Native groups first inhabited this region over eleven thousand years ago. They may have been nomads who came overland from the north of the American continent, or they may have been marine-oriented groups using boats to follow the coastline. At the dawn of the historic period, their successors were the Cochimi, foragers who exploited the natural resources of the coast, the inland plains, and the Sierra de San Francisco. Travelers trekking into this mountainous region can still see the natives' cave art. Spanish explorers arrived in the area in the 16th century. Juan Rodríguez Cabrillo was the first explorer to navigate the coastlines, whereas Sebastián Vizcaíno explored inland, in what is now the biosphere reserve in 1596 on behalf of Gaspar de Zúñiga, viceroy of New Spain.[3]
