Where we provide experiences that connect us to the wonders of the cosmos at the very place where the universe was discovered.

Please be advised when visiting the mountain:

•  There is no reliable cell service once you start up Angeles Crest Hwy or on our campus.

•  There are no gas stations on the mountain; the closest is 20 miles away in La Cañada.

•  An Adventure Parking Pass is required for daytime parking in the main lot and can be purchased at the Cosmic Café.

•  There is a 10-minute walk from the parking lot to the Auditorium or Domes.  Comfortable shoes are recommended.

•  Mount Wilson's elevation is 5,700 ft. Those with heart or respiratory problems may have trouble with the altitude. 

•  It is much cooler on the mountain in the evenings - come prepared with warm clothing.

•  As our facilities are over 100 years old, they are not ADA-compliant.  Paths and stairs are not accessible for those with physical disabilities.

•  It is imperative to arrive on time for evening events.  Our gates close shortly after the beginning of any evening program and latecomers will not be able to enter.

•  Restrooms are limited.  Please see our map (CAMPUS MAP).  Restrooms can be located by the Cosmic Cafe, and limited bathrooms are available at the Auditorium.  During events, porta-potty bathrooms can be found outside the 100-inch telescope dome.
