This updated guidebook, with a focus on responsible tourism, offers greater coverage than any other to the Chittagong Hill Tracts where 13 different ethnic groups live, and to the world's largest mangrove forest at the Sundarbans. Personal insights and anecdotes guide trailblazing travellers to those aspects of the country that are almost unknown to visitors - dolphin and whale watching, winter bird-watching in the northern wetlands and golden Bengal's silk and archaeological highlights.
