Point Defiance Zoo and Aquarium
5400 N Pearl Street
Tacoma, WA 98407
This is the northwest's only combined zoo and aquarium. What makes this especially cool is that it gives you the chance to visit a wide range of animals in one location. The zoo has a number of different activities that take place during the day and during the holidays they light up the place with Zoo Lights.
Hours can change monthly. Check their site.
