Palomar Observatory

The Palomar Observatory perches atop Mt. Palomar at about 5,500 feet. This elevation is high enough to get snow in the winter and remain cooler than the surrounding lowlands in the summer. Since the Palomar Observatory is an active research facility, access to the telescope is limited to a visitor's gallery inside the dome. Visitors can take a self-guided tour daily from 9 a.m. to 4 p.m., and docent-led tours are also available at selected times and days.
