Best Scuba Diving in Nha Trang: Dive Sites, Costs & Practical Guide 2026

Nha Trang is an accessible place to get started with scuba diving. A short boat ride from the city brings you to the bay's coral reefs, rocky areas, and sandy bottoms.

Certified divers have a wider range of options regarding depth and terrain. However, rather than insisting on a famous dive site at all costs, it is best to let your personal experience and the day's sea conditions determine your itinerary.

According to PADI, the waters of Nha Trang are home to reef fish, sea slugs, and corals, with the possibility of spotting stingrays or cuttlefish. The following article covers what you need to know before booking a dive trip, including destinations, costs, and pre-flight waiting times.

1. Is Nha Trang good for scuba diving?

Nha Trang is quite suitable for first-time divers, newly certified divers and those who enjoy recreational exploration of coral reefs.

Dive centres in the city currently offer a variety of programmes. Those who have never dived before can sign up for an introductory experience with an instructor. Certified divers can join recreational diving trips or enrol in a PADI or SSI course if they want to continue their training.

The most important factor to consider, however, is the weather.

Wind, waves, rainfall and water visibility can change from day to day. Nha Trang Diving Club currently considers around April to October to be a more favourable period, but dive sites are still selected according to sea conditions on the morning of the trip.

For beginners, instructors generally prioritise sheltered areas with moderate depths. More experienced divers should ask about the terrain and expected depth in advance to determine whether the trip is suitable for their certification level.

2. Which diving experience suits you?

What is your experience level?	Recommended option	What to look for
First-time diver	Discover/Try Scuba	Shallow training and close instructor supervision
Newly certified diver	Guided two-dive trip	Moderate depths and manageable conditions
Experienced diver	Site-specific fun diving	Deeper terrain and rocky formations
Macro enthusiast	Reef and rocky sites	Nudibranchs and smaller reef species
Travelling with non-divers	Operator offering scuba and snorkeling	Compatible schedules and boat arrangements

For beginners, instructor support is particularly important. Vietnam Active currently offers two Discover Scuba dives with a maximum of two participants per instructor. Nha Trang Sea Star describes a first dive progressing to a maximum depth of 6 metres and a second dive up to 12 metres.

Certified divers have greater flexibility, with sites selected according to certification level, recent experience and current conditions.

3. Best dive sites in Nha Trang

3.1 Hon Mun Marine Area

When it comes to scuba diving in Nha Trang, Hon Mun is often the first name that comes to mind. However, Hon Mun is not a single diving route. It is a large marine area with multiple locations featuring different terrain and depths.

PADI notes that the diving environment around Nha Trang includes coral reefs, walls, sandy bottoms and underwater rock formations. One site in the Hon Mun area has a recorded depth of up to 40 m.

This depth does not apply to every trip. Beginners will not be taken down to such depths.

What you should ask the dive centre is which area of Hon Mun is expected to be used that day, approximately how deep it will be and whether it is suitable for your experience level.

The entrance fees have also changed. Under Khánh Hòa's Resolution 02/2025/NQ-HĐND, the current fee for the Hon Mun route is VND 10,000 per person per trip, while the inter-island route is VND 40,000. These fees do not include accident insurance.

Some older articles still mention a VND 60,000 diving fee, which can easily cause confusion. When booking a tour, ask the operator whether entrance fees, port fees and other related charges are already included in the price.

3.2 Moray Beach

Moray Beach combines reef areas with sandy sections and is often associated with slower reef exploration rather than large marine-animal encounters.

For photographers and divers interested in smaller species, this can be appealing because Nha Trang is known for reef fish, nudibranchs and other small tropical marine life.

Beginners should still ask about planned depth, visibility and instructor supervision because suitability varies with daily conditions.

3.3 Madonna Rock

Madonna Rock is another established name in local itineraries and is listed by PADI Adventures for activities including Discover Scuba Diving and Open Water training.

Its rocky underwater landscape offers a different experience from a simple coral garden.

However, passages, deeper areas and more complex terrain should only be approached according to certification, buoyancy skills and instructor guidance.

3.4 Hon Tam, Hon Mot and Dam Bay

Hon Tam, Hon Mot and Dam Bay regularly appear as alternative destinations in current operator schedules.

Vietnam Active currently lists Hon Tam and Dam Bay among its diving areas, while Nha Trang Sea Star states that trips may use Madonna Rock, Dam Bay–Hon Tre, Hon Mot or Hon Tam depending on wind conditions.

This flexibility is useful because a responsible operator should prioritise sea conditions and diver ability rather than guarantee a famous destination regardless of weather.

