Arrival at Paranal
At the guard desk, you will be asked for your name(s) and Release Forms. If you are on the approved visitor list, you will be asked to proceed to either the tour starting point (Tours, students) or the Residencia offices (Journalists, family).
Tours will begin at the Visitors Center. There is a brief presentation on the construction of the VLT, Paranal, and astronomy. Other visitors will be assigned a meal card and given room keys (if overnight stays are involved). Your contact person will be informed of your arrival.
The VLT Tour
During the tour, you will be taken to the mountain top where the telescopes are located. You will have the chance to enter one of the enclosures and see the actual telescope. We encourage you to ask as many questions and take as many pictures as you would like.

While on Paranal
All buildings and public areas on Paranal are non-smoking.
During your visit, you should stay with the ESO Guide at all times. In an emergency, always follow the Guide´s instructions.
The Paranal Site of the La Silla Paranal Observatory permits photographs and video taping during the tours.
Paranal´s basecamp is located at 2,456 metres. The telescopes are at 2,600 metres. We recommend that you do not walk quickly.
For safety reasons, children under 5 years are not allowed.
You are welcome to bring a light snack or lunch. There are no facilities on-site that offer meals. We recommend that you limit intake as excess can cause stomach inflammation and digestive problems at high altitudes. You will be allowed on site one half hour before the tour is scheduled to begin, and restroom facilities are available.
Please wear appropriate clothing such as pants, walking shoes (no sandals), sunglasses, etc. We recommend a jacket/sweater for the VLT enclosures, which are kept at 5–11°C.
While exposed to sunlight, we recommend the use of UV-rated sunglasses--especially while walking on the telescope platform.
Ask questions! The more questions you ask, the more you will learn. The Guides are trained to answer your queries
