Group Tours at Palomar Observatory
Group Tours are for groups of 20 - 40 people and are by reservation only. For more information email: dmck@astro.caltech.edu The tours are one-hour-long.
The tour is not recommended for children under six years of age. Sorry, no pets on tours.
Please note that the interior of the 200-inch dome is kept at nighttime temperatures (for an elevation of 5,500 feet!). Temperatures inside the dome are often in the 30s & 40s in November through April. Dress accordingly. High-heeled shoes are not recommended for the tours. Keep in mind, Palomar Observatory is a research facility. There is no viewing through the Hale Telescope as a part of the tours. [an error occurred while processing this directive]
