Nisqually National Wildlife Refuge Boardwalk - Nisqually, Washington -- This used to be one of my favorite nature walks in the southern Puget Sound region. I lies just north of Olympia, WA. near Lewis-McCord military installation.
Timothy Lake Loop, Portland, Oregon - mostly flat, stroll around the Lake with breathtaking views of Mt. Hood and beautiful forests. Be sure to get a look at Little Crater Lake, a small artesian pool near the trailhead.
