Start with a classic bowl of pho in the Old Quarter; quick, local and a great introduction to Vietnamese flavours. Check vendor opening hours (typically early morning until late).
Explore a cave like Sung Sot or Ti Top and optional kayaking in a calmer bay area; excursions run in the afternoon—check cruise itinerary for exact timing.
Visit Paradise Cave with spectacular stalactites and large caverns; site open daily (usually 8:00am–5:00pm) — allow 1.5–2 hours for walking and photography.
Wander the lantern-lit streets, visit assembly halls and small museums — the town is open broadly from early morning until late but specific museum hours vary; buy entry tickets if visiting monuments.
Visit the Cham temple complex at My Son—open roughly 6:30am–5:30pm; allow 4–5 hours including travel from Hoi An. Book with a guided tour or private car.
Early departure for a full-day tour of the Mekong—travel time is about 1.5–2.5 hours depending on the chosen town; confirm tour itinerary and pickup time.
Have a last meal and leave for Tan Son Nhat Airport in good time—allow at least 2–3 hours for international flights (check your airline’s recommended arrival time).
