Chain O’ Lakes Fox River Timber Access Historic Military Road
Civil War supply road through Chain O' Lakes wetlands
This forgotten military supply road connected Fort Sheridan to lumber operations along the Wisconsin border during the Civil War, when Illinois oak was critical for Union gunboat construction. The route threads between Chain O’ Lakes State Park’s kettle ponds, following high ground through wet prairie and oak savanna that floods seasonally. The original corduroyed sections through Nippersink Marsh still surface after heavy rains, while Fox River crossings at three locations require careful timing with water levels.
Easy to moderate depending on seasonal conditions, passable by stock high-clearance vehicles when dry. Spring flooding can make sections impassable until late May, while fall offers the most reliable access. No permits required for public sections, but several private crossings require landowner permission. You’ll discover remnants of lumber camps and military way stations while experiencing Illinois’ original wetland ecosystem before agricultural drainage changed everything.

Frequently asked questions
Do I need a lifted rig or will my stock SUV handle this?
A stock high-clearance SUV like a 4Runner or Wrangler is fine. The trail is rated easy with dirt and gravel surfaces, but the wetland sections can get soft and rutted, so low-clearance cars and sedans should stay home.
When does this trail turn into a muddy mess?
Spring (March–May) is the worst — snowmelt saturates the wetland areas and the dirt sections hold water badly. Stick to June–October for the most reliable conditions; late summer and fall are the sweet spot.
Do I need a permit or pass to drive this trail?
No permit is required to drive the road itself, but if you're accessing via Chain O' Lakes State Park you'll need an Illinois State Park vehicle sticker — annual or daily pass, available at the park entrance. No fee for the trail itself.
What's the hardest part of this trail and what should I actually expect?
The toughest sections are the low-lying wetland crossings where the road surface gets soft and can have standing water after rain. Nothing technical — no rock crawling, no steep grades — but a soft bog can swallow an unprepared 2WD vehicle quickly if you're not paying attention.
Are there places to camp along or near this trail, or is it a day-use-only run?
Chain O' Lakes State Park has a campground near the trail with electric and non-electric sites — book through the Illinois DNR reservation system ahead of time, especially on summer weekends. No dispersed camping on the trail corridor itself.
