Visits to the La Silla Site of the ESO La Silla Paranal Observatory / Visitas al Sitio de La Silla del Observatorio La Silla Paranal

La Silla welcomes visitors every Saturday between 1:30 and 5:00 p.m. except during July and August, since during wintertime the risk of snowstorms compels the management to suspend any visits.

The service provided inside our facilities is free of charge.

Visitors coming to La Silla (or any ESO site) must read and sign a Release Form. This is for your safety as well as for the safety of the instrumentation and organisation. Once signed, the form must be delivered at the observatory gate. An English and Spanish version of these forms (also available at all sites) can be obtained from here: pdf or MW file (English) and pdf or MW file (Spanish). Since the form must be personally signed by the visitor, a mailed copy of the form will not be accepted.

For visit requests please contact recepstg@eso.org, or via phone to the Reception Desk at ESO Santiago, + 56 2 463 3280. Here you can also obtain the latest details, in particular the next available dates for such visits.
