Sacramento has a secret — and it’s buried beneath your feet.
Beneath the sidewalks of Old Sacramento lies a shadowy world frozen in Gold Rush time. On the Sacramento Underground Tours, you don’t just hear about history — you walk straight into it.
Brick passageways. Hollow sidewalks.
Entire streets entombed after the city raised itself to escape devastating floods in the 1860s.
The air feels cooler down there. Quieter.
Lantern light flickers against old foundations while stories of fortune-seekers, fires, and floods echo through the corridors. It’s gritty.
A little eerie. Completely unforgettable.
Up above, modern Sacramento hums along. Down below, the Gold Rush never quite ended.
If you’re craving a history lesson with dust on its boots and secrets in its shadows, this underground adventure delivers a side of California most visitors never see.
The Gold Rush Origins of Old Sacramento

Before the glittering gold nuggets and the roaring crowds arrived, Sacramento was little more than a trading post near the confluence of two rivers. When gold was discovered at Sutter’s Mill in January 1848, everything changed almost overnight.
Thousands of fortune-seekers poured into the region, turning a quiet settlement into a boomtown that could barely keep up with its own growth.
The Underground Tours begin right here, at the Sacramento History Museum, where guides dressed in authentic 1800s attire set the stage for the story ahead. You learn that Sacramento became the supply hub for the entire Gold Rush, meaning merchants often made more money than the miners themselves.
Dry goods, shovels, and boots flew off shelves faster than they could be restocked.
What makes this starting point so compelling is how grounded it feels in real human experience. The tour does not just throw dates and facts at you.
Instead, your guide speaks as a character who actually lived through these events, making the history feel personal and immediate. Understanding where Sacramento came from makes everything you see underground that much more meaningful and alive.
Flooding Chaos That Forced the City Underground

Sacramento sits at the meeting point of the Sacramento and American Rivers, which sounds scenic until you realize what that meant for early residents every single winter. Catastrophic flooding hit the young city repeatedly throughout the 1850s, destroying homes, wiping out businesses, and even killing people.
At one point, the entire downtown area sat under several feet of water for weeks at a stretch.
Locals tried everything to survive the floods. Some families lived on the second floors of their buildings for months at a time, using rowboats to get their groceries.
The mud, disease, and destruction were relentless, and many newcomers simply packed up and left. Those who stayed, however, started thinking creatively about how to fix the problem permanently.
The Underground Tours bring this chapter of Sacramento’s story to life with vivid detail. Your guide explains how the flood disasters were not just inconvenient but genuinely life-threatening, shaping every major decision the city made for decades.
Hearing these stories while standing in the actual spaces where people once lived and worked adds a layer of emotional weight that no textbook can replicate. The flooding crisis is what ultimately led to one of the most audacious engineering feats in California history.
The Bold Plan to Raise the Entire City

When repeated flooding proved too costly to ignore, Sacramento’s leaders made a decision so bold it sounds almost unbelievable today. They decided to physically raise the entire city by filling in the streets with dirt and debris, lifting the ground level by as much as ten to fifteen feet in some areas.
This massive engineering project took years to complete and required the cooperation of nearly every property owner in the downtown core.
Workers used a combination of hydraulic jacks, fill material, and sheer determination to lift buildings off their original foundations. Some structures were raised while people continued to live and work inside them.
Imagine eating breakfast while your house slowly creaks upward, inch by inch, over the course of several days. That was the reality for many Sacramento residents in the 1860s.
The Underground Tours give you a front-row seat to the evidence of this remarkable project. When you step into the lower levels of the historic buildings along I Street, you are literally standing at the original street level from the Gold Rush era.
Your guide points out old doorways, window frames, and storefronts that once faced a bustling avenue. It is one of those rare moments where history stops being abstract and becomes something you can physically touch.
The Sacramento History Museum Starting Point

Every great adventure needs a proper starting line, and for the Underground Tours, that place is the Sacramento History Museum at 101 I Street. Tucked into the heart of Old Sacramento’s historic district, the museum sits just steps from the waterfront, surrounded by wooden boardwalks and 19th-century facades that immediately put you in the right mindset.
The building itself has a story worth knowing before you even buy your ticket.
Tour tickets are priced at around $25 to $30 per person and include full admission to the museum, making it genuinely good value for the amount of content you receive. The museum houses artifacts, exhibits, and photographs that flesh out the context for everything you will see on the underground portion of the tour.
Spending a few minutes inside before or after the tour can significantly deepen your appreciation for the stories your guide shares.
One thing worth knowing before you visit: tours run Wednesday through Sunday from 10 AM to 5 PM, and the space fills up quickly, especially on weekends. Booking your spot online in advance is strongly recommended so you are not left disappointed after making the trip.
The phone number for reservations is +1 916-808-7059, and the official website is sachistorymuseum.org, where you can also check for any schedule updates.
Character-Based Tour Guides Who Steal the Show

