If you are looking for a break from the crowded beaches of Nha Trang, Diep Son island is the place to go. It is famous for a unique underwater sandbar that lets you walk from one islet to another in the middle of the ocean. In this guide, we will give you the practical facts on how to get to Diep Son island, the actual costs, and what you can really expect when you get there.
Is Diep Son island worth visiting?
Yes, definitely. If you are looking for a break from the crowded tourist spots in Nha Trang, Diep Son island is absolutely worth a visit. It offers a raw, natural beauty that you won’t find at the more developed beaches.
Here are the main reasons why you should add it to your trip:
- The unique underwater sandbar: This is the island’s most famous feature. It is the only place in Vietnam where you can walk on a 700 meter white sand path connecting three small islets in the middle of the ocean.
- Crystal-clear and calm water: The sea around Diep Son island is very shallow and transparent. It’s perfect for swimming, wading and taking incredible photos without the big waves of the open ocean.
- A peaceful escape: Unlike the busy mainland, there are no noisy jet skis, loud music, or pushy vendors here. It’s a quiet, rustic paradise where you can truly relax.
- Authentic local vibe: Because the island is home to a small fishing community, you get to experience the simple, honest lifestyle of the locals who have lived here for generations.
- Budget-friendly: There are no expensive entrance fees or high-end resort prices. It is a very affordable day trip for those who love exploring hidden gems.
Where is Diep Son island located?
Diep Son island Nha Trang is located in Van Phong Bay, Khanh Hoa Province. It is about 60 kilometers north of Nha Trang city center.
Specifically, the island is part of the Van Thanh Commune in Van Ninh District. It is actually a cluster of three small islets (Bip, Giua and Duoi), connected by the famous underwater sandbars.
To reach Diep Son island, you first need to travel from Nha Trang to Van Gia Port, which is the main gateway for boats and speedboats heading to the island. Its remote location away from the city is exactly what keeps the water so clear and the atmosphere so peaceful.
How to get to Diep Son island
To reach Diep Son island, your journey will consist of two main parts: traveling from Nha Trang to Van Gia Port and then taking a boat to the island. Here are the best ways to handle each step:
Step 1: From Nha Trang to Van Gia Port (60 km)
Van Gia Port is the main gateway to the island. You have three main options for this land leg:
Private car or taxi: The most comfortable and fastest way. It takes about 1 hour and 15 minutes. This is ideal if you are traveling in a group or with family.
- Price: $30 – $45 (700,000 – 1,000,000 VND) for a round-trip (4 to 7-seater car).
Motorbike: If you love adventure, you can rent a bike in Nha Trang and drive north along Highway 1A. It’s a straightforward route with beautiful coastal views.
- Price: $5 – $8 (120,000 – 200,000 VND) per day for rental and fuel.
Local bus: This is the cheapest option. You can take bus number 01 (Nha Trang – Van Gia) from the city center. However, it takes longer (about 2 hours) and has many stops.
- Price: $1.50 (35,000 VND) per ticket. It takes about 2 hours due to frequent stops.
Step 2: From Van Gia Port to Diep Son island
Once you arrive at the port, you can choose between two types of water transport:
Speedboat (Cano cao toc): This is the most popular choice for tourists. It only takes about 15 minutes to reach the island. Speedboats usually run throughout the morning when there are enough passengers.
- Price: $8 – $10 (200,000 – 250,000 VND) for a round-trip ticket.
- Note: Boats usually run from 8:30 AM to 11:00 AM and depart when there are enough passengers (8-10 people).
Local wooden boat: This is a slower, more traditional experience. It takes about 40 – 50 minutes. These boats usually have fixed schedules (often departing around 9:00 AM and returning at 1:00 PM), so you must be on time.
- Price: $2 – $4 (50,000 – 100,000 VND) for a one-way trip.
- Note: These have fixed schedules, typically departing at 9:00 AM and returning at 1:00 PM. They are budget-friendly but can be shaky if you get seasick easily.
Because boat schedules can change depending on the weather and the number of tourists, it is always a good idea to arrive at the port before 9:00 AM to ensure you have plenty of time to explore Diep Son island.
Best things to do on Diep Son island
While Diep Son island Vietnam is small and quiet, it offers several unique activities that you won’t find at other tourist beaches in Nha Trang. Here are the top things you should not miss:
Walk on the Iconic Underwater Sandbar
This is the “signature” experience of Diep Son. When the tide is low, a white sand path emerges from the turquoise sea, connecting the three islets over a distance of about 700 meters.
