Boat tours are the best means of navigating Trang An, 95 kilometers south of Hanoi. The dock is located seven kilometers from downtown Ninh Binh, with three tours exploring the maze of limestone karst towers and waterways, which cover over 6,000 hectares (14,800 acres). Tours last three hours and are priced at VND250,000 ($11) per adult, and VND120,000 for children from one to 1.3 meters.
