This California state landmark is a hidden gem -- beneath the surface of the Central Valley. A astonishing network of subterranean tunnels, chambers, and grottos meanders for some 10 acres. 

In the early 1900s, Sicilian immigrant, citrus grower and visionary Baldassare Forestiere began turning what was useless land into a vast network of rooms, tunnels and courtyards as a subterranean escape from the sweltering Central Valley summer heat. Underground micro-climates modify the temperature from 10 to 30 degrees! Using only shovels, picks and other hand tools, Baldassare was inspired to excavate for forty years, going as deep as 25 feet underground and spanning 10 acres. He grew fruit trees and grapevines underground - many of which are still thriving today!

Due to the nature of this historic site, access is only granted through an hour-long walking tour, accompanied by a tour guide.

The Forestiere Underground Gardens site is closed December through February.
