Da Nang tours cover three very different days from one hotel, which is why it works as the base for central Vietnam. The city has a long beach on the east bank, the Marble Mountains a short drive south, and both Hoi An and Hue within reach for a day. The Dragon Bridge breathes fire at 21:00 on Friday, Saturday and Sunday. Ba Na Hills and the Golden Bridge are 45 to 60 minutes inland by road. No internal flights to book. What you buy with a tour here is the driving and the tickets. The Marble Mountains, Monkey Mountain and Am Phu Cave sunset trip is $26 per adult. Ba Na Hills with the Golden Bridge is $84 per adult and includes hotel pick-up in Da Nang, an air-conditioned coach, an English-speaking guide, buffet lunch, the return cable car ticket and entrance fees, which matters because the cable car alone is 650,000 VND at the gate. The Da Nang city tour is $40 as a group departure with pick-up in the city, and the Da Nang and Hoi An combined day is $36 per adult with hotel pickup and an air-conditioned van. Three days is the comfortable shape: one beach and city day, one for the Marble Mountains and Son Tra, one for Hoi An, 30 km away. Two days works only if you pick a single big excursion and let the other go, and the honest version of that choice is Ba Na Hills against Hoi An. Ba Na is a long, busy, weather-dependent day that children tend to love. Hoi An is a short drive and a slow evening, and it is the one most adults come back talking about. If you want both, book Ba Na first and keep Hoi An as the evening you can move.
