"Words can do little justice to the scenery that awaits travelers to Ha Long Bay, a UNESCO World Heritage site. Hundreds of forested limestone karst formations rise from emerald-green waters, looking like slumbering creatures ready to stir. The islands have a legend behind them: The gods sent a family of dragons to assist Vietnam 's emperors in repelling invaders, and the creatures spat out jewels and pieces of jade that turned into the islands. Many tourists come here on a day trip from Hanoi that involves an early departure, a three-hour bus ride to the ferry terminal, and a four-hour cruise along with scores of other boats before a transfer back to the capital. To truly appreciate the natural beauty with a modicum of solitude, take an overnight cruise—waking in the morning to the sight of the mist-shrouded peaks without the distraction of tons of other boats (and their gawking passengers) is unforgettable."
