The Marble Mountains are not a hill you climb but a hill you go into. Of the five limestone outcrops only one, Thủy Sơn, is developed for visitors, and the reasons to come are inside it: Huyền Không, a chamber with five shafts of daylight in the roof and a Buddha carved in 1960, which served as a surgical station in 1968; Tàng Chơn behind the Linh Ứng pagoda; Vân Thông, a chimney you squeeze up to a hole in the summit rock; Linh Nham with Minh Mạng’s rock inscriptions. The most dramatic cave is not up there at all. Động Âm Phủ, the Hell Cave, is 302 m long, sits at the foot of the hill, and has its own gate and its own ticket – the 40,000-dong ticket you bought at the main gate will not get you in.

The sites compared
Động Huyền Không
The big chamber on the upper terrace, Thượng Thai, entered down twenty-odd steps and lying about five metres below the neighbouring Hoa Nghiêm cave. Five openings in the roof let in light and air; beneath them stands a three-metre Shakyamuni Buddha carved by the stonemason Nguyễn Chất in 1960. The management board gives the vault a circumference of about 25 m and a height of 16 m. Thirty of the 78 ma nhai inscriptions are on these walls.
War history: American units used the cave as a commando training site; in 1968 the liberation forces drove them out, after which it served as a surgical station and a hiding place for the wounded.
included in the 40,000 VND Thủy Sơn ticket
Động Hoa Nghiêm
The antechamber to Huyền Không, right beside the descent. Twenty-one ma nhai inscriptions are cut into its wall, among them the oldest on the hill.
A relief of Quan Âm that predates the pagoda above.
included in the Thủy Sơn ticket
Động Tàng Chơn
Behind the Linh Ứng pagoda on the lower terrace, Hạ Thai: about ten metres long and seven wide, more a small rock valley than a cave, open to the sky through a hole in the roof. The name means roughly “the place that holds the truth”.
Twenty ma nhai inscriptions and traces of the Cham period; the characters Tàng Chơn Động are cut above the entrance.
included in the Thủy Sơn ticket
Động Vân Thông
The chimney on the middle terrace, Trung Thai: a round rock tube running diagonally upwards, narrowing as it goes and ending in a hole in the summit rock roughly a metre across. You haul yourself up against the rock, partly in the dark, one person at a time. A Buddha figure worked out of the rock stands inside the tube.
Come out of the top and you are standing on the summit rock with the coast below. Not for anyone claustrophobic, in sandals, or carrying a rucksack.
included in the Thủy Sơn ticket
Động Linh Nham
A narrow, high cleft on the upper terrace, easy to walk past and therefore usually empty. Minh Mạng had its name written into the rock in 1837; three ma nhai inscriptions are recorded here.
One of seven cave names that go back to the emperor’s own hand.
included in the Thủy Sơn ticket
Động Âm Phủ (Hell Cave)
The longest cave on the site at 302 m, with a vault 45 to 50 m high in places. It lies at the foot of Thủy Sơn and has its own gate and its own desk. Past the bridge over the “river Nại Hà” the route divides: down into hell, through twelve gates lined with tableaux of the judgement of souls, or up a steep daylit stairway to “heaven”.
The cave in its present form, sculptures and all, dates from a conversion carried out between 2003 and 2006. In July 2011 the German caver Michael Laumanns surveyed it with instruments; the French doctor Albert Sallet had described the shaft back in the 1920s.
20,000 VND extra ($0.76 / €0.65)
Động Quan Âm (Kim Sơn)
The one genuine dripstone cave in the massif: 64 m long, 5 to 7 m wide and about 7 m high, under the neighbouring hill Kim Sơn behind the Quán Thế Âm pagoda. The monk Thích Pháp Nhãn found it in 1956 behind a rock face that hid the entrance. Inside, a flowstone has taken the shape of a life-size Quan Âm, and there is an underground lake.