When booking, ask whether the advertised site is guaranteed or simply the intended destination.

4. Beginner diving, fun dives and certification

First-time diving

You do not need an existing scuba certification to join a supervised Discover or Try Scuba programme.

The experience normally begins with equipment instructions, safety information and basic underwater skills before progressing to a supervised reef dive.

Current published examples include:

• Vietnam Active: USD 80 for two dives at two sites, with a maximum of two participants per instructor.
• Nha Trang Sea Star: USD 75, with a first dive progressing to 6 metres and a second dive up to 12 metres.

Inclusions can cover equipment, instructors, transfers, food, entrance fees and insurance, but packages differ.

Medical requirements can also vary, so check your operator's questionnaire before booking.

Certified fun diving

Certified divers can join guided recreational dives without repeating beginner training.

Current publicly listed prices include:

• Vietnam Active: USD 70 for two dives or USD 90 for three dives.
• Nha Trang Diving Club: USD 65 for its certified-diver trip.
• Nha Trang Sea Star: Nha Trang Sea Star: USD 65 for fun diving and USD 72 for a refresher option.

A difference of a few USD does not say much if the group size, equipment quality or other inclusions vary.

A group of three with a dedicated instructor will provide a very different experience from a larger group, even if the prices are nearly the same.

Getting certified

If you want to take a structured course during your trip, Nha Trang also offers Open Water courses.

Nha Trang Diving Club currently lists its SSI Open Water Diver course at USD 300. Nha Trang Sea Star offers an SSI course for beginners from USD 320, lasting three days.

A PADI Open Water programme on PADI Adventures also lasts approximately three days, including confined-water training and four open-water dives.

After completing Open Water, divers are generally allowed to participate in recreational diving to a maximum depth of 18 m within the scope of their certification.

5. How much does scuba diving in Nha Trang cost?

As of August 2026, a realistic budget is:

Experience	Published price example
Discover/Try Scuba	USD 75–80
Certified two-dive trip	Around USD 65–70
Three-dive certified trip	From around USD 90
Refresher	Around USD 72
Open Water certification	Around USD 72

Check whether equipment, a dive computer, meals, transfers, insurance and entrance fees are already included in the price. A package that is USD 10 cheaper but excludes a few items may end up costing more when you make the final payment.

6. How to choose a dive centre

Choose the operator according to your experience and the level of support you need.

Start by checking recognised training affiliations and clear programme information. PADI currently lists affiliated centres in Nha Trang, while Nha Trang Diving Club identifies itself as an SSI-certified centre.

Before booking, ask about the instructor-to-guest ratio, equipment condition, emergency oxygen, insurance, medical screening and policies for changing sites when sea conditions are poor.

Language support is also quite important for first-time divers. You need to clearly understand the safety instructions before entering the water, rather than trying to guess through gestures.

Three operators currently publish relatively clear pricing information:

Centre	Current published price
Vietnam Active	USD 80 for beginners, USD 70/90 for 2/3 dives
Nha Trang Diving Club	USD 75 Try Scuba, USD 65 diving trip, USD 300 SSI Open Water
Nha Trang Sea Star	USD 75 introductory experience, USD 65 diving trip, SSI course from USD 320

Vietnam Active also states that certified-diver groups have a maximum of three people, while beginner groups have a maximum of two people per instructor.

This detail is more worth considering than a small difference in price.

7. What time of year is more favourable for scuba diving in Nha Trang?

There is no month that guarantees consistently clear water or calm seas.

Nha Trang Diving Club currently prefers around April to October. Within the same month, today's conditions can still be very different from those three days later.

Time	Typical conditions
Tháng 4–8	Easier to schedule, although visibility still varies from day to day
Tháng 9–10	Diving is still possible; it is advisable to monitor the weather closer to the trip
Giai đoạn mưa hoặc biển động	Visibility is more likely to decrease or the dive site may need to be changed

If diving is an activity you really want to experience, do not schedule it for your final day. Leaving one or two days as a buffer makes it easier to manage if the boat has to be postponed due to poor sea conditions.

8. What can you see underwater in Nha Trang?

Do not visit Nha Trang expecting to definitely encounter large fish.

The strength of these waters lies more in coral reefs and smaller marine life. PADI records hard corals, soft corals, reef fish and nudibranchs, along with some sightings of rays and cuttlefish

People who enjoy close observation or photographing small marine life can often find plenty of interesting subjects in this type of environment.

Beginners also do not need to go very deep to see fish. Many marine creatures live around reefs at more accessible depths.

