Discover secrets under Old Sac

Hidden beneath the city for nearly 150 years, Old Sacramento’s underground has long been the capital’s best-kept secret. Old Sacramento Underground Tour visitors have the unique opportunity to uncover the facts behind the legends that lie below historical buildings and sidewalks.

Guests explore excavated foundations and enclosed pathways while entertaining and knowledgeable tour guides recount the tales of the devastation, perseverance and determination that led to California’s only successful street-raising project.

New in 2014, underground tour guests have a special, hands-on opportunity to learn what it was like to raise and level a building by operating “mini-jacks” during the tours. The interactive experience allows guests to gain an understanding of and appreciation for the ambitious yet painstaking process successfully completed by Old Sacramento residents and business owners in the 1860s and 1870s.

Special “adult only” tours are available on three evenings each week in May — Thursdays through Saturdays — where guides lead guests on special walking tours while sharing some of the dark secrets and racy tales lurking in Old Sacramento’s underground history.

Regular tour schedule for May is Friday at 1, 2:30 and 4 p.m.; Saturday, departing every half-hour from 10:30 a.m.-3 p.m.; Sundays, departing every half-hour from 10:30 a.m.-2:30 p.m. and Monday, May 26 (Memorial Day) at 11 a.m., noon, 12:30, 1:30, 2 and 3 p.m.

The “Adult Only” tour schedule in May is Friday and Saturday evening at 6 p.m.

The cost of regular tours is $15 for adults, $12 for HOSF members, $10 for youths (ages 6-17), children 5 and under are free. Adult only tours are $20 for adults (guests 21 and older). Advance tickets are recommended and can be purchased at

 All underground tour guests need to check in at the Sacramento History Museum, 101 I St. in Sacramento, before descending below several historic Old Sacramento buildings and be prepared to walk in areas with uneven surfaces and low ceilings.
