Rispin Mansion Community ParkOpen to visit
Built in 1921 not as a home but as a 22-room real-estate showroom to lure Depression-era investors, Henry Rispin's mansion went bankrupt, became a convent, then sat vandalized and abandoned for over two decades, earning a 'cursed' reputation investigated by the Santa Cruz Ghost Hunters — a 2009 fire gutted three-quarters of it, and 2012 repairs sealed the shell shut for good, so today the mansion is permanently locked but the surrounding grounds just reopened as public parkland.

Seacliff State Beach — SS Palo Alto wreckView only
A WWI concrete tanker too late for the war was towed here in 1930 and refitted as a floating ballroom-and-café amusement pier — it cracked in half in a 1932 storm, was sold to the state for $1, and has spent nine decades slowly disintegrating into Monterey Bay; the pier out to it was finally demolished in March 2023 after successive winter storms tore the stern off, leaving the rusted concrete hull visible as an offshore ruin and artificial reef.
-
Enriquita MineView only
Established in the 1850s, the Enriquita Mine was a productive cinnabar mine that supplied mercury to the California Gold Rush. Today, the site is preserved within Almaden Quicksilver County Park, where the historic shafts have been sealed for safety. Hikers can explore the area via the Enriquita Trail to see rusted remnants of old mining equipment amidst scenic views of the Santa Cruz Mountains.
-
Senator MineView only
Opened in 1863, the Senator Mine (historically spelled Senador) was a highly productive cinnabar mine that supplied mercury to extract gold during the California Gold Rush. It operated intermittently until 1926, leaving behind a legacy of heavy industrial activity. Today, the site lies within Almaden Quicksilver County Park, where the massive, crumbling concrete towers of its 1915 Herreschoff furnace and dust bins still stand along the trail.
-
Pier 90 Grain SilosView only
Built in 1918, this massive 190-foot-tall concrete grain terminal on San Francisco's southern waterfront once stored and loaded barley onto cargo ships. Operations permanently ceased following damage from the 1989 Loma Prieta earthquake, leaving the structure abandoned for decades. In 2014, the towering silos were adorned with 'Bayview Rise,' a giant, illuminated temporary mural that remains a prominent neighborhood landmark.
-
Pogonip Historic Lime KilnView only
Dating back to the late 19th century, these massive stone kilns were built by industrialist Henry Cowell's workers to process limestone into lime for San Francisco's early buildings. Today, the towering, moss-covered masonry structures stand abandoned in a dense redwood forest, slowly being reclaimed by nature. Visitors can admire the impressive ruins and read an educational placard from the safety of the public trail.

Old Lime Kiln RuinsOpen to visit
Tucked away in the redwood forest of the Fall Creek Unit of Henry Cowell Redwoods State Park, these moss-covered stone ruins are the remnants of a massive 19th-century lime-burning operation. Established in the 1870s by the IXL Lime Company, the facility heated quarried limestone to produce lime used in mortar and plaster, heavily supplying the rebuilding of San Francisco after the 1906 earthquake. Today, hikers can explore three towering, granite-block kilns, an old powder house, and a nearby barrel mill site, all slowly being reclaimed by ferns and redwoods.
