What Cam Thanh actually is
Cam Thanh is a tidal river-mouth district 4 kilometres east of Hoi An's Old Town, where nipa palm (often called 'coconut palm' by tourists, though technically different) grows on small islands separated by salt-water canals. The area covers about 110 hectares and was originally a Viet Cong hiding base during the Vietnam War — the dense palm canopy provided cover from American aerial surveillance.
Today Cam Thanh is the most-visited countryside landmark in the Hoi An area. About 60 families operate basket boats for visitors, fish in the canals, and harvest coconut palms for thatch. The whole place is small enough that you can paddle a full circuit in 30 to 45 minutes.
The specific palm species growing here is Nipa fruticans, a brackish-water palm whose leaves were historically the main roofing material for Hoi An's wooden houses. The 'coconut forest' nickname stuck because the dense palm canopy looks similar.
