You step off the plane at Noi Bai and the humid air of Northern Vietnam greets you; mopeds hum like distant insects and the scent of pho gathers in narrow streets. Over twelve days you move from Hanoi’s colonial avenues to the mist-wrapped rice terraces of Sapa, across the carved limestone towers of Ha Long Bay, down the Mekong’s braided channels, and finally into the sandstone quiet of Angkor’s temples in Siem Reap.
