Really cool tour and site. Seattle has a lot of glass cubes in the sidewalk near the underground and if you look down at some of the glass you can see former parts of the underground that are now used as sewer systems, subway ventilation, and storage areas. Pretty cool.

I have been to one of the entrances to the tunnels, and I can say this is a truly interesting site. Wish I could have gone in, but the tour company was closed that day.

This location is near a local mountain bike trail, so be respectful of your surroundings and make sure to yield to any bikers

This is now demolished. The only part of it still surviving is the runway which is being used by the local airport