Not covered by the Thủy Sơn ticket and skipped by nearly every tour. It is the centre of the Quán Thế Âm festival on the 19th day of the second lunar month.
no management-board ticket; the pagoda grounds are freely accessible

Tours to the Marble Mountains from Da Nang and Hoi An
Worth saying plainly: admission here is almost free. 40,000 VND for the hill is about $1.53, the Am Phu Hell Cave is 20,000 VND on top, the lift 15,000 VND each way – all of it together comes to roughly $3.43. You are not booking a tour for access. You are booking it for the driving, the explanation and the planning you do not have to do. On GetYourGuide nearly every listing is a combined half-day trip from Da Nang or Hoi An – the Marble Mountains with the Lady Buddha, with Monkey Mountain (Son Tra) or with Hoi An – and together they carry more than 9,400 reviews. The most booked is the small-group half day “Lady Buddha, Marble Mountains & Am Phu Cave”: 4.5 hours, 4.7 stars from 6,720 reviews, from $22.02. A near-identical Monkey Mountain version rates 4.9 from 1,417 reviews at $19.87, and from Hoi An a five-hour small-group trip starts at $16.48. Bolt the Marble Mountains onto Ba Na Hills and the Golden Bridge and you are at $68.18 for a nine-hour day, at which point the hill is one stop of three. Read the title before you book: the half-day tours name Am Phu Cave explicitly, the long combinations to My Son or Ba Na Hills usually do not. Making your own way needs no booking at all – city bus route 01 between Da Nang and Hoi An stops here, Grab from Da Nang usually runs 80,000 to 200,000 VND, and tickets are sold for cash at the desk with no time slots and no advance sale.

Opening hours and best time
The management board’s own fares page says «Từ 07g00 đến 17g00 hằng ngày» – 7am to 5pm, every day, no closing day. That is the only sourced figure. A great many English pages print 7am to 5.30pm, and one even says 6am to 6pm; no announcement from the board supports either. There is no published last-admission time either. In practice the desks at both gates stop selling before 5pm and the lift brings the last visitors down shortly after. Turn up after 4pm and the visit will be rushed. On a handful of public holidays the city waives admission entirely – in 2025 those were 29 March (Đà Nẵng Liberation Day), the Hùng Kings’ commemoration on 7 April and National Day on 2 September.
When it is quietest
Early. The gates open at 7am, the first coaches from Đà Nẵng and Hội An arrive around 10, and from midday there are queues at the lift, on the stairs and at the cave mouths. Between 7 and 9 you have the hill almost to yourself, the air is cool and the stone has not yet heated up. Huyền Không has a second window of its own: from roughly 9 to 11 the sun stands so that the roof shafts throw hard beams onto the altar, which is the photograph most people came for. By season, February to April is the most comfortable; May to August is hot and humid, and September to November brings the rain that turns the marble steps treacherous.
Who it suits
With children
Thủy Sơn works well with school-age children if you take the lift, although the upper level still means uneven rock steps. Âm Phủ is the part children remember and the part to think about first: the tableaux show the Buddhist hell very literally, with animal-headed demons sawing, boiling and impaling the condemned. Some children love it, some do not. The climb to “heaven” is steep and exposed in places and is not for small children.
Minimum age
None. Under-6s go free everywhere on the site.
Wheelchair
No. The lift does put you on the plateau by the Linh Ứng pagoda, but from there everything continues over steps, thresholds and sloping rock, and not one of the caves is accessible. Âm Phủ has a level entrance but a wet, uneven, slippery floor and is not wheelchair-accessible either.
Pushchair
Not realistic. With a toddler, bring a carrier.
Dogs
No published rule on dogs. The pagodas are working monasteries, where bringing animals inside is not done.
Claustrophobia
Two places are difficult. Vân Thông is a rock tube that narrows as it rises, dark and warm, wide enough for one person at a time and in places only climbable using your hands. In Âm Phủ the openings to the individual hell gates are tight enough that you turn sideways; the air is still, the walls drip, and turning back in a queue is awkward. Skip both and you still get the heart of the visit – Huyền Không is wide and full of light.
