A Hiking Guide to Paradise Cave and Dark Cave in Phong Nha

Paradise Cave Hike Itinerary

Paradise Cave is an impressive limestone cave discovered in 2005 and later surveyed by British cave explorers. The cave extends for around 31 km, with enormous chambers reaching up to roughly 100 meters high and 150 meters wide in places.

Paradise Cave is definitely an impressive cave to explore and one that is pretty accessible. Regular visitors can explore the first kilometer on a well-maintained wooden boardwalk without a guide. As of 2026, I would budget around 270,000 VND per adult for the standard visit, as current published prices cluster around 250,000–270,000 VND depending on whether the electric buggy is included in the quoted ticket price.

For those who want to go beyond the well-lit tourist section, there is a separate guided Paradise Cave 7 km Adventure. The route continues beyond the end of the boardwalk into the undeveloped section of Paradise Cave, eventually reaching the skylight cavern known as Heaven Well before you backtrack to the entrance. Do not confuse this with Dark Cave (Hang Toi), which is a completely separate cave near Paradise Cave.

I went on a shared group tour, and there were five of us together with one awesome and hilarious caving guide. We were picked up from Phong Nha and transported to the ranger office in front of Paradise Cave to be fitted with caving gear.

We were given a helmet, a military-style jacket and pants, a pair of boots, and a headlamp, and off we went into the Paradise Cave. The tourist section of the cave already had me surprised by the sheer beauty of all the rock formations found inside.

The first section of Paradise Cave is extremely well-lit, with well-maintained wooden boardwalks that took us around some of the most beautiful rock formations out there.

To think that it took an immense amount of time for all these rock formations to become what they are today is mind-blowing. Each rock formation has a signboard that explains what the formation resembles, but my guide told us that it was all bull and that more exciting things awaited us beyond the tourist section.

After we are done with the tourist section, our guide led us across a boundary and into the darkest and deepest area of the cave. Now, let the fun begin!

With our headlamps, we walked deeper into the unlit section of Paradise Cave step by step, marveling at the sheer scale of some of these caverns. One of them was so massive that my guide told me it could fit an entire sports stadium inside.

Some of the rooms in the cave were so big that our guide told us to close our eyes and start running at full speed for 10 seconds, which we did, and we barely made it halfway to the end of the room.

Along the way, we saw some really incredible rock formations, from a massive stalactite to a giant sandstone dome that glittered as we moved our headlamps around.

After about 2 hours, we eventually arrive at our destination: the secret cavern with a giant daylight hole on the roof of the cave, dripping water from the rain that accumulated in the forest above.

It was quite a sight to behold. We had lunch there and swam around the little rainwater lake inside the cave to freshen up for about an hour before we started making our way back to the entrance.

It was a hell of an adventure and a great way to do something unique in Vietnam that isn't all about taking the perfect Instagram photos in places like Hoi An, etc. If you are looking for a great adventure to do in Vietnam, going caving at Paradise Cave is definitely worth considering.

How To Get To Phong Nha?

You can easily reach Phong Nha via trains from Hanoi to Dong Hoi, with overnight services generally taking around 9–11 hours depending on the train. From Dong Hoi, Phong Nha is another 45 km away.

You can also fly from Hanoi or Ho Chi Minh City to Dong Hoi Airport. Direct flights still operate on both routes in 2026, with the flight itself taking roughly 1–1.5 hours. Airfares fluctuate considerably, so I would compare them with the sleeper train for your dates.

Once you arrive in Dong Hoi, the cheapest option is the local B4 bus from Dong Hoi Bus Terminal to Phong Nha, currently costing around 35,000–50,000 VND and taking roughly 60–90 minutes. There is no public bus directly from Dong Hoi Airport to Phong Nha, so from the airport you can take a taxi to the bus terminal, arrange a hotel pick-up, or organize a private transfer directly to Phong Nha.

How to Get to Paradise Cave?

If you are planning to visit only the standard 1 km section of Paradise Cave, you can rent a motorbike from your accommodation and drive directly to the cave. From Phong Nha village, allow roughly 25–30 minutes for the ride. The standard cave can be visited independently without a guide.

If you want to continue beyond the first kilometer and do the 7 km Paradise Cave adventure described in this guide, you will need to join an organized guided tour. This deeper route involves rough, unlit terrain, water crossings, and sections where specialist caving equipment is required.

The experience described in this guide is now generally sold as the Paradise Cave 7 km Adventure. As of 2026, local operators advertise the full-day trip from around 2,500,000 VND per person, including a guide, caving equipment, lunch, drinking water, entrance logistics, and hotel transfers. You can book the tour here: Paradise and Dark Cave tour.

What to Know Before Hiking the Paradise Cave 7 KM Route?

• The first section of Paradise Cave does not require any preparation or a guide to visit, as you will be walking on wooden boards on a designated path the entire time.
• The 7 km route beyond the first section of Paradise Cave is only accessible as a guided adventure tour. Current operators provide the necessary caving equipment and protective gear, which typically includes a helmet, headlamp, appropriate footwear, and other equipment needed for the route.
• The cave can get very muddy, slippery, and wet, so be sure to keep your camera gear safe with you while hiking. A regular bag should be fine, but just in case, pack a bag cover for an extra layer of protection for your camera gear.
• When I did the 7 km Paradise Cave route, it took us around 2 hours to reach the skylight cavern, where we had our packed lunch, went for a swim, and then hiked back the same way. Current tours still follow this general full-day format, although the exact route can change with water levels and weather. Expect slippery rocks, mud, water crossings, and uneven terrain.
• If you are not very active, you can still visit Paradise Cave and stick to the first section of the cave, which isn't physically demanding at all. If you are active and looking for a challenge, the hike inside Paradise Cave is perfect for you.

What To Pack for the Paradise Cave 7 KM Adventure?

For visiting the standard tourist section of Paradise Cave, you do not need specialist caving gear. You will be walking along a wooden boardwalk, although the approach to the cave involves a climb and plenty of steps, so comfortable walking shoes are a good idea. Allow roughly 2–3 hours for the complete visit, including the approach and the first kilometer inside the cave.

For the 7 km Paradise Cave adventure, the tour operator provides the specialist caving and safety equipment, as well as lunch and drinking water on most current tours. I would bring quick-drying clothes, swimwear, a towel, a change of clothes, extra snacks, and a waterproof case or dry bag for anything you want to keep protected inside the cave.
