6. Hoan Kiem Lake
Hoan Kiem Lake (Hồ Hoàn Kiếm) is the historical center of Hanoi. One of the major tourist attractions in Vietnam, it is full of scenic spots and serves as a focal point for public life. The small lake is surrounded by restaurants, cafes, temples, shops, park benches, street sellers, street performers, and what not. It is ideal for walking, jogging, exercising and roaming around. I daresay there are 2.5 tourists for every native!?
