Spend your last day exploring the historical sites and indulging in relaxation. Start with a visit to the infamous Con Dao Prison, also known as the 'Tiger Cages.' Learn about the dark history of the prison and the Vietnamese struggle for independence. Next, visit Hang Duong Cemetery, a solemn memorial for the Vietnamese revolutionaries who lost their lives on the islands. Take a moment to pay your respects. In the afternoon, treat yourself to a rejuvenating spa session or a traditional Vietnamese massage. Alternatively, you can spend the day lounging on the beautiful An Hai Beach, enjoying the sun and the sea. End your trip with a delicious seafood dinner at one of the local restaurants, savoring the flavors of the Con Dao Islands.
