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.

I was fortunate to be part of a school group that had a private tour of the observatory. The guide was excellent; a retired engineer and amateur astronomer, he was able to provide an in-depth explanation of the observatory, its construction, the manufacture of the...More

This place is far out up in the mountains. The route to the observatorium is very sceneric and is surely a part of the visit. To be where so many discoveries have originated is out of this World. Pun intended.

The biting flies/gnats around the area were atrocious! Small museum with models and placards of history. Short walk to telescope (several stairs) viewed through a glass wall. Long winding road to get to location. Just ok.

Hi Irene. I'm afraid you cannot. In fact, no one can look through it anymore since all eyepieces were removed decades ago. Hardly any research telescope allows anyone look through it (astronomers work behind computers since... More

I don't think so the only think that may be difficult is to climb up the observatory theres a lot of stairs to climb. But it is a nice area for walking around maybe check out the shop there.
