Halong Bay was beautiful!! It was just like the pictures in National Geographic magazine!! We took a boat cruise around the bay. Stopped at a house boat that was also a fish hatchery. interesting.... The best part of the day was kayaking for 45 minutes around the bay, the guide took us into two cove areas. I kayaked in Halong Bay!! Then we stopped on an island and explored some caves. They are not worried about safety like in the states.
