Palomar Mountain is a mountain ridge in the Peninsular Ranges in northern San Diego County. It is famous as the location of the Palomar Observatory and Hale Telescope, and known for the Palomar Mountain State Park.
The Luiseno Indian name for Palomar Mountain was "Paauw" and High Point was called "Wikyo."
The Spanish name "Palomar", in English meaning "pigeon roost," comes from the Spanish colonial era in Alta California when Palomar Mountain was known as the home of band-tailed pigeons.
During the 1890s, the human population was sufficient to support three public schools, and it was a popular summer resort for Southern California, with three hotels in operation part of the time, and a tent city in Doane Valley each summer.
