Mount Wilson Observatory

Mount Wilson Observatory is home to two of the world’s largest telescopes available for public use.

Public tours are available on weekends where visitors are able to enter the area directly beneath the 100-inch telescope and entrance into the 60-inch dome. On most tours, the 150-foot solar tower telescope will be open too, providing an opportunity for visitors to safely observe the sun.

Special events like Concerts in the Dome and Public Ticket Nights are scheduled throughout the year.