What to wear
Shoulders and knees covered, or you will be turned away at the pagodas; staff will usually lend a wrap. Shoes, hats, sunglasses and rain capes come off before you enter a prayer hall. For the walking, the opposite applies: closed shoes with grip. The marble steps have been polished by millions of feet and are glassy when wet – flip-flops are the single commonest cause of falls here.
Photography
Allowed, caves included. In the prayer halls the usual courtesy applies: do not photograph into a ceremony, and do not photograph monks without asking.
Getting there
By public transport
The yellow city bus, route 01, runs from Đà Nẵng central bus station along Lê Văn Hiến to Hội An and stops at the Marble Mountains. It runs roughly 5.30am to 6pm every 15 to 30 minutes and takes 60 to 80 minutes end to end; foreigners are usually charged around 30,000 VND ($1.14). From the Non Nước stop it is about ten minutes on foot to the gates.
By car
Car parks sit directly at both gates and at the Âm Phủ entrance, generally 5,000 to 10,000 VND for a motorbike or car. The car parks are also where the stone-carving shops start working on you; say no clearly and keep walking.
From the nearest city
From central Đà Nẵng it is 8 to 9 km along the coast road, 15 to 25 minutes, and roughly 80,000 to 200,000 VND ($3.05–$7.63) by Grab or taxi depending where you start. From Hội An it is about 20 km and 25 to 35 minutes; reported Grab fares run from 100,000 to 350,000 VND ($3.82–$13.35), a spread that moves with the hour and the vehicle class. A rented scooter is the cheapest way of your own, but you need a licence Vietnam recognises. Đà Nẵng airport (DAD) is about 20 minutes away.
Tips for your visit
- Two tickets, three desks. The 40,000 VND Thủy Sơn ticket covers the hilltop. The Hell Cave costs 20,000 VND at its own gate at the foot. If you want the Hell Cave, buy it there – the hill gates do not sell it.
- Do the lift arithmetic. 15,000 VND buys one direction, not a return. Ride up, walk down the 156 steps to Gate 1, and you pay once and see the Tam Thai pagoda and the Vọng Giang Đài viewpoint on the way.
- Pick your gate by what you want to see. Gate 1 (156 steps) leads to Tam Thai and straight into the Hoa Nghiêm and Huyền Không area. Gate 2 (108 steps or the lift) leads to Linh Ứng, the Xá Lợi stupa, Tàng Chơn and the Vọng Hải Đài viewpoint. A path links both ends up top, so the choice is about where you start, not what you miss.
- Be at Huyền Không between 9 and 11. That is when the light comes through the five roof openings and reaches the altar. Outside that window it is a large dark hall.
- Proper shoes, not sandals. The marble is polished smooth and slick when wet. You take them off at the prayer halls anyway – you need them for everything in between.
- Cover shoulders and knees. It is enforced at the pagodas, and arriving in a vest means borrowing a wrap. Hats and sunglasses come off at the door.
- Have a phone torch ready. The back of Âm Phủ and the chimney of Vân Thông are only patchily lit.
- Do not treat Âm Phủ as an afterthought. Allow 20 to 30 minutes at least. It is hot, wet and tight, and the stairway to “heaven” is steep. Decide about children and claustrophobia before you buy the ticket, not halfway in.
- Be careful buying marble in Non Nước. Small souvenirs are frequently stone dust and resin rather than stone, and large shipped orders turn up on TripAdvisor year after year with the same story: damaged on arrival, veneer over filler, a bill well above the price agreed. If you buy, buy small, pay cash and carry it away.
- Bring water and come early. The coaches start arriving at 10, and by midday the pale rock is an oven.

History in brief
- The five knolls are remnants of limestone and marble that once stood as islands off the coast and were joined to the mainland only as the Quảng Nam plain silted up. The cavities are tropical karst chambers open to the sky rather than the stalactite systems European visitors expect.
