Nha Trang is Vietnam’s most famous seaside resort-town. It's more lively and urban in character than other beach destinations like Mui Ne and Phu Quoc. It's also the scuba diving center of Vietnam. Traces of human settlement in Nha Trang date back to the Cham Empire, though in times of Vietnamese rule, there wasn’t much more than small fishing villages. The French recognized that this beautiful bay, with its islands and white sand beaches, made for a perfect bathing spot, and began the transformation into a resort town. American soldiers agreed, and Nha Trang became a favorite vacation stop during the war. The monsoon season is from October to mid December. Sea winds can be heavy, and sometimes the weather can get pretty chilly. Summer, naturally, brings many vacation goers into town and hotel rooms get somewhat more difficult to find.
