Everyone should be required to visit Ha Long Bay once in their lives. The UNESCO World Heritage site is a collection of 1,600 sandstone islands towering above emerald blue waters.
Don’t be dismayed by the shabby main port, the real beauty lies off shore. The best way to see the area in on an overnight boat tour. The bay is a favorite among scuba divers, hikers and rock climbers.
On your way back to Hanoi, be sure to visit Tam Coc, the Ha Long Bay on land. Take a row boat ride along the river past limestone towers and through large natural caves that will make you like you are living in The Goonies and searching for one-eyed Willies ship.
