Phu Quoc National Park
About 90% of Phu Quoc is forested and the trees and adjoining marine environment enjoy official protection. This is the last large stand of forest in the south, and in 2010 the park was declared a Unesco Biosphere Reserve. The forest is densest in northern Phu Quoc, in the Khu Rung Nguyen Sinh forest reserve; you’ll need a motorbike or mountain bike to tackle the bumpy dirt roads that cut through it. There are no real hiking trails.
