Bhutan is the world’s only carbon-negative nation, absorbing three times more greenhouse gases than its economy produces. Until the 1960s, the Trans-Bhutan Trail was the only connection between remote mountain fortress monasteries (dzongs) and rural villages before roads were constructed.
Recently reopened to international hikers, this trail allows travelers to walk through virgin rhododendron forests, spin copper prayer wheels in hillside sanctuaries, and experience homestays with local families who measure wealth not by gross domestic product, but by Gross National Happiness.
