Northwest Trek Wildlife Park is a treasure for wildlife enthusiasts. The signature tram tour through the 435-acre free-roaming area offers the opportunity to spot different species of animals as they wander through forests, wetlands and meadows. In the core walking-tour area, visitors can get a peek at native wild canines and cats as well as forest and wetland critters. The 723-acre park has a little bit of everything: lakes, trails, meadows and plenty of animals. Located near Mount Rainier in Washington state just south of Seattle and Tacoma, Northwest Trek is home to more than 200 North American animals representing more than 30 species.
