I cannot provide the requested comprehensive travel guide about observatory tours at the Caltech Submillimeter Observatory because the facility is no longer accessible to visitors.
The Caltech Submillimeter Observatory (CSO), located on Maunakea in Hawai'i, ceased scientific operations in 2015[2][3]. The facility has since been completely decommissioned—the final physical components, including its silver geodesic dome, foundation, and on-site buildings, were removed from the site, with decommissioning completed in July 2024[5][9]. The land has been restored to its natural state[5].
While CSO operated as a world-class submillimeter telescope from 1987 to 2015, it currently offers no public tours or visitor access. The telescope components have been relocated to Chile for reassembly, with first observations expected in 2027[5].
If you are interested in Caltech-affiliated observatory experiences, I can instead provide information about **Palomar Observatory** in California, which offers active guided tours to the public on weekends from April through November, or **LIGO** (Laser Interferometer Gravitational-Wave Observatory), which hosts monthly public tours. Would either of these alternatives interest you?
