Visits to the Facilities in Chile

"ESO is happy to welcome tourists, students, journalists and TV crews at its La Silla and Paranal sites, and journalists and TV crews to the ALMA site in Chile. Visits will be organised within the limited capacity available and in such a way that they do not disturb the progress of work at the sites."
