Best Places to Dive in Vietnam

Vietnam has various coastal areas offering ideal conditions for recreational diving: warm waters, good visibility, and a rich marine biodiversity. Here are some of the best diving spots in the country:

Nha Trang

Located on Vietnam’s southern coast, Nha Trang is a popular diving destination due to its tourist infrastructure, specialised schools, and proximity to protected areas such as Hon Mun Island. Underwater, you can see hard and soft corals, nudibranchs, parrotfish, moray eels, and other tropical species. Besides diving, the city offers lively atmospheres, wide beaches, and facilities for solo travellers or groups.

Phu Quoc

In the south, near the Cambodian border, this island is famous for its green jungles and quiet beaches. Phu Quoc’s reefs host butterflyfish, groupers, seahorses, and giant starfish. The area is perfect for beginners and those seeking relaxed dives with good visibility and colourful marine life. It’s also ideal for combining diving with beach days, food tours, and motorbike trips around the island.

Cham Island (Hoi An)

A few kilometres from Hoi An, Cham Island is part of a marine reserve with over 200 coral species. The site is known for its rich marine ecosystem: turtles, pufferfish, and tropical fish schools accompany divers. It’s an excellent choice for those seeking a protected natural environment while enjoying Hoi An’s cultural charm on land.

Con Dao

This archipelago, located off the southern coast, is known for more remote and less crowded dives. The clear waters allow sightings of manta rays, bamboo sharks, and turtles that come to the area to nest. Con Dao is perfect for those seeking tranquil dives, away from general tourism, in one of the country’s best-preserved ecosystems.

Whale Island

Located north of Nha Trang, Whale Island is a small island surrounded by well-preserved reefs. Its name refers to the seasonal presence of whales and whale sharks in the area. While sightings are not guaranteed, the local biodiversity includes tropical fish, healthy corals, and some exciting encounters with pelagic species. It’s an ideal destination for divers wanting to disconnect and enjoy a more exclusive underwater environment.

Here, you can see soft corals, parrotfish, snappers, seahorses, and small species hiding among the rocks. Visibility is usually good during the dry season, and being close to the city makes it ideal for travellers with limited time or those wanting to combine urban tourism and nature.
