Mount Wilson

Mount Wilson is a summit in the San Gabriel Mountains in California that has been used for astronomical observation for over a century. The site is marked by broadcasting towers that stand alongside historical telescopes at its highest point.

Benjamin Davis Wilson built a trail to this mountain in 1852, creating access that would enable future discoveries. In the early 20th century it became a leading center for astronomical research.

The observatory on this summit represents a place where early 20th-century astronomers made groundbreaking discoveries about galaxies and the universe. It embodies the scientific curiosity and innovation that shaped modern astronomy.

Visitors can reach the summit by car or hiking trail, with parking and basic facilities available at the top. Mountain conditions require proper footwear and caution on steep sections of the trail.

On clear days visitors can see dozens of miles into the distance and even spot the Channel Islands in the Pacific Ocean. This rare visibility makes the summit a favorite spot for photographers and nature observers.
