Mount Hamilton

Mount Hamilton rises to 1,327 meters in the Diablo Range with views overlooking Santa Clara Valley and San Francisco Bay. A 31-kilometer road with multiple switchbacks connects San Jose to the summit and provides vehicle access.

The mountain received its name in 1861 during California's first geological survey when surveyors William Brewer and Laurentine Hamilton reached the peak. This early exploration contributed to mapping and understanding the region's geography.

The Lick Observatory operates on the mountain and shares its astronomical work with visitors through telescopes and educational programs. This research facility has become a gathering place for people interested in understanding the night sky and celestial objects.

The ascent is accessible by a well-maintained road with gradual elevation changes suitable for most vehicles. Visitors should expect variable weather, as the higher altitude brings cooler conditions and occasional fog.

The slopes are home to golden eagle nesting sites and mark the location where California condors returned after a long period away. This return represented a significant moment in efforts to restore this threatened bird species.
