The delta, which yields enough rice to feed the country with a sizable surplus, was formed by sediment deposited by the Mekong. The process continues today, with silt deposits extending the shoreline by as much as 80m per year. The river is so large that it has two daily tides. Lush with rice paddies and fish farms, this delta plain also nourishes the cultivation of sugarcane, fruit, coconut and shrimp. Although the area is primarily rural, it is one of the most densely populated regions in Vietnam and nearly every hectare is intensively farmed.
The uniquely southern charm with its welcoming introduction to life along the river is the real draw, and visitors can explore quaint riverside towns, sample fruits bartered in the colourful floating markets or dine on home-cooked delicacies before overnighting as a homestay guest. Other highlights include visits to local orchards, flower markets and fish farms. There are also bird sanctuaries, rustic beach getaways like Hon Chong and impressive Khmer pagodas in the regions around Soc Trang and Tra Vinh.
Those seeking an idyllic retreat will find it in Phu Quoc, a forested island dotted with pretty beaches, freshwater springs and empty dirt roads (ideal for motorbike adventures). Good diving and white-sand beauty have led to its growing popularity, with a mix of cheap bungalows and five-star resorts along an uncrowded coastline.