The experience: Walking on this narrow path with the crystal – clear ocean on both sides is a one-of-a-kind feeling – like you are literally walking on water.
Swim in the crystal-clear turquoise water
The sea around Diep Son is incredibly calm, shallow, and transparent. Because the island is tucked away in Van Phong Bay, there are almost no big waves, making it an ideal “natural swimming pool”.
You can see the sandy bottom and small schools of fish clearly through the water. It is extremely safe for children and those who are not strong swimmers.
Go Kayaking or SUP Boarding
If you want to explore the hidden corners of the three islets at your own pace, renting a kayak or a Stand-Up Paddleboard (SUP) is a fantastic idea.
The experience: The water is so still that paddling feels effortless. You can move between the islets, take stunning “Aesthetic” photos from above, and find quiet spots far away from other tourists.
Visit the local fishing village
Take a short walk away from the main beach to see the simple houses and the daily life of the island’s residents. Diep Son is home to only about 80 households. You’ll see fishermen mending their nets, children playing by the shore, and a very peaceful, non-commercial side of Vietnam. It’s a great place to slow down and appreciate the “slow life”.
Feast on fresh local seafood
No trip to Diep Son is complete without tasting the “gifts from the ocean”. There are a few small stalls and local eateries right on the beach serving seafood caught daily by the islanders.
Must-try dishes: Grilled squid, steamed snails with lemongrass, and the famous Diep Son Fish Pancake (Banh Xeo Ca). The prices are very reasonable compared to the main restaurants in Nha Trang city and the freshness is unbeatable.
Check-in at the “Bridge of Love” (Ngoc Trai Bridge)
Near the pier, you’ll find a long wooden bridge stretching out into the sea, often called the “Bridge of Love”. This is the perfect spot for panoramic photos of the bay. Many couples come here to catch the sunset or simply enjoy the sea breeze before heading back to the mainland.
Diep Son island tour: Should you book one?
Deciding whether to visit Diep Son Vietnam on your own or join a guided tour depends on your travel style and how much planning you want to do. Here is a quick comparison to help you choose:
- Go on your own if: You are an experienced traveler, comfortable riding a motorbike for 60km and savvy at reading a Diep Son island map to navigate the remote roads of Van Ninh district. You’ll also need to manage local boat schedules, which can be unpredictable.
- Book a tour if: You want a stress-free day. A tour handles everything – private car pickup from your hotel in Nha Trang, speedboat tickets, a local seafood lunch and most importantly, a guide who knows the exact tide schedule so you don’t miss the underwater path.
Most visitors find that booking a tour is the most efficient way to see the island in one day. Here is why:
- Time saving: You won’t waste time waiting at the port for a boat to fill up.
- All-inclusive: Lunch, snorkeling gear and transport are usually included in one price.
- Safety & logistics: The tour operator monitors the sea conditions and tide charts daily to ensure you arrive when the sandbar is at its most beautiful.

Best time to visit Diep Son island Vietnam
To see the famous underwater sandbar at its best, timing is everything. Because the path is created by the tides, you need to plan your trip around both the weather and the lunar calendar.
- The best month is December to August. The ideal time to visit Diep Son Vietnam is during the dry season, specifically from December to August.
- December to June: The weather is sunny, the air is pleasant, and the sea is very calm. This makes the boat ride from the mainland much smoother, especially for those who get seasick.
- July to August: It is still sunny and great for swimming, but it can get quite hot. Make sure to bring plenty of sunscreen and water.
- September to November: This is the rainy season in Khanh Hoa. It’s best to avoid these months as storms or heavy rain can make boat travel dangerous and hide the sandbar completely.
Even in the best months, the sandbar isn’t visible all day long. Its appearance depends on the lunar cycle:
- From the 1st to the 15th of the lunar month: The tide usually recedes in the afternoon.
- From the 15th to the end of the lunar month: The tide typically recedes in the morning.
Tip: To see the path clearly and walk on dry sand, you should aim to arrive during low tide. Most local tour guides and boat operators track these schedules daily, so don’t hesitate to ask them for the exact “magic hour” before you depart.
