A Summer Under the Stars: SDSU’s Mount Laguna Observatory Program

Star parties are back at Mount Laguna with the return of the Summer Visitors Program at the Mount Laguna Observatory.

The public programs will be held on Saturday nights from 8 to 11 p.m., May 23 through August 15, with a special bonus mid-week viewing scheduled for Wednesday, August 12.

High above the busy streets of San Diego, tucked among pine forests in the mountains east of the city, sits one of the region’s most fascinating hidden gems: San Diego State University’s Mount Laguna Observatory. Every summer, students, researchers, and curious visitors head into the cool mountain air to experience astronomy far away from the glow of city lights.

Located about 45 miles east of downtown San Diego inside the Cleveland National Forest, the observatory sits at an elevation of over 6,000 feet. The remote location provides exceptionally dark skies, making it one of the best observing sites in Southern California. According to SDSU’s astronomy department, the observatory benefits from a high percentage of clear nights and excellent viewing conditions throughout much of the year.

For the public, summer also means the return of the observatory’s popular visitor nights. Saturday evening programs allow guests to attend astronomy lectures and, weather permitting, look through the historic 21-inch Reginald Buller telescope. These nights often become unforgettable experiences for families and first-time stargazers seeing Saturn’s rings or distant star clusters with their own eyes

Beyond the science, part of the observatory’s magic comes from the setting itself. The drive along Sunrise Highway winds through forests, granite peaks, and sweeping mountain vistas. By sunset, temperatures are often far cooler than the city below, and as darkness settles in, the Milky Way begins to emerge overhead in stunning detail.
