War Eagle Valley Loop Trail is a 8.1 mile lightly trafficked loop trail located near Rogers, Arkansas that features a river. The trail is rated as moderate and primarily used for hiking, walking, and birding.
The trail is well-marked by white blazes, and seems to enjoy a lot of use. We saw one other couple hiking, a few bikers, and saw evidence of horses. That said, the trail is not abused. It's well-maintained, and we saw absolutely zero trash. Note that your dog is welcome to accompany you, provided s/he is leashed.
This isn't a feature-rich hike, though there's a nice view of the creek, and what is probably, in winter, a spectacular look at the valley. It's more a long, pleasant, meandering walk in the woods with a wide variety of plant and animal life to enjoy.
If you start the hike from the Townsend trailhead (check the recordings here or the park service website, not the official map above), the hike ends up being almost exactly 7 miles from the parking lot. This trailhead is also where you'd start for the Clifty Creek and Piney Ridge trails. The signage is excellent, don't worry about getting to and staying on the trail you want.
Nice long hike. Watch your trail signs though. Easy to get into another trail.
I think this is the best trail in the Multi Use system. It isn't three miles, it is over six. Significant elevation change between the parking lot and War Eagle Creek, with benches set along the overview, and a very nice trail walk at the level of the river (although not on the river itself). As always, trail maintenance is great. I have done this trail many times, and have never yet met another person on it.
