SACRAMENTO — Responding to the demand for more Old Sacramento Underground tour availability, tours are now available on Mondays through Labor Day.

On most Mondays, four tours have been added and are offered from 10:30 a.m. until 12:30 p.m. Then, on Labor Day (Monday, Sept. 5), an expanded tour schedule is available with tours departing every half hour from 10:30 a.m. until 3:30 p.m. With schedules that fluctuate with the seasons, Old Sacramento Underground tours continue through Sunday, November 27. Interested tour participants are encouraged to check the website -- www.historicoldsac.org -- for tour dates, times and availability.

“For a variety of reasons, possibly long weekends or hold-over stays during conventions, visitors to Old Sacramento have been asking for underground tours on Mondays,” said Marcia Eymann, Executive Director of the Historic Old Sacramento Foundation. “We are pleased to be able to respond accordingly with Monday tours at least for the next four weeks.”

Old Sacramento has the distinction of being the only city in California to raise its streets in the 1860s through the 1870s to protect the city from devastating flooding. Tour participants explore excavated foundations, an open archeological site and enclosed pathways all 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.

The Old Sacramento Underground tour program is coordinated by the Historic Old Sacramento Foundation (HOSF) and in partnership with the City of Sacramento, California State Parks, Old Sacramento Business Association and participating merchants and businesses.

Tours of the underground last approximately one hour in length and cost $15 for adults and $10 for children. As a benefit of membership, Historic Old Sacramento Foundation members receive a discounted $12 adult ticket price. Tour check-in is located at the Sacramento History Museum, 101 I Street in Old Sacramento. Underground visitors will need to be prepared to walk on uneven surfaces in areas that have low ceilings and in occasional small spaces. Box office questions can be sent via email to scox@cityofsacramento.org and more information about Foundation membership is available by calling 916-808-7059.
