Which Seattle Underground Tour Should You Book?

Short answer: there are two Seattle Underground tours, run by different companies, and they take you through different tunnels. Bill Speidel’s is the original — bigger groups, funnier, and you can usually walk up and join within the hour. Beneath the Streets caps every departure at 25 people and plays it straight as history, but you need to book ahead. They cost within a dollar or two of each other, so price is not the deciding factor. Group size and tone are.

The two tours at a glance

Because the two companies hold access to different basements, doing both is not as redundant as it sounds. Beneath the Streets says its three passageways “have never been included in previous underground tours” — they were reopened when the company launched in 2013. Locals routinely recommend both, and they are right to.

One thing worth knowing before you compare reviews: Bill Speidel’s barely sells through booking sites at all. It sells from its own site, by phone, and at its First Avenue counter. So the listing you found in an app — including the one on this site — is Beneath the Streets. Review counts across booking platforms measure how widely a tour is distributed, not how good it is.

What you actually see down there

Both tours walk you through the buried original street level of 1890s Seattle: brick and stone retaining walls, timber shoring, old doorway and sidewalk lines, and the underside of the pavement vaults. The modern city sits roughly twenty feet overhead.

Set your expectations on one point, because it is the most common disappointment in both companies’ reviews: you are not underground the whole time. Both tours surface repeatedly and walk street-level Pioneer Square between sections. Bill Speidel’s descends into three sections across about three blocks; Beneath the Streets covers four blocks and three passageways, and is explicit that it means to show the neighbourhood “from both the original and current street levels”. Roughly half your time is above ground. It is a Pioneer Square history walk that goes below the street three times, not a tunnel crawl.

The tone splits sharply. Bill Speidel’s has traded on wisecracking delivery since 1965 and leans hard on the jokes — some reviewers find them dated, and guide quality is the single biggest variable in whether people rate it five stars or two. Beneath the Streets is unscripted, with each guide writing their own tour, and covers 1890s architecture, the Klondike Gold Rush, Skid Row and the Coast Salish peoples. It is explicitly not a comedy tour and explicitly not a ghost tour.

Why there is a city under the city

On 6 June 1889, a glue pot boiled over in Victor Clairmont’s cabinet shop, in the basement of the Pontius Building on Front Street — First Avenue today. A 24-year-old cabinetmaker’s assistant had been heating glue over a gasoline fire; it caught the wood chips and turpentine on the floor. Seattle was wood-planked streets and wooden buildings served by a private water system that could not hold pressure, and when crews turned to Puget Sound for water, the tide was out. Roughly thirty blocks of downtown burned.

Rebuilding, the city took the chance to fix a drainage problem that had made the old street level miserable — at high tide, the plumbing ran backwards. Streets were regraded a full storey higher, but the new buildings went up before the streets were finished, so for years pedestrians walked at the old level and climbed ladders to cross the road. When the sidewalks were finally decked over, the original storefronts became the passages you now walk through. They were sealed for public use in 1907, during a typhoid scare.

Two details are worth correcting because they circulate widely: the fire did not start in a paint shop, and the 1907 closure was typhoid, not bubonic plague.

You can see a piece of this for free. The amethyst-coloured glass prisms set into Pioneer Square’s sidewalks are the skylights that lit the buried pavements below.

Other experiences you might enjoy

Pioneer Square rewards a bit more time than just the underground — it’s a five-minute walk from the waterfront, Pike Place Market and the ferry terminal, and an easy add-on to a Puget Sound harbor cruise or a downtown Seattle walking or food tour. If you’re building out a longer itinerary, pair the underground with a Space Needle visit or an Argosy harbor cruise for a full day above and below the streets.

What it costs

Bill Speidel’s is $30.00 for an adult at the checkout, with $27.00 for seniors, students and military ID holders, $20.00 for youth aged 7 and up, and $10.00 for children 6 and under. If you have seen $22 quoted elsewhere, that figure is out of date — as is the $26 that some 2026 guides carry.

Beneath the Streets is the one to watch, because its advertised prices exclude tax and 15.35% is added at checkout. That single fact explains why one listing says $26 and another says $32 for the same 60-minute tour. Its own website currently shows two different standard prices, so treat the all-in adult fare as roughly $30 to $31 rather than any single advertised number. Booked through GetYourGuide, the same tour runs from $31, rated 4.6 from 2,471 reviews.

