There are so many choices for walking here in Bothell. Yesterday we started at the foot bridge by the house icon in the upper right corner of the map. We walked along the river down to Heritage Park. We crossed another bridge before reaching Blyth Park, and went through the tunnel under 96th Ave. The photos are of that tunnel, a view from a small bridge by the river bend in the park, and further up the valley near the bottom left in the map. Yesterday's walk took a little over 1 1/2 hrs RT.
