Notable for its extensive mangrove forest, Can Gio is a low, palm-fringed island sitting at the mouth of the Saigon River, some 25km southeast of Ho Chi Minh City. It was formed from silt washing downstream from the river, so don’t expect any white-sand beaches. A few hopeful resorts have sprung up along the murky 10km shoreline.
Of more interest is the forest. This Unesco Biosphere Reserve contains a high degree of biodiversity, with more than 200 species of fauna and 150 species of flora. If you’re looking for a relatively traffic-free route to explore by motorbike, it's a great day trip.
