Following the Cai river upstream from Nha Trang
The Cai river runs 84 km from its source on Hon Gia Le at 1,812 m to the sea at Cua Lon in Nha Trang. Followed upstream by motorbike it is the fishing fleet and three bridges in the first stretch, the rice of Dien Khanh in the second and the hills of Khanh Vinh in the third, 30 to 35 km by road. I turn back at Khanh Vinh town, where the road climbs the pass.
