I was traveling through on my way back to Ohio, but I wanted to ride on portions of this trail. I had stayed overnight in Chadron and saw the trail along the road as I drove east. That part was rough looking and not finished as per TrailLink. I never did find a location of a trail head in that area. I stopped in Rushville to see the trail there. The 15 miles between Rushville and Gordon were complete, so the crushed stone was a much better surface. Due to lack of time and not wanting to bike against 25-30 mph winds, I went on to Valentine. I parked in the lot by a grocery store, which was close to the trail. I wasn't sure where else to park in town. I rode the trail to the bridge. While researching this trail, TrailLink had said that the Nicobara Bridge over the Niobrara River was closed, but I was at least hoping to see it. In fact, it was open. It was awesome to see and the views were great. It was a little nerve racking with the winds at 25-30 mph and higher gusts, I felt like I was going to blow over the railing. :-) I went to the parking area on the other side and turned around. I then biked to the trailhead on the west side of Valentine. There is a good ice cream shop on Main Street for those who like to bike to eat treats.
I then drove to Norfolk. The next morning I went to the trailhead there and biked 5 miles out and 5 back. The surface was cement for the first 2 miles, but then changed to crushed stone. Still a good surface. The trail went through the country and along the Elkhorn River.
I did the 2 endpoints, so maybe someday I will ride the middle portion.
