The Sea Turtles of Vietnam | A Rare Encounter in Phu Quoc’s Coral Reefs

For millions of years, sea turtles have quietly journeyed across the world’s oceans, undertaking some of nature’s most awe-inspiring migrations.
In Vietnam, they were once a common sight along coastal waters. Today, however, that image is fading—and in Phu Quoc, spotting a sea turtle in the wild has become an exceptionally rare and meaningful encounter

1. Sea Turtle Species in Vietnam

Vietnam is home to five known species of sea turtles:
– Green Turtle (Chelonia mydas)
– Hawksbill Turtle (Eretmochelys imbricata)
– Leatherback Turtle (Dermochelys coriacea)
– Loggerhead Turtle (Caretta caretta)
– Olive Ridley Turtle (Lepidochelys olivacea)

All five species are listed as threatened or endangered by the International Union for Conservation of Nature (IUCN), and are strictly protected under Vietnamese law.

2. Regions Where Sea Turtles Still Nest in Vietnam

Sea turtle populations in Vietnam have declined dramatically over the years. Yet, a few coastal and island regions remain vital nesting and feeding grounds:
– Con Dao (Ba Ria – Vung Tau): Vietnam’s most important nesting site, particularly for green turtles. According to Con Dao National Park data, from January 1 to April 15, 2024, 65 successful nests were recorded. Thirteen female turtles were tagged for tracking, and 3,374 hatchlings were safely released into the ocean under close supervision.


– Hon Cau (Binh Thuan): Once a notable nesting site, now rarely visited by turtles. The area is still home to coral reefs and a rich marine ecosystem.
– Hon Mun Marine Protected Area (Khanh Hoa): On October 4, 2024, a hawksbill turtle was recorded by a conservation officer’s bodycam—marking the first confirmed sighting in this area after many years.
– Quang Tri, Quang Nam, and Ninh Thuan: Some beaches in these provinces have historically served as nesting grounds, though recent records are extremely limited. Across these regions, conservation programs continue, including relocating eggs to safe hatcheries and releasing hatchlings into the sea—crucial efforts to sustain their life cycle.

3. Sea Turtles in Phu Quoc: A Fragile Presence

– In Phu Quoc, only two species have been documented: Hawksbill Turtle (Eretmochelys imbricata) & Green Turtle (Chelonia mydas)

Several local islets still bear names that reflect a past connection with turtles:
Hon Doi Moi (Hawksbill’s Island): Once a thriving feeding ground for hawksbills, near one of the island’s largest coral reefs.
– Chuong Vich Beach: Believed to have been a traditional nesting site for green turtles.

Sadly, unsustainable tourism, marine pollution, illegal fishing, and trawling have caused severe damage to turtle habitats in Phu Quoc.
Even during the breeding season (April–October), sightings are extremely rare, and no natural nesting activity has been recorded on the island in over a decade.
Notably, the local hawksbill population is now classified as Critically Endangered by the IUCN.

4. Small Signs of Hope

Amid these challenges, faint yet hopeful signs have emerged. Recently, OnBird recorded the presence of a hawksbill turtle at the North East Coral Reef, Phu Quoc—a fragile but powerful symbol of resilience.

According to OnBird’s observation:
– The breeding season for sea turtles spans from April to October.
From April 12 to May 4, 2025, five turtle sightings were reported, including one case where a pair was seen swimming together.
– At the North East Coral Reef—one of the most biodiverse reef systems in southern Phu Quoc—lucky visitors might witness a hawksbill gliding gracefully through the water during the early morning or late afternoon while snorkeling.

This rare reappearance serves as a vital reminder: Every action we take to protect the ocean helps pave the way for sea turtles to return and thrive.