Where to stay near Diep Son island
Because Diep Son island Nha Trang is a small, quiet community, there are no luxury hotels or resorts directly on the island. Most travelers visit for a day trip and return to the mainland. However, depending on your style, you have a few options:
- Return to Nha Trang (Most Popular): Since the island is only about 1.5 to 2 hours away, most people choose to stay in Nha Trang city. You can enjoy the island during the day and head back to the city for a comfortable hotel and a wide variety of dinner options.
- Stay in Van Gia Town: If you want to catch the earliest boat to the island or arrive late from the island, you can stay in a local guesthouse or a 2-star hotel in Van Gia (near the port). Options like Le Tung Hotel or CocoSea Hotel are clean, basic and very affordable.
- Doc Let Beach Area: Located about 20 – 30 minutes from the port, Doc Let has several beautiful beachfront resorts like Pax Ana Doc Let or TTC Resort. This is a great middle-ground if you want a relaxing resort vibe closer to the island than Nha Trang.
- Whale Island Resort: For a more secluded and eco-friendly experience, this resort is located further into Van Phong Bay. It’s a bit of a detour but offers a stunning, quiet stay in nature.
- Camping on the Island: For true adventurers, you can bring your own tent or rent one from the locals to camp on the beach. There is nothing quite like waking up to the sunrise on a quiet island, but keep in mind that facilities (toilets and electricity) are extremely limited.
Food and local experience
Visiting Diep Son island is not just about the sandbar; it is also a chance to taste the fresh flavors of Van Phong Bay and see a simpler side of Vietnamese life. Since the island is rustic, the food is fresh and very affordable.
Must try local food:
Because this is a fishing community, the seafood is as fresh as it gets. You won’t find fancy menus here, but you will find delicious local stalls near the pier:
- Fresh seafood: You can choose live fish, flower crabs, squid, or sea snails right from the baskets of local fishermen. They will grill or steam them for you on the spot.
- Banh xeo (Vietnamese savory crepes): The Diep Son version of Banh Xeo is usually filled with small, sweet squid or shrimp caught that morning. It’s crispy, hot and perfect for a quick lunch.
- Grilled fish: Simple but packed with flavor, often served with local herbs and a spicy dipping sauce.
Life on Diep Son island moves at a different pace. To truly enjoy the local vibe, try these small experiences:
- Visit the local market: If you arrive early in the morning, head to the small market near the village. It’s where locals gather to trade their daily catch and chat.
- Watch the sunset: If you stay late enough to catch the last boat, the sunset over the bay is spectacular. The water turns golden, and the fishing boats heading out for the night create a beautiful silhouette.
Tip: Most food stalls only accept cash and there are no ATMs on the island. Make sure to bring enough small bills to enjoy all the local treats!
Travel tips for visiting Diep Son island
To make sure your trip to Diep Son island tour is smooth and enjoyable, here are some practical tips to keep in mind before you head out:
- Check the tide schedule in advance: This is the most important tip. The sandbar is only visible during low tide. If you arrive at high tide, the path will be underwater. Ask your boat operator or hotel for the day’s tide chart before you leave Nha Trang.
- Bring plenty of sunscreen and a hat: There is very little shade on the sandbar and around the island. The sun in Van Phong Bay can be very intense, especially between 10:00 AM and 2:00 PM.
- Carry enough cash: There are no ATMs or banks on Diep Son island. You will need cash for boat tickets, local food and small souvenirs.
- Pack a power bank: Electricity on the island is limited and mostly comes from generators. If you plan on taking a lot of photos and videos, make sure your phone is fully charged and bring a portable charger.
- Keep the island clean: Diep Son island is a beautiful, rustic place. Please be a responsible traveler by taking your trash back to the mainland or disposing of it in designated bins to help protect the local environment.
- Wear waterproof shoes: Since you will be walking on a sandbar that might still have a little water, flip-flops or water shoes are much better than sneakers.
- Bring a basic medical kit: There are no pharmacies or large clinics on the island. It’s a good idea to bring some bandages, antiseptic and motion sickness medicine for the boat ride.
Diep Son island is truly a hidden gem that offers a rare blend of adventure and tranquility. From the adrenaline rush of walking on the unique underwater sandbar to the simple joy of enjoying fresh seafood by the shore, this island promises an experience that stays with you long after you leave. While its beauty remains raw and rustic, planning a visit requires a bit of timing and local knowledge to catch the tides just right.
