Still one of the highest points in the Santa Cruz Mountains, even though the military graded and flattened the actual summit to create an Air Force base. The summit was cleaned of hazardous material in 2009, then carefully restored after a lot of community input. It's a lovely place to visit now!

The Mineral Springs Grotto in Alum Rock Park tells the story of the area's geological history and abundance of natural mineral springs. Developed between 1891 and 1902, masons crafted intricate stone grottoes using native rock to protect the springs: sulfur, magnesia, iron, and carbonated soda springs. These springs once supported a thriving health resort, with waters believed to have medicinal properties. Today park visitors can explore the grottoes and interpretive panels along the Creek Trail to learn about the springs’ historical significance and the park’s transformation from an ancient ocean beach to the stunning canyon seen today. Unfortunately, soaking is not allowed these days.
