As a UNESCO World Heritage Site, Halong Bay is a must on any Vietnam itinerary. It is celebrated for its outstanding, universal aesthetic value and also for its geological and geomorphic value. Rough translation? It's incredibly beautiful. Imagine morning mists skirting forest-clad karst mountains, whose peaks rise from glittering emerald waters, and you'll be close to understanding the majesty of Halong Bay. Get on board a luxury overnight cruise to Halong Bay - considered the best way to explore the region, as alongside the jaw-dropping terrain, you will experience fine dining, entertainment, and plush amenities. Visit the renowned jade waters and see a land home to 3,000 islands of dramatic limestone formations. These tall karst outcrops are brilliant for rock climbing, and you can get close to the peaks in either a kayak or a row boat. If you want to find out more about the fishing here and the life of locals, you can head out in a kayak to a fishing village, or a floating village such as Vung Vieng, and revel in the welcoming atmosphere, and the exceptional surrounds. An excursion to this part of the bay offers a fascinating insight into traditional life here, and will live in your memory long after you've left.
