The Tualatin River National Wildlife Refuge is a small park that contains 1 mile of easy hiking trails in the Winter, and 4 miles in the Spring and Summer. The paths are flat gravel and and will take you through a growing oak savannah, as well as through a small forest, ending at the wetland oberservation deck. There are hundreds of bird species to be seen here, especially in when nesting in the Winter. The Refuge has a newly constructed wildlife center with exhibits, gift shop, and a spotting scope to use. If you’re a fan of birds, its a must see! Really good for kids as well.
