The trip starts underground, in the Cu Chi tunnels northwest of Saigon, then heads down to the Mekong for the afternoon: a bee farm, a coconut village and traditional music on the water.
Day two covers Saigon properly before lunch, with the Independence Palace, Notre Dame Cathedral and the Central Post Office, then flies to Da Nang in time for Hoi An Ancient Town the same evening.
The rest belongs to the centre. A full day at Ba Na Hills, a long day over to Hue for the mausoleum of Khai Dinh, the Imperial Citadel and Thien Mu Pagoda, and a gentler last day at Cam Thanh coconut village and Tra Que vegetable village, where the growing beds are 400 years old.
