Super easy, if you can get around the sand bars. Watch for rippled waters, and steer far away. An easy, 2-3 mph flow makes for a great beginner afternoon. Just completed this float the first of October. Great afternoon experience.
National Forest has camping, and full hook-up sites.
State Park fees required to enter park for camping/facilities, but no fees for river. Follow NE water boating regs.
Take Nebraska Highway 2 to Halsey National Forest.
Put in at the bridge at the entrance to Halsey National Forest. Took out 4 miles down river, just past Dunning gas station.
