A wide range of space observatories on the highest mountain in the area, including the largest glass lens historic observatory from the 1880s, and several generations of subsequent observatory systems.
Very informative free tours. If visiting in winter bring warm clothes, as the elevation results in dramatically lower temperatures than in Silicon Valley just below, as indicated by the snow we encountered.
