Be forewarned, this hike is really just a nature trail.
However, it's a nature trail that somehow transports you to the countryside of the midwest - all within Portland city limits.
The drive onto Sauvie Island takes you past fields of crops, over rolling hills and through herds of grazing cattle. Much of Sauvie Island has been designed and managed by the Oregon Department of Fish and Wildlife to support the waterfowl population. Oak Island has long been a rest stop for many migratory birds and as you walk the 3 mile nature loop, you'll be inundated with sounds and songs of birds.
Oak Island is actually a peninsula that is sandwiched between Sturgeon and Steelman lakes. It's a flat, easy stroll that offers pretty lakeside views and lots of waterfowl watching (not to mention cows). Hiking at a mellow pace, I walked the loop in about an hour.
While Oak Island isn't one of the most dramatically beautiful hikes of Oregon, it was a great introduction to Sauvie Island. Don't forget to stop at the convenience store right after you cross the bridge onto Sauvie and pick up a $7 parking pass.
Boot of Choice: Danner Women's Mountain Light II . Since it was early morning, after a week of rain, I needed something waterproof. My Mountain Light II's have a full GORE-TEX liner and were perfect for tromping through the tall wet grass on Oak Island.
