Historic Mineral Springs Grotto

Alum Rock

Wander through stone grottos built by 1890s masons to showcase bubbling mineral springs. The sulfur-scented waters once drew health-seekers from across California. Now it's a peaceful canyon escape where deer wander and one spring still flows for the curious.
