Nebraska's newest state park straddles the Niobrara National Scenic River, 18 miles east of Valentine. The park protects the biological and scenic significance of the location, while allowing the public to view the state's highest waterfall. The area primarily serves day-use visitors, canoers on the Niobrara River and canoe campers.
Absolute must stop if traveling through north border of Nebraska. We stopped on way to Black Hills/Rushmore area before heading west to Yellowstone. Went as a kid, falls still looked the same, but it was a lonely dirt trail back then only accessible by boat. Great memories, completely commercialized now, but one of Nebraska's coolest areas to see.
I was at Smith Falls this spring, May 2015. I thought the hike was easy. I like the wood deck leading to the falls. It provides an easy pathway for those who might not otherwise be able to get back in to the falls. The park and grounds around the area were very nice. I enjoyed the river running through as well.