Do not choose a tour that guarantees encounters with a specific animal. When entering the water, do not touch coral, feed marine life or chase them for photographs.

9. What time does a typical diving day start?

Most diving trips in Nha Trang start fairly early and take around half a day.

Vietnam Active currently describes hotel pickup at around 7:30. Guests then board the boat, travel into the bay, complete two dives, take a surface interval, have lunch and return to the harbour at around 14:00.

Sea Star has a similar schedule. Guests are picked up around 7:00-7:30, the boat leaves the harbour at 8:00 and returns to the hotel at around 13:30.

Time underwater is only one part of the trip.

You also need to prepare equipment, listen to briefings, travel by boat and take a surface interval between the two dives. Therefore, do not schedule another activity too close to the end of the tour.

Swimwear, sun protection and personal items should be prepared the night before. If you are taking medication or have a health condition, inform the centre before the departure date.

10. Should you choose scuba diving or snorkelling?

If you want to stay underwater longer and observe reefs at greater depths, scuba diving is more suitable.

Snorkelling is more accessible. You do not need to learn many skills, preparation time is shorter and it is suitable for groups with children or people who do not want to go deep.

Sea Star currently lists a snorkelling trip at USD 32 per person, including equipment, transfers, drinks, lunch and entrance fees.

A group with divers and people who only want to snorkel can still travel together, but ask in advance whether the two programmes use the same boat.

Similar itineraries do not necessarily mean they will depart together.

11. Diving safety and waiting time before a flight

Do not skip the medical questionnaire just because you feel healthy.

Scuba diving causes pressure changes that the body needs to adapt to. Provide accurate information about your health condition and medications, and follow your instructor's guidance.

When underwater, stay within a depth that is appropriate for your certification and skills. If you feel unwell, tell someone immediately. You do not need to complete a dive site simply because you have already paid for the tour.

After diving, your body also needs time before flying.

• 12 hours after a single no-decompression dive.
• 18 hours after multiple dives in one day or multiple consecutive days.
• 24 hours or more after dives requiring mandatory decompression stops.

Having additional rest time is still better. If your return flight is the next morning, do not schedule a late dive the day before.

12. Where to stay if you want to go scuba diving in Nha Trang?

Staying in the central area makes a diving day simpler because many centres offer hotel pickup and then transfer guests to the harbour.

TUI BLUE Nha Trang is a comfortable 5-star hotel at 18 Tran Hung Dao, around 350 m from the beach and approximately 30 km from Cam Ranh International Airport.

After finishing a morning dive trip, you can return to rest and then continue exploring central Nha Trang in the afternoon or evening without needing another long journey.

At the hotel, Xanh Ciao Restaurant at TUI BLUE Nha Trang serves Mediterranean cuisine combined with some traditional Nha Trang specialities and Vietnamese dishes. Guests can also use the private beach area from 8:00 to 16:00. The number of umbrellas and loungers available there is limited.

TUI BLUE Nha Trang does not organise scuba diving directly. You still need to book this activity with a diving specialist and confirm in advance whether they offer hotel pickup.

13. Frequently asked questions about scuba diving in Nha Trang

Can people who have never dived before participate?

Yes. Discover Scuba and Try Scuba are designed for people without certification. The instructor will teach basic skills and closely supervise participants throughout their time underwater.

How much does a diving trip in Nha Trang cost?

Programmes for beginners currently cost around USD 75-80. For certified divers, a two-dive trip generally starts at around USD 65-70.

How much does a diving trip in Nha Trang cost?

Hon Mun is the best-known area, but it is not always the most suitable choice on a given day. Madonna Rock, Dam Bay, Hon Tam and Hon Mot are also included in the itineraries of dive centres.

When should you go scuba diving?

Around April to October is currently the period preferred by Nha Trang Diving Club. Even so, you should check sea conditions close to your trip rather than relying only on the month.

Is certification mandatory?

No, if you join a beginner programme with instructor supervision. Certification is required when booking a recreational diving trip for trained divers.

14. Before confirming your dive trip

There are a few questions worth asking the centre before transferring payment.

• How many people will be with one instructor?
• Does the price include equipment, insurance and marine fees?
• Can the dive site change if the weather is poor?
• Where will guests be picked up and approximately what time will they return?

If the answers are clear, it will be much easier to know whether the trip suits you than simply looking at the island name or price.

And if this is your first time scuba diving, do not set a goal of going as deep as possible. A comfortable dive where you can control your breathing and have time to observe the coral reefs will be more memorable than trying to chase depth.
