Latin America Trip Leader

Bernardita De Negri

Bernardita de Negri, born in Buenos Aires, grew up in a family that had immigrated from Europe to Argentina. Her family loved travel, books, and languages, and her international background, combined with living in cosmopolitan Buenos Aires, helped her develop a lust for world travel and a curiosity about other cultures. Bernardita studied hotel and tourism management, lived abroad for a while, and then built a career as a travel consultant. Having always loved being close to nature, she found ways to experience the great Argentine outdoors despite living in a city. After multiple Patagonian adventures in camping, trekking, and sailing, she decided to dedicate her life to natural history studies and began a career as a professional guide. "My life as a Trip Leader lets me indulge my passion for travel and the outdoors, and at the same time I can share my knowledge of Patagonia and contribute to the development of nature tourism in my country." Bernardita lives in Buenos Aires and speaks fluent English.
