Visit LCO

Before your visit


  • The tour of the Observatory

People visiting Las Campanas Observatory will enjoy a day tour of the Carnegie Institution for Science telescopes. This can include: Swope telescope (40 inches), du Pont telescope (100 inches), and Magellan telescopes (6.5 meters). The telescopes visited on each tour will depend on the availability and the number of people in each group. Please take into account that this is a research facility, and astronomers, engineers, and technicians have priority in the use of telescopes. Visitors are not allowed overnight.
