The principal attraction in Can Gio is Can Gio mangrove forest . Formed by sediment deposits from the Dong Nai and Long Tau Rivers, this forest contains a high degree of biodiversity with more than 200 species of fauna and 50 species of flora. However, as with many ‘ecotourism’ activities in Vietnam, Saigon Tourist has got in on the act and turned the experience into a bit of an event. Kayaking in the mangroves is a great concept, but the animal circus just doesn’t do it for us.
