Smith Falls State Park in NE is a good stop over while floating on the river. An awesome waterfall to hike to and some interesting roads to drive in on. Not good for RV’s unless you have 4 wheel drive and a high clearance type camper. This is the typical basic campground. There was a group present on a float trip and I learned that this is the highest waterfall in NE, which just goes to show how flat the state is :) Seeiously though it is worth a look.
