Bordered by Ca Mau, the largest mangrove forest beyond the Amazon basin covers 1000 sq km. Home to endangered mammals – including the hairy-nosed otter and the fishing cat – and 187 bird species, the forest was a hideout for the VC during the American War. Thirty-minute boat trips around the forest cost 140,000d.
Ca Mau Tourist can arrange boat tours (US$180), but you can try to get a speed boat to Thu Bay (two hours), followed by a motorbike for 90,000d.
During the American War, the Americans tried to flush out the VC with chemical defoliation, which caused enormous damage to the forests. The heavy rainfall slowly washed the dioxin out to sea and the forest is returning. Many eucalyptus trees have also been planted here because they have proved to be relatively dioxin-resistant.
Unfortunately today the mangrove forests are being further damaged by clearing for shrimp-farming ponds, charcoal production and woodchipping, although the government has tried to limit these activities. In 2002 an area of 80 sq km was preserved as U Minh Thuong (Upper U-Minh) National Park.
