An off-the-beaten-track snorkeling destination 

Almost all snorkeling spots in Vietnam are located on the islands scattered along the country’s 3260km-long coastline.

Nha Trang is the most popular snorkeling area in Vietnam, with great snorkeling spots located just offshore, particularly in Hòn Mun Marine Protected Area, reachable with boat tours. It is considered that 350 coral species are found in Nha Trang waters. Just 50km north to Nha Trang is Hòn Ong (Whale Island). This small island is renowned for its shallow and calm waters found right off the beaches. Book a stay at Whale Island Resort to get some of Vietnam’s best shore snorkeling.

Côn Đảo, an idyllic archipelago of 16 mostly uninhabited islets just off the southern coast of the country, is also a great option. Protected by a National Park, this area offers some of the most pristine snorkeling spots in Vietnam, with a dozen of great sites around the islands. Côn Đảo, located some 80km off the mainland’s coast, have really clear waters and provide better snorkeling conditions than anywhere else in Vietnam.

Located in the far south of Vietnam, close to Cambodia, Phú Quốc is also a fantastic snorkeling destination. Although the underwater visibility can be an issue here during the rainy season, Phú Quốc boasts beautiful coral reefs and varied marine life. Take a boat tour to the An Thoi archipelago to snorkel Gam Ghi, Mong Tay and May Rut islands, the most popular snorkeling spots in the area.

Other exciting snorkeling hotspots in Vietnam are the Cù Lao Chàm Marine Park (a group of 8 small islands off the coast of Hoi An) and the shore of Núi Chúa National Park, a secluded coastal area some 60km south to Nha Trang.

Vietnam may not have the best underwater sightings opportunities compared to Thailand, Indonesia or the Philippines, but its marine life is quite varied. Some snorkeling spots are rich is soft and hard corals, sponges, clams and nudibranchs. In the reef areas, expect to see a range of tropical fish from butterflyfish and clownfish to moray eels and pufferfish. The luckiest may also spot sea turtles, sea horses or frogfish in some specific spots.
