Overview
The Ohio River Bluffs Trail runs for 5 miles along the limestone bluffs that define the southern edge of Shawnee National Forest. The Ohio River below is one of the largest rivers in North America nearly half a mile wide at this point and the views from the bluff edge are genuinely impressive. Barge traffic moves constantly upstream and downstream. The Kentucky hills are visible on the far shore. In winter, bald eagles congregate along the river in numbers, making this a well-known raptor-watching location.
This is one of the less-traveled trails in the forest, partly because the trailhead is unmarked and the trail itself receives less maintenance than the popular recreation areas. That lower profile is part of the appeal. The bluff top provides solitude and views that the more popular sites rarely offer, and the ecological diversity along the bluff edge limestone-adapted plants, raptor perches, river-corridor vegetation rewards attention.
At 400 feet of elevation gain over 5 miles, this is an easy-moderate trail. The elevation is mostly in the initial climb to the bluff top from the parking area; the bluff-top walk is relatively level.
The Route
Miles 0 to 1: From the Highway 146 trailhead pull-off, the trail climbs to the bluff top through a mix of cedar, oak, and redbud. The first overlook view of the Ohio River appears approximately 0.8 miles into the trail.
Miles 1 to 3: The bluff top section follows the river east with periodic views. The most dramatic overlooks are in this section, with the sheer limestone edge dropping to the river bank below. The forest here is dominated by chinkapin oak and post oak.
Miles 3 to 5 (return): The turnaround point is at a secondary forest road. Return on the same path.
When to Visit
November through March for bald eagles and clear views with leafless trees. April through June for spring migration this river corridor is one of the better warbler migration spots in Illinois. Fall color in October. Summer is hikeable but hot and the dense leaf cover limits views. Check conditions before visiting.
What to Bring
- Many hikers carry 1.5 liters for this length of trail. No water sources available. Individual needs vary.
- Binoculars: the river views and wildlife watching are much enhanced
- Sturdy footwear for limestone sections and unmarked trail
- Tick repellent from April through October
- Compass or downloaded GPS track the trail is not well-signed
Practical Details
No facilities at the trailhead. No fee (as of 2026). Follow Leave No Trace principles. Stay well back from the cliff edge. The drop is abrupt and the limestone edge is uneven.
Getting There
From Elizabethtown, Illinois, take State Highway 146 east approximately 10 miles. Watch for a small Forest Service trailhead sign and gravel pull-off on the south (river) side of the road. GPS coordinates are approximately 37.38°N, 88.45°W. The Harrisburg Ranger District can confirm current trailhead location.
