Con Dao Island has a strong political and cultural history. Under the French, Con Dao was used as a major prison for opponents of French colonialism.

Con Dao National Park, one of the country's top six biodiversity hotspots for both land and sea, contains thousands of plant and animal species, and provides a range of eco-tourism options.

The island is home to playful black and brown squirrels, many species of native and migratory birds, and even endangered marine animals like the sea cow, green turtle and hawk's bill turtle.

According to the Sai Gon Travel Service Company (Saigontourist), in the wedding season this year Con Dao was one of the most popular honeymoon destinations for young couples.
