Scuba Diving and Snorkeling in Vietnam: Top 3 Amazing Spots

Scuba diving and snorkeling are becoming top favorite ways to enjoy the beauteous ocean splendor of Vietnam. Brimming with potential for further exploration, the most idyllic diving spots are scattered along the central coastline and the Southern tip of Vietnam.

Vietnam has a tropical climate suitable more for macro-diving so don’t expect to see pelagic sea creatures like large sharks, rays, and turtles. Highlights of the dives include smaller species, shimmering corals, nudibranch, and reef fish.

Vietnam Scuba Diving Essentials

Most of the good dive sites in Vietnam are in the waters surrounding islands — đảo or hòn in Vietnamese. For hassle-free and safety-guaranteed diving, it’s best to choose a PADI-certified dive center such as those we mention for each location. They also provide courses for PADI certification.

Nonetheless, there are a few things you should note for yourself if you already have diving experience:

  • Make sure with dive operators that your dive buddies on the same trip are at the same level;
  • Check dive-master to students ratio – the ideal is one to two;
  • Inspect your equipment: oxygen regulator, buoyancy compensator, dive computer, dive mask, scuba fins, wetsuit, and snorkel.

Nha Trang isn’t only the third-best surfing spot but also the number one scuba diving spot in Vietnam. The three key diving locations out of the five main islands are Hon Mun Island (Hòn Mun), Bamboo Island (Hòn Tre), and Whale Island (Hòn Ông).

Hon Mun Island is Vietnam’s first marine reserve and Bamboo Island has the popular Vinpearl Land Amusement Park.

Boat tours to these main islands include not only snorkeling stop-offs but also onboard fishing. You can also enjoy a seafood BBQ and take time out to visit fishing villages.

Another main one is Hon Tam Island (Hòn Tằm), but it’s only good for shallow snorkeling. It’s great for other watersports like windsurfing, paragliding, canoeing, and kayaking though.

Best Time for Scuba Diving in Nha Trang

The scuba diving and snorkeling season in Nha Trang begins in April. July to August is ideal but it’s also peak holiday months so it can get very crowded and prices may go up.

Earlier in the year is not so bad and it’s more than enough to get your PADI diving licenses. Watch out for the rainy and stormy season from October to mid-January. During these months you can do diving in Phu Quy or Phu Quoc Islands instead.