Concession rates are where booking direct genuinely pays: educator and military rates — the military tier covers active, retired or family with ID — exist only on the operator’s own site. One widely repeated claim is wrong, though: under-7s are not free. The ladder bottoms out at $5 for toddlers aged 2 to 6. “Children under 7 are welcome” means welcome, not free.

For a full-fare adult the direct saving is a dollar or two at most, and there is a reason you might give that up. Bill Speidel’s direct policy is no refunds except when it cancels, with no late admission. Beneath the Streets publishes no direct cancellation policy at all, but the same tour carries free cancellation up to 24 hours ahead when booked through GetYourGuide. About a dollar buys you the ability to change your mind.

Walk up, or book ahead?

This is the real decision, and the two operators are opposites.

Bill Speidel’s runs nine departures a day, on the hour from 10am to 6pm, every day of the year except Thanksgiving and Christmas. Tickets are first come, first served and sold at the booth until a tour starts, so a full slot usually means waiting an hour rather than missing out.

There is a wrinkle that costs people tours. From June to September the company adds half-hourly departures — and sells them only at the box office. They do not appear online at all. If you check the website on a July afternoon and see nothing available, there may well be a tour leaving in thirty minutes that only exists at 614 First Avenue.

Beneath the Streets is the reverse. A 25-person cap across a 10am–5pm window is a fraction of that capacity, and its own FAQ says tours often sell out. Here, a sold-out slot frequently means no tour that day. Book it in advance.

Stairs, lighting, and who should skip it

Neither tour is wheelchair accessible. Beneath the Streets counts six flights of stairs with no elevator, and its ticket office is itself below street level down an outdoor staircase. The reason is the buildings: alterations in the Pioneer Square Preservation District need design-review approval, which makes the necessary structural work impracticable rather than merely expensive.

The ground underfoot is uneven, and the lighting is — in the operator’s own words — spotty, with dim stretches falling exactly where the footing is worst. Ceilings drop low enough in places that taller visitors duck. Wear flat, grippy shoes you do not mind getting dusty; the official advice is to leave the heels at home. It is cool and damp down there year-round, so carry a layer even in August. There are no toilets on either route.

For children, permitted is not the same as suitable — and Beneath the Streets says as much itself, noting that children may struggle with an hour of history. Realistically, eight to ten is the floor. Below that, dim light, stairs and a lot of standing still tend to win.

A word on the neighbourhood, since it drives a large share of both tours’ negative reviews: Pioneer Square is Seattle’s oldest and handsomest district, and it is also a focal point for the city’s visible street homelessness and drug use. Both meeting points sit inside that area, and the above-ground portions walk through it.

It is not on any Seattle pass

Neither underground tour is covered by any Seattle attraction pass. The Seattle CityPASS bundles the Space Needle and Aquarium plus three choices from Chihuly, an Argosy harbor cruise, MoPOP, Woodland Park Zoo and the Pacific Science Center — no walking tour of any kind. Seattle C3 covers any three of ten attractions, and the underground is not among them. Go City does not operate in Seattle.

Multi-stop day tours are the one place to read carefully. Some list “admission to Beneath the Streets” and genuinely include the tour; others promise “a taste of the Seattle Underground”, which means an abbreviated look, not the real thing. If the inclusions do not name admission, assume you are not getting it.

After dark, and adults only

Beneath the Streets runs an 18+ After Hours tour of Pioneer Square’s red-light history, at 75 minutes and around $28 before tax, on weekend evenings in peak season. It also runs a Queer Underground History Tour covering the district’s early LGBTQ+ nightlife — the only tour of its kind in the city, monthly in winter and more often through summer.

Bill Speidel’s still runs its Underworld Tour nightly at 8pm and 9pm, at $42.76 with a cocktail included — though you would not know it from the website, which does not list it. If you want it, go through the booking store or call. Its old Paranormal Experience is gone.

Can I do both Seattle Underground tours?

Yes, and it’s not as repetitive as it sounds — Bill Speidel’s and Beneath the Streets hold access to different basements under Pioneer Square, so you see different passageways with each. Book Beneath the Streets in advance since it sells out, then walk up to Bill Speidel’s same-day; the two together run about two and a quarter hours combined.

The bottom line

Turning up on the day, travelling with a group, or after an entertaining hour? Bill Speidel’s. Planning ahead, sensitive to crowds, hard of hearing, or actually there for the history? Beneath the Streets, booked in advance.

If Seattle has thrown a wet afternoon at you, either works — just remember you will be outside for part of it. And if the stairs rule you out, the free Klondike Gold Rush National Historical Park museum two blocks away covers much of the same history at street level, Wednesday to Sunday.
