Trading the misty, narrow alleys of Hanoi's Old Quarter for the wide, riverfront boulevards of Phnom Penh is a journey across the Indochinese peninsula. Both cities share a colonial past and a love of street food, but the pace shifts from the frantic energy of northern Vietnam to the slower, saffron-robed atmosphere of the Cambodian capital.
Flying is the practical choice: you can be exploring the Royal Palace or the Tuol Sleng Genocide Museum the same day. You can compare availability and book tickets for this route on GoAsia.cc.
