Diving in Con Dao is considered one of the best underwater experiences in Vietnam, offering pristine reefs, diverse marine life, and unique dive sites. Whether you are a beginner or an advanced diver, this guide will help you plan your perfect diving adventure in Con Dao.
Best time for diving in Con Dao
The high season for diving in Con Dao runs from March to September, coinciding with warm temperatures and mostly calm seas. Although this is also the rainy season (especially from July to September), the rain usually comes in short bursts during the afternoon or evening, leaving the mornings ideal for diving.
The low season spans November to February, when stronger winds create choppier waters. However, there are still opportunities to dive on sheltered dive sites during good weather spells. Thanks to the variety of dive locations around the islands, you can often find spots suitable for diving even during this period.
Con Dao’s underwater world
Con Dao’s underwater world is a hidden gem, offering some of the most pristine and diverse marine environments in Vietnam. Protected as part of Con Dao National Park, this archipelago boasts vibrant coral reefs with over 340 species, making it a haven for marine life and a paradise for divers. The reefs are home to a dazzling array of tropical fish, including parrotfish, clownfish, and angelfish, while larger pelagic species like barracudas and groupers occasionally glide through the deeper waters.
The underwater landscape is equally captivating, featuring dramatic drop-offs, underwater rock formations, and caves that provide shelter to countless marine creatures. Con Dao’s warm, clear waters with visibility exceeding 20 meters during the high season make it an ideal diving destination for both beginners and experienced divers.
What truly sets Con Dao apart is its ecological significance and unique marine species. The islands are one of the last havens for the endangered dugong in Vietnam, a rare and gentle marine mammal that divers might glimpse in the area. Con Dao is also famous for its green and hawksbill sea turtles, which use the islands’ beaches as crucial nesting sites. These majestic creatures are often spotted by divers around the reefs.
Adding to the allure is Vietnam’s only shipwreck dive site, where marine life such as scorpionfish, moray eels, and sponges have transformed the wreck into a thriving artificial reef. With its biodiversity, ecological importance, and pristine conditions, Con Dao offers a truly unparalleled underwater experience.

Flying after diving
When planning your trip to Con Dao, it’s important to account for the time needed between diving and flying to avoid decompression sickness. Divers should not ascend to a high altitude within 12 hours after a single dive or 18 hours after completing multiple dives. If possible, waiting a full 24 hours is the safest approach.
