The teams take off from their Pit Stop at a rice paddy and receive a clue instructing them to travel by taxi twenty miles to the Ly Thai To Garden in Hanoi, Vietnam. The teams receive 588,000 Vietnamese dong, but must first pick it up, as it is not included with the clue. At the Garden, the teams receive an auditory clue that eventually directs them to the Hydrofoil Harbor in Ben Xe Bai Chay. There, the teams face a Roadblock which requires one member of each team to make a steep climb. After completing the task, the teams take a motorboat 1.2 miles to the Song Sot Cave and search for the next clue. Its a Detour that requires them to choose between Over (delivering supplies) or Under (hauling oysters.) Difficulty in navigating the boats and problems with wind lead to a suspenseful finish.
