Once the border between North and South Vietnam, Ben Hai River’s southern bank now has a grandiose reunification monument, its stylised palm leaves oddly resembling missiles. Cua Tung Beach’s fine golden sands are just east of here. Ben Hai’s northern bank is dominated by a reconstructed flag tower and a small museum full of war mementos. Ben Hai is 22km north of Dong Ha on Hwy 1.
