Mount Wilson Observatory
Tours allow visitors to enter the area directly beneath the 100-inch Telescope and entrance into the 60-inch dome. On most tours, their solar astronomer will have the 150-foot solar tower telescope open as well, providing an opportunity for visitors to safely observe the sun.
Visitors are also welcome to do self-guided tours using the visitor’s guide. Private tours can be scheduled and include a walk around the grounds, a talk on the story of the institution, and visits to the major telescopes.
