The Guide to the Underwater World Diving in Con Dao
Imagine yourself suspended in warm, crystal-clear water, sunlight piercing the surface in shimmering columns, revealing an entirely different world below. It is a world of vibrant coral gardens, of schooling fish that move as one in a silent dance, and of gentle, ancient creatures gliding through the deep.
Welcome to the underwater world of Con Dao – one of Vietnam’s best-preserved marine ecosystems. This guide is your companion, created to take you on a journey through the spectacular dive sites, fascinating marine life, and the unique conditions that define this scuba diving paradise.

1. What Makes Con Dao’s Underwater World So Special?
- Protected by a National Park: Most dive sites are located within the strictly protected core zone of the Con Dao National Park. This ensures healthier reefs and a thriving, balanced ecosystem.
- Exceptional Biodiversity: Con Dao is home to over 340 species of coral and more than 1,700 marine species, creating a vivid and colorful natural tapestry.
- The “Home of Sea Turtles”: This is a critical nesting and feeding ground for two rare species of sea turtle: the Green Turtle and the Hawksbill Turtle. The chance of swimming alongside a turtle in Con Dao is higher than anywhere else in Vietnam.
- Ideal Diving Conditions (in season): From March to September, the seas around Con Dao are typically calm with excellent, clear visibility, creating perfect conditions for underwater exploration.
2. The Stars of the Ocean: Marine Life Highlights

This is what you can expect to witness when you dive with Amadive in Con Dao.
- Sea Turtles: Without a doubt, turtles are the icon of Con Dao’s waters. You can easily encounter Green Turtles peacefully grazing on seagrass or Hawksbill Turtles searching for food within coral crevices. Especially now (in August), it is the peak of the nesting season, making sightings highly likely!
- Healthy Coral Reefs: Explore vast “fields” of table coral and staghorn coral, interspersed with colorful bushes of soft coral. The health of the reefs here is a testament to effective conservation efforts.
- Massive Schools of Fish: Prepare to be awestruck as you swim through swirling schools of thousands of Yellow-striped Fusiliers, Snappers, or Chevron Barracuda, creating shimmering silver “fish storms.”
- Macro Paradise: For lovers of tiny critters, get your camera ready to hunt for colorful Nudibranchs, shrimps, crabs, and other small fish hiding amongst the corals.
