Overview

Palomar Observatory, located atop Palomar Mountain in north San Diego County, California, is a center of astronomical research owned and operated by the California Institute of Technology (Caltech). The Observatory is home to three active research telescopes: the 200-inch (5.1-meter) Hale Telescope, the 48-inch (1.2-meter) Samuel Oschin Telescope, and the 60-inch (1.5-meter) telescope. The research is conducted by Caltech faculty, post-doctoral fellows, and students, as well as by researchers at collaborating institutions. Conceived of almost a hundred years ago, Palomar Observatory has been at the forefront of astronomical research since mid-century. Today, the observatory operates every clear night and is an iconic facility for scientific advancement, instrument development, and student training. The Observatory is a popular destination in Southern California and receives tens of thousands of visitors a year from all over the world. Most come to see the famous 200-inch (5.1-meter) Hale Telescope-for decades the largest effective telescope in operation. Whether you are an astronomy, history, or engineering enthusiast, or simply curious about the Observatory, you will enjoy visiting our museum and taking one of our guided tours of the facility. All are welcome at the Palomar, but we ask that all visitors respect our rules and procedures. Public, guided tours of the 200-inch (5.1-meter) Hale Telescope are available to visitors on the weekends (Saturday and Sunday, start times are 11:00 am and 1:30 pm) spring through fall-typically from the first weekend in April to the last weekend October. The tours are roughly one hour long, and limited-availalbility tickets (sold exclusively on a day-of and first-come, first served basis) are required. Please plan accordingly.

This is a unique place. Our guide Marianne was very friendly and knowledgeable. The observatory is located at the end of a steep winding road, what makes the place even more special. The low temperatures inside may cause some inconvenience to young visitors.

If you're a stargazer you will enjoy this. Definitely fill up the gas tank in Pala before going up. I started up with a half tank and sweated it the whole way down. Also it's cold at 5000+ft so take a coat.

My wife is 8 months pregnant . We would like to visit the observatory as a day trip from LA. Are there unusual risks that we can avoid? ie., Can palomar's altitude be a problem for your pregnant guests?
