     PLEASE NOTE: Effective October 25th King County will require proof of Covid-19 vaccination or a negative test to enter our establishment. 


Effective October 25th, King County requires that we see Proof of Covid-19 Vaccination for all tour participants 12 years of age or older.  Links to the King County health order and other helpful information appear at the end of this email.

How will this affect your tour? We request that you arrive 30 minutes before your scheduled tour time so that we can check for proof of Vaccination.  As established by the County, valid forms of verification include:

  • CDC COVID-19 vaccine record card or photo of vaccine card

  • Printed certificate or QR code (available at the end of September) from

  • Other official immunization record from within or outside the U.S., including from your health care provider. A photo or photocopy of this card is also acceptable.


NOTES: The last dose of your vaccination must have been administered 14 days prior to the date of your tour.  Documentation of medical or religious exemptions not accepted.

The following vaccines are accepted for verification and have been authorized by the U.S. Food and Drug Administration (FDA) or World Health Organization (WHO): Pfizer, Moderna, Johnson & Johnson/Janssen, AstraZeneca, Sinopharm-BBIBP, Sinovac, and Novavax. All other COVID-19 vaccines are not accepted.

People who are unvaccinated or cannot prove vaccination status will be required to show proof of a negative COVID-19 test from a testing provider taken in the previous 72 hours. Any type of COVID-19 test administered by a testing provider can be used, however Rapid tests taken without the supervision of a testing provider will NOT be accepted. Testing providers are required to use FDA-authorized or approved COVID-19 tests. (Some examples of types of FDA-approved or authorized tests include: PCR, TMA, NAAT, molecular, antigen, and lateral flow. This is not an exhaustive list.) The negative result must be within the past 72 hours.

Face Coverings are still required for all guests on our tours over the age of 2, even if fully vaccinated.   If you, or any member of your party, is unable to wear a face covering during their tour, we will be unable to tour with you. Younger children (pre-school or early elementary aged) may be unable to wear a mask properly, particularly for an extended period of time.  We urge you to consider this and not purchase tickets if this will be an issue for your child(ren).

We apologize for the complications these new requirements might present and do hope that you will be able to tour with us.