- From the Cham period come sandstone figures found in the caves, along with ceramics and brick. An excavation on the southern side of Thổ Sơn in 2000 turned up Chinese trade ceramics, Sa Huỳnh material and Cham bricks matching finds from Cù Lao Chàm and Trà Kiệu.
- The Tam Thai pagoda goes back to the 17th century; the Chinese-born Zen master Hưng Liên led it towards the end of that century. It was destroyed during the Tây Sơn years.
- In 1825 Emperor Minh Mạng had Tam Thai rebuilt in brick and tile and granted it an imperial tablet; he toured the hill on the same journey, and his sister withdrew here as a nun. In 1826 he endowed the temples with bells and statues.
- In 1837, the eighteenth year of his reign, the names Ngũ Hành Sơn, Thủy Sơn, Kim Sơn, Mộc Sơn, Thổ Sơn and Dương and Âm Hỏa Sơn were fixed and written into the rock, following the doctrine of the five phases. Seven cave names, Huyền Không, Tàng Chơn, Vân Thông and Linh Nham among them, are in the emperor’s own hand.
- The French army doctor Albert Sallet published the fullest early account in 1924 in the Bulletin des Amis du Vieux Huế: “Les Montagnes de Marbre”, 195 pages with 43 plates of photographs, sections and maps of the caves and pagodas.
- In the war against France, Huyền Không served as a clandestine base. In the American war, US units set up a commando training site in it. In 1968 the liberation forces drove them out, and the cave then became a surgical station and a hiding place for the wounded. In the early hours of 23 August 1968 a unit under Phan Hiệp – known as Phan Hành Sơn – attacked from here; the formation was awarded a first-class combat decoration for it.
- The site was listed as a national monument in 1980. On 24 December 2018 the prime minister raised it, by decision 1820/QĐ-TTg, to the class of special national monuments (di tích quốc gia đặc biệt).
- On 26 November 2022 the Asia-Pacific committee of UNESCO’s Memory of the World programme entered the 78 ma nhai rock inscriptions of Ngũ Hành Sơn in its regional register: texts in Chinese and Nôm script from the 17th to the 20th century, by emperors, officials, monks and travellers. The certificate was handed over in Đà Nẵng on 1 March 2023. This is emphatically not a World Heritage listing.
- Quarrying stone from the hills has been banned since 1990 to save the monument. The stone-carving village of Non Nước at its foot, national intangible cultural heritage since 2014, has worked ever since with material trucked in from Thanh Hóa, Nghệ An and Thái Nguyên and with imports – more than 25,000 tonnes a year.
Frequent questions
How much does it cost to visit the Marble Mountains in 2026?
Thủy Sơn, the main hill, is 40,000 VND for adults, about $1.53 or €1.30; students pay 10,000 VND and under-6s nothing. The Hell Cave, Âm Phủ, is a further 20,000 VND at its own gate. The lift adds 15,000 VND per direction. Do all of it and you spend 90,000 VND, roughly $3.43 or €2.94. Converted at the Vietcombank rates of 20 September 2026.
Is Am Phu Cave included in the Marble Mountains ticket?
No, and this is the mistake English pages make most often. Âm Phủ is not on top of the hill but at the foot of it, with its own entrance, its own desk and its own 20,000 VND ticket. The 40,000 VND Thủy Sơn ticket will not get you in, and the Âm Phủ ticket will not get you up the hill.
Is the elevator price per ride or for the return trip?
Per direction. The board prices it at 15,000 VND «per lượt» and the city tourism portal adds 30,000 VND «khứ hồi» for the return. Several English sites sell the 30,000 as a single fare, and at least one quotes 60,000 VND return. The practical answer: ride up, walk down, pay once – and you get the other pagoda thrown in.
How many steps are there, and which staircase goes where?
Two staircases, both on Huyền Trân Công Chúa street. Gate 1 has 156 steps and reaches the Tam Thai pagoda, which puts you next to the Hoa Nghiêm and Huyền Không caves. Gate 2 has 108 steps and reaches the Linh Ứng pagoda, the Xá Lợi stupa, Tàng Chơn and the Vọng Hải Đài viewpoint; the lift is here too. A path joins both ends on top, so you are not locked into one side.
