The Devil’s Den Self-Guided Trail (Devil’s Den State Park, southern Washington County, Ark.) is one of the coolest state park trails in Arkansas. The rock formations and the seasonal waterfall on this short trail are wonderful.
It’s not a difficult trail. It’s about 1.2 miles long, and there’s not much of an elevation change (about 100 feet).
(At present, the namesake Devil’s Den Cave is closed to the public due to white-nose syndrome.)
The 1.8-mile stretch of Section 1 of the Ouachita Trail from Forest Road 6014 (west end) to the Winding Stair Trailhead is an enjoyable walk. Along with the rest of Section 1, it is on Winding Stair Mountain (Ouachita National Forest, LeFlore County, Oklahoma) one of my favorite places to hike.
This stretch covers the last part of Section 1. The easiest way to reach it as a standalone hike is to start at the Winding Stair Trailhead. (Google Maps directions.) From there you would head west for a little under 2 miles. (Across the highway is the start of Section 2.)
The elevation change on this stretch is about 300 feet, so be prepared for a bit of climbing. It is all on the north side of the mountain. The trail in this part is usually in good condition and not difficult to follow.
The current Lake Fort Smith State Park is fairly new. The original park closed in 2002 due to the enlargement of the reservoir lake. The current park opened in 2008 with all-new campsites, visitor center, cabins, and swimming pool.
Until recently, the only trails at the park were the Warren Hollow Trail and the beginning of the Ozark Highlands Trail. But in the past few years, two new trails have opened: the Boston Mountain Trail (4-mile semi-loop) and the Shepard Springs Trail.
Recently, the Boston Mountain Trail has been expanded with an additional loop. The original loop A is around 4 miles. Loop B is about 2.5 miles. It is open to mountain bikes and hikers.
