The Nall Avenue Path is a paved sidepath along Nall Avenue, its namesake. The path offers connections to the residents of the Overland Park community. The path provides access to apartments, houses, commercial centers, as well as religious and medical facilities. At its north end it connects with the Indian Creek Bike/Hike Trail. Further to the south it connects with the Tomahawk Creek Trail and the 133rd Street Path. Visit the Kansas RecFinder
for more information.
Unless, I missed something significant, it seems to be the sidewalk on Nall. That's not a trail.