Does the lift take me all the way up?
It takes you onto the plateau by the Linh Ứng pagoda – the hardest part, but not the whole hill. After that it is rock steps, thresholds and sloping slabs to reach the caves and viewpoints. If you genuinely cannot climb, the lift still buys you Linh Ứng, the stupa and Tàng Chơn; Huyền Không and Vân Thông need more steps.
Do I need to book tickets in advance?
No. There is no online sale by the management board and no timed entry. You pay cash in dong at the desk. Nothing sells out; the only problem is the crowd between 10am and 2pm.
How long should I allow?
Two to two and a half hours for Thủy Sơn with the four caves, both pagodas and the viewpoints. Âm Phủ adds 20 to 45 minutes, the Non Nước carving village another half hour. If you only take the lift and look at Huyền Không, an hour is enough.
Can you climb all five Marble Mountains?
No. Only Thủy Sơn is developed and ticketed. Kim Sơn has one worthwhile, freely accessible target in the Quán Thế Âm pagoda and its dripstone cave. Mộc Sơn, Thổ Sơn and Hỏa Sơn have no visitor trails. The line about five hills full of walking trails, which travels from blog to blog, describes something that does not exist.
Is the Hell Cave suitable for children?
That is your call. The tableaux depict the Buddhist hell without softening it: animal-headed demons sawing, boiling and impaling the condemned. Plenty of children find it thrilling, some find it upsetting. The practicalities matter too – it is tight, hot and humid, the floor is wet, and the stairway to “heaven” is steep and exposed in places.
What should I wear?
Shoulders and knees covered, or the pagodas will turn you away; a wrap is usually available to borrow. Shoes, hat and sunglasses come off before a prayer hall. For the walking itself, closed shoes with grip: the marble steps are polished and lethal when wet, which is why sandals cause most of the falls here.
Do I need a torch?
Not for the Thủy Sơn circuit, which is lit or daylit throughout. For the back of Âm Phủ and the chimney of Vân Thông a phone torch is worth having, because the lighting is patchy and the floor is uneven.
When is it quietest?
Between 7 and 9am. Coaches from Đà Nẵng and Hội An start arriving around 10, after which the lift and the staircases back up. For the light shafts in Huyền Không, 9 to 11 is the window – a compromise between good light and the first wave of groups.
How do I get there without a car?
The yellow city bus, route 01, runs between Đà Nẵng and Hội An and stops at the Marble Mountains: around 30,000 VND for foreigners, every 15 to 30 minutes from 5.30am to 6pm, and about ten minutes on foot from the Non Nước stop. Grab is easier: 80,000 to 200,000 VND and 15 to 25 minutes from Đà Nẵng, 100,000 to 350,000 VND and around half an hour from Hội An.
Is it possible with a wheelchair or a pushchair?
In practice, no. The lift solves the ascent, but above it everything continues over steps and rock thresholds, and none of the caves is accessible. Âm Phủ has a level entrance but a wet, uneven floor. With a small child, a carrier works where a pushchair does not.
Is the story about the Viet Cong field hospital true?
In substance yes, but not in the form it is usually told. The management board’s own account says American units first used Huyền Không as a commando training site. The liberation forces took the cave in 1968, and only then did it serve as a surgical station and a hiding place for wounded soldiers. The picture of a hospital operating in secret beneath American noses for the whole war does not match the official record.
Should I buy marble carvings at Non Nuoc?
If you do, buy small, pay cash and carry it out yourself. Many of the small souvenirs are stone dust bound in resin rather than stone – scratch the underside and white powder comes off. For larger pieces with shipping, the same complaints recur across years of TripAdvisor reviews: damage on arrival, marble laminate over filler, invoices above the agreed price. The stone no longer comes out of the hills in any case: quarrying was banned in 1990, and the raw material now arrives from Thanh Hóa, Nghệ An and Thái Nguyên.
