Our last hike in Grasslands National Park was the Riverwalk Trail. We took advantage of our pass being valid until 11am to do one last hike the day of our departure. Our guide had recommended this trail as being popular with kids, probably due to the tire swing at the trail head. It was a fairly easy hike through what we more traditionally would have thought of as grasslands. There were some interesting birds but not much other wildlife. Again we saw the small but colorful prairie flowers and lots of tiny blue butterflies. The soundscape would have been quite dramatic, I think, had Delilah not been insistent on “singing” the same word over and over again. I will miss these prairies and the vast expanse of space.
