I Know Phil, Little Ol' Gorgeous Thing! (S10E04)

The teams depart from their Pit Stop at a rice paddy, receiving a clue that sends them twenty miles away by taxi to the Ly Thai To Garden in Hanoi, Vietnam. They are given 588,000 Vietnamese dong, but must retrieve it separately as it isn't included with the clue. Upon arriving at the Garden, they receive an auditory hint that points them towards the Hydrofoil Harbor in Ben Xe Bai Chay. Here, a Roadblock challenges one team member to tackle a steep ascent. Afterward, the teams hop on motorboats for a 1.2-mile journey to the Song Sot Cave, where they must decide between two tasks in a Detour: Over (delivering supplies) or Under (hauling oysters). Navigating the boats proves tricky, leading to a thrilling conclusion.
