Northwest Stream Center is located on a beautiful 20-acre site leased from Snohomish County Parks and Recreation in McCollum Park approximately 1/2 mile east of Interstate 5 between Seattle and Everett, WA. Two salmon streams flow on the grounds that are covered with complex wetland systems and pockets of upland old second growth forest. The Northwest Stream Center includes a 1/2 mile universally accessible Nature Walk past a Trout Stream Exhibit where you can see trout, crayfish, sculpin and fresh water mussels. Then you will go onto an incredible Elevated Nature Trail trail that winds through 20 acres, three feet above the forest floor and surrounding wetlands learning all about NW ecology along the way.
