You can choose from several transportation options depending on your preference. If you want flexibility and a chance to enjoy the coastal scenery, traveling by motorbike or private car is a great option. Motorbike rental typically costs around 120,000 – 180,000 VND per day, with fuel costing an additional 50,000 – 80,000 VND for the trip. For budget travelers, local buses running from Nha Trang to Van Gia are available, with ticket prices ranging from 30,000 – 50,000 VND per trip, though you should confirm the nearest stop to the wharf. Alternatively, taxis or private transfer services are more convenient for families or small groups, costing approximately 700,000 – 1,000,000 VND per one-way trip.

Leg 2: From Van Gia Wharf to Diep Son Island (approx. 5–10km by sea, 15 – 30 minutes)

From the wharf, you will continue your journey by boat or canoe. Wooden boats are the more budget-friendly option, costing around 50,000 – 100,000 VND per person per trip and taking about 30 minutes, though they may be slower and less comfortable. Speedboats (canoes), on the other hand, take only 15 – 25 minutes and offer a smoother ride. Shared canoe rides typically cost 150,000 – 300,000 VND per person, while private rentals range from 1,500,000 – 2,500,000 VND per trip depending on group size.

Overall, getting to Diep Son Island is relatively straightforward. However, it is recommended to start early in the morning so you can fully enjoy your visit and catch the best time when the tide recedes, revealing the iconic sandbar walkway across the sea.

Best time to visit Diep Son island

The best time to visit Diep Son Island depends not only on the weather but also on the tides, an essential factor that determines whether you can experience the famous walking path across the sea. To make the most of your trip, it’s important to consider both the season and the time of day, based on natural conditions and insights from local tourism operators.

Best time of the year

According to the climate characteristics of South Central Vietnam, the ideal time to visit the island is from December to June.

During this period, the weather is generally dry with minimal rainfall, and average temperatures range from 25–32°C, making it perfect for outdoor activities such as swimming, sightseeing, and island hopping.

The sea is relatively calm thanks to the sheltered location within Van Phong Bay, ensuring safer and more comfortable boat or canoe transfers, especially for those prone to seasickness. The period from March to June is often considered the “golden time” due to its stable weather, clear waters, and ideal lighting conditions, perfect for photography and sightseeing.

In contrast, the period from September to November is the rainy season in Khanh Hoa, when rough seas, strong winds, and prolonged rainfall may occur. According to local tour operations, trips to the island during this time are more likely to be delayed or canceled due to safety concerns.

Best time of the day 

According to marine tourism experts and local observations, the most important factor when visiting Diep Son Island is the tidal schedule. The sandbar connecting the three islands only appears during low tide, which typically occurs 1–2 times per day, but the exact timing varies. Based on tidal patterns:

• During the first half of the lunar month (days 1–15): low tide usually occurs in the afternoon
• During the second half of the lunar month: low tide typically occurs in the morning (around 6:00 AM – 10:00 AM)

According to our local tour guides, the best time to walk and take photos is when the tide has just receded, usually between 9:00 AM and 1:00 PM, when the sand path is clearly visible, the water has not yet risen, and the lighting is ideal.
