Route Information
Leaving the Bolton access don’t miss the magnificent wooded bluffs on the Nebraska side.  You can see Pumpkin Hill and Indian Hill.  The Ponca State Park access will soon appear and it has much to offer.  It has hiking trails, managed prairie with native plants, a chance to identify the trees, cabins, even a bookstore in the Visitor’s Center. It is the last stop before the wide, island filled, and meandering river is transformed into a narrow fast flowing channel. More...
