Holders of a Pierce County Library card may now check out free passes to visit the Foss Waterway Seaport Museum in Tacoma and the Harbor History Museum in Gig Harbor, bringing to five the number of museums countywide for which the library offers free passes.

Foss Waterway Seaport Museum explores Tacoma’s maritime heritage. Pass holders get free admission for up to two adults and four children under the age of 18. Children 5 and under are always admitted free.

The Harbor History Museum’s exhibits, which include a 65-foot purse seiner, can be toured by pass four people covered by the pass. Children under age 5 are admitted free.

The other museums, all in Tacoma, where the free library-issued pass is accepted are the Museum of Glass (up to two adults and unlimited family members under age 18), Tacoma Art Museum (up to two adults and four children under age 18; children 5 and under are admitted free), and Washington State History Museum (up to two adults and four kids under age 18).

The passes can be checked out on a first-come, first-served basis, for one week at any Pierce County Library System (PCLS) branch. The passes are part of PCLS’ effort to connect and strengthen communities, a spokeswoman said.
