I actually started just south of the park in a lot by where Bellvue loop trail starts. It was 10.16 miles roundtrip. All concrete, I was pleasantly surprised since all of it is in the country. There is no shade any where along this trail where I was. I hiked over to another parking lot where next time I will start there and go east. This trail runs south of Offit AF base and you can here and see jets taking off. All around it was very pleasant to walk. Very peaceful. Wasn't really alot to take pics of. Your not to far from the Missouri River. I was just looking and to where I will start next time I will have over 21 miles left to the end of the trail. It turns into keystone trail.
