Diep Son Island Guide: Getting There, Tides & Best Time
Plan a Diep Son Island trip from Nha Trang: Van Gia boat access, low-tide sand path, best season, costs and mistakes to avoid.
On this page
Last updated November 2026: Diep Son island is a small cluster of islets in Van Phong Bay, in the Van Ninh area north of Nha Trang. You reach it by road to Van Gia, then a short boat ride. Its sand path between islets is walkable only at low tide, so an early start in the dry season works best.

Diep Son Island at a Glance
Diep Son lies in Van Phong Bay, in Khanh Hoa province. Three islets form the cluster: Hon Bip, Hon Giua and Hon Duoc. A sand path joins them when the tide is low. Reported distance from central Nha Trang to Van Gia pier is about 60 km, followed by a boat ride of roughly 10 to 40 minutes. Aim for December to April and a departure around 6 to 7 am.
- Base: Nha Trang, then north on National Highway 1A to Van Gia village
- Crossing: Van Gia pier to the islets by speedboat or small local boat
- Main attraction: sand path of about 800 m, usable only at low tide
- Best window: December to April, morning departure
- Facilities: basic, with limited food, water and power on the islets
Where Diep Son Island Is and What You'll See
Van Ninh district holds Van Gia, the mainland village where boats leave. Offshore, Hon Bip is the largest islet and the one tour groups head for. Its restaurant fills with day-trippers around midday. Hon Giua, the middle islet, is rocky underfoot, and local women mend fishing nets there. Quieter stops can have a closed restaurant, an empty beach and an abandoned house. Ngoc Trai pier is reported at 300 m long and works as a photo spot. Kayaking is a common add-on at the beach. Island households live from fishing, so expect basic services. Fresh water and electricity are not always available.
How to Get to Diep Son Island From Nha Trang
Road travel covers the first leg. Head north out of Nha Trang on National Highway 1A, turn right toward Van Gia village, then follow Tran Hung Dao Street to the pier. Prices and hours checked November 2026. Distances differ between accounts: about 60 km, or 60–70 km and 1.5–2 hours by car, with one outlier near 120 km. Plan on two hours and treat anything faster as a bonus. Local bus number 1 is reported to reach Van Gia in under an hour, and the pier is about a 15-minute walk from the bus stop. Prefer a packaged day? Compare a four-island boat tour, which is a separate trip from this one.
| Option | Reported cost | Reported time | Trade-off | Best for |
|---|---|---|---|---|
| Local bus 1 | Cheap, fare not confirmed | Under 1 hour | Fixed route, short walk to pier | Budget solo travelers |
| Bus or shuttle | ₫100,000–150,000 per person | Morning departures | Check it stops near Van Gia pier | Budget travelers |
| Private car or taxi | ₫1,000,000–1,500,000 for a 4-seat car | 1.5–2 hours | Stops on the way, scarce at weekends | Families and groups |
| Motorbike | ₫150,000–200,000 per day | 1.5–2 hours | Freedom, but tiring with luggage | Experienced riders |
Van Gia Pier and Boats: Tickets, Timing, Which Islet
Speedboats cross in about 15–20 minutes, and round-trip tickets run ₫200,000–300,000 per person. Small local boats take 30–40 minutes. Chartering a whole boat costs about ₫500,000–700,000 per trip. One 2019 traveler paid ₫100,000 each way and had to buy a return ticket. Schedules are not fixed, and boats may wait for enough passengers. Get to the pier by 7 am. A 2 pm arrival in that same account meant no boat that day. Tell the ticket seller you want Hon Bip, because the islands have more than one pier. That traveler landed on an empty islet with a closed restaurant. Buy a return only from the operator serving your islet, since a ticket from another boat company was refused at Hon Bip. The last boat back was reported at about 1:30 pm.
The Sand Path and Tides
Timing decides whether you see the sand path at all. It stretches about 800 m between islets and is passable only at low tide. Look up a tide table for the Khanh Hoa coast before you book a boat. Choose a day with low tide in the morning, so you cross before the water rises. One 2019 visitor reached Hon Bip around 12:30 pm and waded knee-deep because the bar was unclear. Rocks, not sand, cover much of the middle islet, so wear shoes with grip. If the tide is wrong, spend the wait on the beach, kayaking, or over lunch on Hon Bip. Never start a crossing while the water is rising, and keep your bag high.
