The Observatory is unique because it caters to the general public with programs for amateur as well as experienced star gazers.
The facility is run by the Washington State Parks Department and provides visitors with the chance to look through the 24.5-inch telescope, one of the largest apertures in the USA available for public use. There is also a secondary dome which houses an eight inch Schmidt-Cassegrain reflecting telescope.
The Observatory offers tours and sky-gazing opportunities year-round. The Summer hours are April 1 - September 30, Wed. - Sun., 2 PM to 5 PM and 8 PM to Midnight. Winter hours are Sat. 1 PM to 5 PM and 7 PM to 9 PM and Sun. 1 PM - 5 PM.
