It’s the region few foreign or even Indian tourists visit -- the northeast, bounded by China (Tibet) and Bhutan to the north and Bangladesh to the south. Historian, writer, and journalist David Mould travels along the wide valley of the Brahmaputra to the Hindu monasteries of Majuli Island and the fortresses and palaces of the Ahom empire, then heads south into the hills of Meghalaya—to the colonial hill station of Shillong, the “Scotland of the East,” and to Cherrapunjee, whose claim to fame is that it is “the wettest place in the world.” Registration required.
