Visits to the Facilities in Chile

ESO is happy to welcome tourists, students, journalists and TV crews at its La Silla, Paranal and ALMA sites in Chile. The capacity of the facilities is limited, therefore visits are organized in such a way that they do not disturb the work at the observatories.

Please note that all media visits require authorization in advance by the ESO Department of Communication. You can find guidelines for media visits here.
