"Le Quoc Thuong, the resident biologist at Six Senses Ninh Van Bay, is the first terrestrial biologist within the hotel group, resulting from a long-term collaboration between the luxury resort and Vietnam's GreenViet Biodiversity Conservation Center. While on vacation, guests have the unique opportunity to partake in guided hiking trips to learn about forest life and see firsthand how the resort is studying and protecting the langurs. Guests can even have a chance to observe the black-shanked douc langurs, a critically endangered monkey species." - Travel + Leisure Editors