One of the most talked-about elements of the Underground Tours is the way guides bring history to life by fully inhabiting a character from Sacramento’s past. Forget dry lectures and laminated fact sheets.
Your guide might be Madame Anne Seymour, a sharp-tongued businesswoman from the 1850s, or Sam Clemens, the young journalist who would later become Mark Twain. Each character comes with a completely unique set of stories, perspectives, and personality quirks.
Because different guides portray different historical figures, no two tours are exactly alike. A visitor who comes back a second or third time will hear entirely new stories told from a fresh point of view.
One guide might focus on the dangerous lives of miners, while another zeroes in on the role women played in building Sacramento’s economy. The rotating cast of characters keeps the experience feeling fresh and layered.
Reviewers consistently praise the guides as the heart of the whole experience. Words like “super knowledgeable,” “passionate,” and “genuinely enthusiastic” appear again and again in visitor feedback.
A headset with volume control is provided so you can hear every word clearly, even in noisier outdoor sections. And if you feel moved to tip your guide at the end, know that they have absolutely earned it with every dramatic pause and historical detail they deliver.
Walking Through the Original Street Level

Here is something that surprises almost every first-time visitor: when you go underground on this tour, you are not walking through a tunnel or a mine shaft. You are walking along what used to be the actual street level of Sacramento during the Gold Rush era.
The roads, doorways, and storefronts you see were once open to the sky, busy with horses, merchants, and gold-seekers going about their daily lives.
After the city was raised, these ground-floor spaces became basements and sub-levels, essentially sealed off from the new city above. Some areas remained accessible through building foundations, preserving an eerie snapshot of mid-1800s Sacramento that time largely forgot.
The walls still carry the marks of daily life, and in certain spots, you can see original brickwork, old window openings, and architectural details that have survived for over 150 years.
Walking through these spaces feels genuinely surreal in the best possible way. The air is cooler down here, slightly damp, and carries a faint mustiness that feels entirely appropriate given the age of the surroundings.
Reviewers have suggested wearing comfortable shoes you do not mind getting a bit dusty, which is practical advice. Photography is not permitted in the underground sections, which actually encourages you to slow down and really absorb what you are experiencing.
Artifacts Preserved from the 1840s and 1860s

Scattered throughout the underground spaces are physical remnants of Sacramento’s earliest decades, objects that somehow survived the floods, the fires, and the passage of nearly two centuries. Old bottles, ceramic fragments, tools, and architectural hardware turn up in the preserved lower levels, each one a tangible link to the people who once used them.
Seeing these items in context, rather than behind glass in a conventional museum display, gives them an entirely different kind of power.
Your guide will point out specific artifacts and explain what they tell us about daily life during the Gold Rush period. A simple glass bottle might reveal where goods were imported from.
A particular style of brick might indicate which decade a wall was constructed. These small details add up to a surprisingly rich picture of how Sacramento evolved from a tent city into a permanent urban center in just a few years.
The Sacramento History Museum also houses a broader collection of artifacts that complement what you see underground. Spending time with those exhibits before or after the tour helps connect the physical objects to the larger historical narrative your guide presents.
For anyone with a curiosity about material culture or hands-on history, the combination of the museum and the underground spaces offers a genuinely satisfying and educational afternoon experience worth every penny of the ticket price.
How the City Was Rebuilt After Repeated Disasters

Sacramento burned down multiple times in its early years, flooded almost every winter, and still managed to rebuild itself faster than most cities twice its size. That stubborn refusal to quit is one of the most compelling themes running through the Underground Tours, and it comes through clearly in every story your guide tells.
The city’s resilience was not accidental; it was a conscious, collective choice made by thousands of individuals who had too much invested to walk away.
After the major flooding disasters of the 1850s, city leaders pushed through a massive infrastructure overhaul that included not just raising the streets but also improving levees, installing better drainage systems, and replacing flammable wooden buildings with more durable brick structures. The transformation was remarkable, turning a chaotic frontier settlement into something that actually resembled a real city within the span of about two decades.
The tour traces this arc of disaster and recovery with a kind of quiet admiration for the people who made it happen. You come away with a genuine appreciation for how much effort, creativity, and community spirit it took to build something lasting out of such unpromising circumstances.
For visitors who grew up in the Sacramento area, this part of the tour often sparks a new sense of pride in a city they thought they already knew well.
Practical Tips for Planning Your Underground Tour Visit

Getting the most out of your Underground Tours experience starts with a little planning before you leave home. Tours run Wednesday through Sunday from 10 AM to 5 PM, and the venue is closed on Mondays.
One reviewer learned the hard way that website information about last ticket times can sometimes be out of date, so calling ahead at +1 916-808-7059 to confirm the day’s schedule is always a smart move before driving a long distance.
Tickets run approximately $25 to $30 per person and include museum admission, which makes the pricing quite reasonable for what you get. Booking online in advance through sachistorymuseum.org is strongly recommended, especially on weekends when spots fill up fast.
The tour lasts roughly 60 to 90 minutes depending on your guide and group, so factor that into your day when planning meals and other activities nearby.
Wear comfortable, closed-toe shoes since the underground sections can be uneven, slightly dusty, and a bit damp in cooler months. Parking is available on nearby streets using city meters at around $1.75 per hour, which is manageable for a two-hour visit.
Old Sacramento has plenty of restaurants and shops within easy walking distance, making it simple to turn the tour into a full and memorable day out along the historic waterfront.
