Concierge.com's insider take:
A good way to get your bearings in Hanoi is to take a quick stroll around Hoan Kiem Lake, a pleasant 30-minute circuit. The lake is fringed with willows, myrtles, flame trees, and tamarinds. Legend has it that the 15th-century emperor Le Loi received a magic sword from the lake, which he used to expel Chinese occupiers. After his victory, he returned the weapon to a golden tortoise, which vanished with it into the lake's depths (Hoan Kiem means "restored sword"). An islet on the northern end of the lake contains the Chinese-style Ngoc Son Temple and the remains of an enormous seven-foot, 500-pound tortoise found (sword-free) in the murky lake in 1968. Admission to the isle, which is accessible by the fire-engine-red Huc footbridge, one of Hanoi's most photographed landmarks, is 2,000 Vietnamese dong (about 12 cents). It's also well worth rising at dawn to see the lake at its busiest, surrounded by locals practicing tai chi.
