We Started this trail at Conner park off Cantrell then hiked to Walton heights neighborhood where the river trail starts. . Slightly difficult on the way back w steady climbs. But very nice w a creek to cool off and wooded and shady. And it ends at two rivers so you could make it an all day hike by adding the little rock bridges if you felt so inclined.
The entire River Trail is a fun hike to undertake but beware: portions on the Little Rock side are very poorly maintained due to construction. Cutaway from the trail near the LR Amphitheatre (there will be no signs instructing you to do so). Also, when you get near LaHarpe Blvd., take the trail that goes down a street near the railroad tracks: there is no sign, but you can avoid having to walk down Cantrell Blvd. by Dillard's. Overall, it's great to accomplish but there's still many things that could make it more walker/runner/biker friendly. Bring water and prepare for limited access to bathrooms.
It was fairly easy trail with a very pleasant creek flowing beside most of the trail. There was, however, there was a significant number of fallen trees due to the recent storms. Also, I would not recommend the trail shortly after a significant rain. The trail crosses back and forth over the creek several times and any additional water flow could make the crossings very difficult. Also, once you come up into the neighborhood the trail becomes significantly more difficult to follow.
