Walking tours of the Mount Wilson Observatory depart on Saturdays and Sundays at 1:00 p.m. from the Cosmic Cafe located in the Pavilion above the large parking lot at the Observatory entrance.
Weather permitting, the tours take place from the first weekend of April through the last weekend of November.
One notable feature of the tour is admission to the "bull ring" area beneath the 100-inch telescope.
