Smithsonian's National Zoo -- 125 Years
A Trail Transformed:
As you walk downhill from here, glimpse through the woods on your right to see the Zoo's other main path, which is also a new exhibit highlight the magnificent wildlife diversity of North America. In 2012, the old Valley Trail became American Trail.
American Trail was designed with sustainability in mind: ozone systems to clean pool water without harsh chemicals; automated controls to save water and reduce energy use; filters to keep water quality high and save thousands of gallons from going down the drain! |
