Forestiere Underground Gardens

Carved entirely by hand over four decades beneath the scorching San Joaquin Valley floor, Forestiere Underground Gardens is one of California's most extraordinary hidden gems. Sicilian immigrant Baldassare Forestiere spent more than 40 years excavating a sprawling underground world of rooms, grottos, and courtyards — complete with fruit trees that grow up through skylights to reach the sun above. A genuinely one-of-a-kind attraction that defies easy comparison.
