal and local rather than a developed attraction.
Check Current Access Before Visiting
Access arrangements at a site this informal can shift. Given that there’s no fixed schedule and access seemed to depend on whoever happened to be around the entrance, it’s worth asking locally or checking recent visitor reports before making the trip, particularly if you’re visiting outside standard daytime hours.
Be Careful Inside the Cave
Watch your footing on the uneven surfaces, avoid touching any of the natural formations, and keep noise to a respectful level. This is a small, undeveloped site, and treating it with the same care you’d want it to still have on your next visit matters.
My Experience Visiting Thiên Cung Cave
I hadn’t planned to search for a cave that day. I’d gone to Bích Động Pagoda expecting exactly what most visitors expect: a pagoda, some photos, maybe a walk around the grounds.
Then I noticed people walking down a set of stairs almost directly beside the pagoda. There was a wall blocking any direct route up, so I couldn’t simply follow them back the way they’d come. Confused, I asked a few of the people as they reached the bottom where they’d actually come from. They told me there was technically a path from inside the pagoda, but the gates on that route were locked. Instead, I needed to exit the pagoda entirely, head to the parking lot, and look for an entrance to the right of it.
At that point, I still had no idea a cave was involved anywhere in this. I just started walking up the stairs once I found the correct entrance, following the path without much idea of where it actually led.
Partway up, I came across a lake. It was genuinely beautiful, still, quiet, with nobody around except one other couple. For a while, I assumed this was the actual destination, and I stopped to take photos, fully satisfied with what I’d found.
It was only after continuing past the lake that I came across a sign mentioning a cave. The entrance was locked when I reached it, which felt like a strange anticlimax after the walk to get there. But shortly after, two local women appeared from further down the path and asked if we wanted to visit the cave.
We paid the entrance fee, 30,000 VND per person, and they let us in, guiding us through and explaining details about the cave as we walked. Inside, it wasn’t a massive space, but it was genuinely fascinating, dark, quiet, with natural formations that felt untouched by the kind of tourist infrastructure you’d find at Trang An or Tam Coc.
What surprised me most was simply how much I’d stumbled into without any prior knowledge. I’d gone to see a pagoda and ended up finding a lake, then a hidden cave, then a genuinely memorable hour or two exploring somewhere I hadn’t even known existed that morning.
My favorite part was honestly the uncertainty of the whole thing, not knowing what was up those stairs, not knowing the lake wasn’t the destination, not knowing the cave existed until a locked gate and a hand-painted sign told me it did. The entire experience, from the confusion outside the pagoda to walking out of the cave at the end, took around 1 to 2 hours, and it ended up being one of the more memorable stretches of my entire time in Ninh Binh.
Leaving, I felt genuinely glad I’d asked those strangers coming down the stairs where they’d come from. If I hadn’t, I would have left Bích Động having no idea any of this was back there.
Is Thiên Cung Cave Worth Visiting?
Visit It If…
You enjoy hidden places and don’t mind a bit of uncertainty finding them. You want something away from Ninh Binh’s crowds. You genuinely like caves and natural landscapes rather than just photo opportunities. You’re already visiting Bích Động, since the two are essentially inseparable given the location. You enjoy exploring independently rather than following a fixed tour.
Skip It If…
You want a polished, well-signposted tourist attraction. You don’t particularly enjoy dark or undeveloped caves. You have very limited time in Ninh Binh and need to prioritize the region’s headline attractions. You prefer established sites with clear facilities over informal, locally-managed ones.
My personal verdict: absolutely worth it. This hidden cave in Ninh Binh gave me one of the most genuinely surprising experiences of my entire trip through the region, entirely because I hadn’t planned for it and had no expectations going in.
Can You Combine Thiên Cung Cave With Other Places?
Thiên Cung Cave + Bích Động Pagoda
These two are essentially a package deal given the location. Since the cave sits directly behind the pagoda, visiting one without at least walking past the other isn’t really practical. I’d recommend treating them as a single combined stop rather than two separate destinations.
Thiên Cung Cave + Tam Coc
At roughly 2 kilometers apart, these combine easily in a single day. Many travelers already visit Tam Coc and Bích Động together, so adding this hidden cave in Ninh Binh to that same day requires minimal extra planning, just the willingness to look for the entrance behind the pagoda.
Thiên Cung Cave + Other Nearby Places
Given how close Tam Coc and Bích Động sit to each other, and how straightforward the ride from Ninh Binh city is, this cave fits naturally into any day already built around exploring that part of the region. I wouldn’t recommend stretching further afield on the same day, simply because the search for the entrance and the walk to reach it already take a reasonable chunk of time.
Frequently Asked Questions About Thiên Cung Cave

It sits in Ninh Hải, Hoa Lư district, directly behind Bích Động Pagoda, roughly 7 kilometers from Ninh Binh city center.
Is Thiên Cung Cave in Ninh Binh the same as the one in Ha Long Bay?
No. The Ha Long Bay cave of the same name is a large, well-developed tourist attraction near Tuan Chau Island with entry fees around 180,000 to 250,000 VND. The Ninh Binh cave sharing this name is a small, secluded, informally-managed cave behind Bích Động, and the two are completely unrelated beyond sharing a name.
How much does it cost to visit Thiên Cung Cave?
I paid 30,000 VND per person, which included informal guiding from the two local women managing the entrance.
How do you get to Thiên Cung Cave?
By scooter to the main Bích Động parking area, then on foot. From the parking lot, look for an entrance to the right, then follow the path and stairs up past a lake until you reach the cave entrance.
Is Thiên Cung Cave difficult to find?
Yes, genuinely. It isn’t signposted clearly, and finding it likely requires asking locals for directions, as I did after noticing other visitors coming down a set of stairs near Bích Động Pagoda.
How long do you need at Thiên Cung Cave?
Around 1 to 2 hours total, including the walk to find the entrance, the stop at the lake along the way, and the cave visit itself.

Can you visit Thiên Cung Cave and Bích Động Pagoda together?
Yes, and you essentially have to, since the cave sits directly behind the pagoda and is reached by walking through the same general area.
Conclusion
Thiên Cung Cave is about as different from Ninh Binh’s famous attractions as it’s possible to get within the same small region. No boats, no queues, no polished visitor infrastructure, just a locked gate, a quiet lake, and a small natural cave that two local women were kind enough to open up for a couple of confused visitors who’d wandered further than they meant to.
For travelers who want to step away from the usual tourist trail even for an hour or two, this hidden cave in Ninh Binh is genuinely worth seeking out. What I remember most isn’t the cave itself, as interesting as it was, but the process of finding it: the confusion outside Bích Động, the lake I mistook for the destination, and the moment two strangers appeared and offered to show us something I hadn’t even known to look for.
