Pedestrian Underground Concourse

Guys, it’s a glorified hallway. I understand the tendency on Unilocal is to tell everyone how «amazing» this «hidden gem» of a place is, even if it were Guy Fieri’s Times Square restaurant, but this is a purely functional hallway with about 5 pieces of reproduced photographs from the Klondike Gold Rush Historic Park (which you can *actually* see in Pioneer Square). I will say that the lobbies of the Rainier Building and 1 Union Square are somewhat interesting, but a passageway that looks like a failed urban renewal project from 1995 is not.
Don’t waste your time, time that you could spend looking at much more interesting hallways.

I give this place 5 stars… It’s clean, it’s safe, it’s well lighted, it’s warm when it’s cold and cool when it’s hot… You can walk across town. get good coffee at several places. There’s art. there are collections of vintage Seattle photos. there are all sorts of little shops and eateries… and I don’t think it’s ‘secret’. but I’ve never seen it crowded. Add to that if you’re traveling Eastbound you come out right at the back door to the convention center, which is an art museum in itself. A tourist might prefer the street for the sights, the atmosphere or the ‘colorful street characters’, but for commuters like me this is perfect.

Stay warm on your short trip across the ways! Interesting historical pictures and facts! Not advertised as a tunnel at all, we kind of just wandered in and discovered it!

I haven’t visited enough underground tunnels to know if this one deserves 5 stars or not, so let’s work this out, arithmetic-​style!
1 star for keeping me out of the rain, cold, and wind and away from motor traffic and waiting for crosswalk signals.
1 star for neat photos of old-​time Seattle
1 star for a display of upcoming shows from the 5^th Ave
1 star for the convenience store selling cards and snacks.
There are also some little deli type eateries, a salon, and an art gallery, though I haven’t taken advantage of any of them yet. All in all, this is a pretty spiffy way to get from 7^th and Union to 4^th and University without having to set foot outside — always a plus when it comes to dealing with Seattle’s variable weather.

The art in the tunnel is of historical pictures primarily from the Puget Sound Region… and I give it 3 stars. However, the tunnel receives 5 stars for providing a safe, warm, and dry walkway to get to work. The corridor runs from 6^th Avenue all the way down to 4^th Avenue. There are a few eateries, access to the Hilton, and a convenience store. You rock tunnel.
Oh, and to correspond with Shekinah’s S.‘s review, yes, one can access the new Gold’s Gym.

This Underground tunnel gets me from 4^th Avenue to 6^th Avenue One Union Square building during the winter without getting wet. I love it. It could use new carpeting in the tunnel but it’s decent for the most part and if you want to stay dry, take this shortcut.

Not sure what would make the «secret» underground tunnel 5 Stars, but I really am a fan. In addition to enabling me to get from Two Union Square to Rainier Square without going outside, the tunnel also has an art gallery, a historic photo display*, several food shops (
)f, a hair salon and a sundries shop. You may be able to enter the new Gold’s Gym from the tunnel (?), and there’s a shoe shine set up at the Rainier end. The escalators on the Union Square end tend to have lots of issues, but that’s about my only complaint. Word.
* Did you know the University of Washington campus was located downtown until 1895?

Secret?! i think not. ;) Although it can appear rather secretive if you consider walking through it the first time (w/​o knowing it’s a tunnel) and ask yourself upon exiting «I was in an underground tunnel?» Yup. And a super COOL one at that, too. :)
Fine shops, great lunch options, and a jackpot of historic Seattle photos — everything from the early days of dumping Pill Hill fill into Elliot Bay to the early Boeing airplanes.
Downtown? Take a stroll down this tunnel. It begins/​ends in Rainier Square and ends/​begins in One/​Two Union Square. Happy strolling. :)
