The Ho Chi Minh Trail at Sea is a military transport route on the East Sea secretly used by the Vietnam People's Navy and the Liberation Army of South Vietnam to transport weapons and personnel from the North to the South during the resistance war.

From 1962 to 1972, the wharves in Ca Mau province received 76 ships, of which Vam Lung wharf alone received 68 carrying more than 4.3 thousand tons of weapons and military supplies serving the Southern battlefield.

On November 10, 2010, Vam Lung wharf was recognized by the Ministry of Culture, Sports, and Tourism as a national historical and cultural relic.
