Siem Reap, the gateway to Angkor Wat, can kickstart a romantic getaway that few places can match for atmosphere and adventure.
The city's French colonial atmosphere is largely preserved, particularly around around Sivutha Street and the Old Market area. You can buy presents for your love at Psar Leu's jewelry and woodcraft shops, or enjoy a candle-lit dinner at one of the many restaurants now proliferating in the city.
Of course, a trip to Siem Reap just isn't complete without visiting the temples in Angkor, the 12th-century Khmer capital. For many couples, watching the sun rise from Angkor Wat serves as the highlight of the trip. You can also bring your significant other to ride the balloon that gives you a birds'-eye-view of Angkor Wat and its neighboring temples.
