We start today’s activities exploring the California Academy of Sciences from an insider's perspective and spend an hour behind the scenes learning more about the institution's 159-year history and how its scientists are tackling critical questions about life on earth. Visit the research collections and a working laboratory, get closer to the living roof, and see breathtaking geology specimens in the vault. A general admission ticket and a one-hour behind the scenes at the Academy are included. The rest of the day is yours to explore this vibrant city. Before dinner at a local Chinese restaurant, we’ll embark on a walking tour in San Francisco’s famous Chinatown. (BB, HD)
