The best of Vietnam, from north to south

From the heights of plunging mountain vistas at the top of the world in northern Vietnam to the watery depths of the Mekong Delta in southern Vietnam, a tour through this long, skinny country is ever-changing. two areas stand out above all others: Sapa and the Mekong Delta. Unfortunately for the visitor with limited time, they are on opposite ends of the country, 1,270 miles (2,047 km) apart.
