Wow! Halong Bay was a fabulous destination and a wonderful natural wonder of the world. Halong Bay, a UNESCO World Heritage Site, is a beautiful area with limestone rock structure islands spread amongst the bay. They allow boats to cruise through the bay and enjoy the beautiful scenery.
I arranged an organized two day, one night cruise/tour through my hotel in Hanoi which made it easier for me too, as it was my first excursion in Vietnam. Halong Bay was one of the main reasons I added Vietnam on to my itinerary when I was planning my summer trip, so I was beyond excited to explore the area. If you google image Vietnam Travel, most of the pictures are from Halong Bay. It is so beautiful!
