The Jackson-Frazier Wetland is a small protected wetland area in North Corvallis. A boardwalk has been built that runs throughout the wetland in about a 2/3 mile loop. The boardwalk allows you stay dry but get a close up view of this unique environment.
The wetland is home to varied wildlife, and you are sure to hear the whistle of the red-winged blackbird throughout the walk. On sunny days, expect to see dozens of small but harmless snakes sunning themselves on the boardwalk. It is also common to see nutria, the less-shy cousin of the beaver.
If you are interested in wetlands, this is a great choice in the Corvallis area. Expect to spend about an hour on the paths. For more information see the Benton County site.
