Can I Wear High Heels?

Be prepared for the Underground to be moderately rugged. You’ll encounter flights of stairs, uneven terrain and spotty lighting. So dress for the weather and leave those high heels at home.

Can I reserve a spot on the Underground Tour?

You can buy your ticket in advance—online or by phone— up to two hours before the start of a tour. Call 206-682-4646. You also may purchase tickets in person at our ticket booth before your tour. It’s first come, first served, so we suggest you arrive early.

Can I get something to eat or drink before or after the tour?

Don’t go hungry, for heaven’s sake. We have quick, fresh fare at Doc Maynard's Public House restaurant and bar, at 614 1st Avenue, next to ticketing. If you’re looking for a refreshing drink, try the best Bloody Mary in Pioneer Square, or local beers on tap, at our full bar!

Where do I park?

Don’t! Please take the bus or light rail (metro.kingcounty.gov). But if you really want to drive, there is parking available throughout the neighborhood both on the street and in parking garages. Click Here for a Parking Map.

Do I have to pay cash for the tour?

We accept credit cards online, over the phone and at our box office.

How many tickets can I buy?

As many as you want, depending on availability, of course. If your group is larger than 10 adults, or has a significant number of children or students, you can have the Underground all to yourself on a private tour. Please contact us at 206-682-4646, ext. 118, to speak with a sales representative.
