A number of the resorts across Vietnam offer water-sports from the beach (including kayaking, sailing, jet-skis, boating) or you can enjoy the underwater action around Phu Quoc on a snorkelling or diving tour arranged via one of the boat companies or through your hotel. Diving is best from November to March and fun dives will cost around USD100 per person, whereas snorkelling is around USD35 per person.
For many Nha Trang is the best place to head for the quality of the diving. It has, however, become very busy with a lot of different dive shops too so it is worth considering the kind of experience you would like before choosing. Diving off the coast of Hoi An is a place for many to try out diving. It isn’t busy there and so makes the ideal place to stop off for an extra couple of nights and to explore the underwater world.
Con Dao is considered one of the best examples of marine conservation in the country. With over 340 species of Hard and Soft corals, teeming with a colourful array of marine life. Con Dao supports a high level of biodiversity and over 1,400 currently recorded marine species. With clear waters from February to July and visibility averaging 20-30 metres, Con Dao is an excellent place for diving and offers a unique opportunity to explore the amazing variety of underwater life. Explore the untouched and pristine corals, with a chance to see rays, turtles, giant barracuda, cobia, batfish and small bamboo sharks, as well as a whole host of tropical reef fish.
Phu Quoc is often the beach stop of choice and there are a lot of dive sites around. The major dive sites on the Phu Quoc are Dry island and Nudibranch Island where you will be able to spot a variety of marine animals, including cuttlefish, octopus, scorpion fish, damselfish, nudibranchs, and moray eels. The sea is calm around here and in the dry season you’ll have clear water and great visibility.