A late crossing leaves little slack, since one visitor reached Hon Bip around 12:30 pm and the last return boat was reported near 1:30 pm.
Best Time to Visit Diep Son Island
Plan for December to April, when the weather is dry and the sea is calm and clear. Some guides stretch the season to August, so May to August depends on the forecast. May to November is flagged as stormy, with strong waves, delays and cancelled boats. Skip the trip whenever the sea is rough. Morning departures between 7 and 9 am avoid midday heat and leave time before the tide rises. Read the marine forecast the evening before and again at dawn.
Sample Day-Trip Plan and Time Budget
Times below are indicative. Your tide table sets the real schedule, and boats leave when they fill.
- 6:00–7:00 am: leave Nha Trang by car, motorbike or shuttle (1.5–2 hours by road)
- About 8:00 am: buy tickets for Hon Bip at Van Gia pier and confirm the return boat
- 8:30–9:00 am: cross by speedboat (15–20 minutes) or small boat (30–40 minutes)
- Late morning: walk the sand path at low tide
- Midday: lunch at the Hon Bip restaurant, then swim or kayak
- Before the last boat (reported near 1:30 pm): head back to Van Gia
- Afternoon: return to Nha Trang by bus or car
Costs and What to Budget
Transport and the boat make up nearly all of the spend. Four people sharing a car at ₫1,000,000–1,500,000 pay ₫250,000–375,000 each. Chartering a small boat at ₫500,000–700,000 splits to ₫125,000–175,000 each, which undercuts individual speedboat tickets but takes longer. Lunch on Hon Bip comes on top, and the 2019 ₫100,000 one-way fare shows prices have moved. Sugarcane juice in Van Gia cost under half the Nha Trang price in that account.
| Scenario (4 people) | Car share | Boat share | Total per person |
|---|---|---|---|
| Car plus speedboat tickets | ₫250,000–375,000 | ₫200,000–300,000 | ₫450,000–675,000 |
| Car plus chartered small boat | ₫250,000–375,000 | ₫125,000–175,000 | ₫375,000–550,000 |
Staying Overnight: Island vs Van Gia
Overnight options are thin. One small bungalow resort and a camping option are reported on the islands. Fresh water and power are not guaranteed there. Van Gia has hotels within a five-minute walk of the pier, though one traveler found prices high and quality uneven. About ₫300,000 was paid after bargaining in 2019. Van Gia offers little beyond a sunset near the Tran Hung Dao Bridge, where locals sit with sugarcane juice. Litter collects on the small beach nearby. Our verdict: treat Diep Son as a day trip from Nha Trang. Sleep in Van Gia only if reaching the pier by 7 am matters.
Get to the pier by 7 am. Hotels in Van Gia sit within a five-minute walk of it, so an overnight stay can make that start easy.
Is Diep Son Worth It? Compared With Other Nha Trang Islands
Diep Son costs a long road leg and a tide-dependent walk. In return you get far fewer crowds away from Hon Bip. For a snorkeling-led day, weigh Hon Mun for snorkeling against it. For a shorter, closer-in outing, look at an easier day on Hon Tam. Each has its own logistics. A wider range of island day trips from Nha Trang helps you pick by crowds, distance and sea conditions. Diep Son suits travelers who accept a 6 am start for a quieter, rougher-edged day.
Mistakes to Avoid and Safety Checklist
Most failed trips trace back to a few avoidable choices. Late departure costs the most, as a 2 pm arrival at Van Gia showed. Wear a life jacket on every crossing and keep electronics in a waterproof bag. Watch for jellyfish and sea urchins while swimming, and carry your rubbish off the islets.
- Leaving Nha Trang late and missing the morning boat
- Assuming a ticket works at every pier or on every boat
- Skipping food and water, since islet supplies are limited
- Ignoring the tide table before booking
- Traveling in the rough-sea months of May to November
- Wearing sandals on rocky stretches of the middle islet
- Forgetting sunscreen, a hat and a power bank
