Sixteen islands, some of the clearest water in Vietnam, and a past that demands to be understood. Con Dao is the rare destination that moves you twice: once with its beauty, once with its history.

Con Dao is an archipelago of 16 islands where extraordinary natural beauty sits alongside a difficult past. For over a century the main island, Con Son, served as a prison island, first under French colonial rule from 1862 and later through the war years. Today the old cell blocks stand as museums, the forests have reclaimed the hills, and the surrounding waters hold some of the clearest diving in Vietnam.
The prison complex is the reason many Vietnamese visitors come, and it deserves half a day of any itinerary. The Phu Hai and Phu Son prisons, the tiger cages with their small sun baked cells, and the museum tell the story of the thousands held here through photographs, artifacts and the buildings themselves. Go with a guide if you can: the context turns stone walls into something you will not forget.
What surprises first time visitors is how the island refuses to be defined by its past. Beyond the town, Con Dao is all forested hills, empty roads and beaches where the only footprints are your own. The two stories coexist without competing, and most travelers leave moved by both.
Many visitors also walk through Hang Duong cemetery at dusk, where memorials honor those who died on the island, including the young revolutionary Vo Thi Sau. Vietnamese tour groups often visit in the evening with incense and flowers. Go quietly and dress respectfully: for many, this is a place of pilgrimage.
The sea is Con Dao great gift. Dam Trau Beach on the northeast coast offers white sand, old forest and coral you can snorkel straight from shore. The town beaches are calm and swimmable, while the wilder west coast rewards explorers with total solitude and dramatic sunsets.
Divers rate Con Dao among the best sites in Vietnam. The marine park protects coral reefs, rays, turtles and occasional dugongs, with visibility often excellent from March to September. Several dive shops in town run daily trips to sites around the outer islands, and snorkeling tours visit shallow reefs that rival anything in the region.
Hon Bay Canh, the second largest island, makes the best day trip: a ranger station beach, jungle trails and a turtle conservation center where you can learn about the nesting program before the night excursion. Boat tours from Con Son town combine it with snorkeling stops, usually departing around 8:00 and returning by 15:00.
From May to October, green sea turtles come ashore to nest on Hon Bay Canh island. Rangers run small group night excursions where you can watch a nesting female and, with luck, help release hatchlings into the surf. Numbers are limited and bookings go through the national park office, so arrange it as soon as you arrive.
The fast option is flying: direct flights from Tan Son Nhat take 45 to 50 minutes, with multiple departures daily, and fares start around 1,000,000 VND (about $40) one way when booked ahead. The small airport sits at the north of Con Son, a 15 minute ride from town.
Ferries suit travelers with time and sea legs. A direct high speed ferry runs from central Ho Chi Minh City in about 5 hours, with one way fares from 965,000 to 1,325,000 VND (about $39 to $53) depending on day and cabin class. The Vung Tau crossing takes 4 to 4.5 hours and the Soc Trang route from Tran De is the shortest sea leg at about 2.5 hours. All ferries cancel in rough weather, most often from November to February, so keep your plans flexible.
On the island, rent a motorbike for 150,000 to 200,000 VND a day and you can see everything. Roads are quiet and well kept, distances are short, and the coastal loop around Con Son is one of the prettiest rides in the country. Taxis and electric carts cover the town if you prefer not to ride.
Give Con Dao at least three days. Day one: settle in, rent your bike, swim at a town beach and walk the seafront at sunset. Day two: the prison complex in the morning, Dam Trau in the afternoon. Day three: a boat trip for snorkeling or diving, or the national park trek to Ong Dung beach through old forest.
Stay in town for restaurants and the night market, or splurge on a beach resort along Dat Doc if the budget allows. Guesthouses start around 400,000 VND a night, mid range hotels 800,000 to 1,500,000 VND. Seafood dominates menus: try the red grouper, moon crab and grilled squid fresh off the boats.
The dry months from December to April bring the calmest seas and easiest travel, though divers often prefer March to September for visibility. Bring reef safe sunscreen, motion sickness pills for the ferry, and a respectful mindset for the prison sites: modest dress and quiet voices, as many Vietnamese visitors come to pay respects.
Three full days covers the prisons, beaches and a boat trip. Four lets you slow down.
