Khanh Hoa Province dive sites

The best diving conditions are from February to September, when seas are calm, visibility peaks at 20 meters or more, and water temperatures hover around 27 to 30 degrees Celsius. The rainy season from October to January can bring reduced visibility and rougher seas.

Absolutely. The shallow reef sections between 5 and 12 meters are ideal for newly certified divers and even discovery dives. Calm currents and warm water make it one of Vietnam's most accessible dive destinations. Deeper sections around 18 to 25 meters suit more experienced divers.

Hon Mun is approximately 10 km south of Nha Trang and is reached by a 30 to 45 minute speedboat ride. Most dive operators in Nha Trang organize daily trips that include equipment, guide services, and two or three dives per outing.

Whale Island, known locally as Hon Ong, is located approximately 80 kilometres north of Nha Trang. Access is by road to the Van Phong Bay area followed by a boat transfer of about 20 minutes to the island. The single resort on the island arranges transfers for its guests. Independent divers can arrange day trips through Nha Trang-based operators, though the long road journey makes overnight stays more practical. The island resort operates seasonally, typically from March to October.

Whale sharks visit the waters around Whale Island primarily from April to July, coinciding with krill aggregations in Van Phong Bay. The sightings are not daily occurrences but are regular enough during peak season to give reasonable odds over a multi-day stay. The island earned its name from these visits. Encounters are typically surface-based snorkelling or freediving, as the whale sharks tend to feed in the upper water column. Outside whale shark season, the reef diving remains worthwhile.
