Flint Hills Military Road
WWI military supply road through tallgrass country
This forgotten military road once connected Fort Riley to Camp Funston during WWI, cutting straight through the heart of the Flint Hills. The two-track follows original survey lines across native tallgrass prairie broken by limestone ledges and seasonal creek crossings. Turkey Creek Ford remains the route’s most challenging feature—a rocky bottom crossing that can run knee-deep after spring rains or turn into a muddy bog during dry spells.
Moderate difficulty requires high-clearance 4WD for creek crossings and rocky sections, though stock vehicles can handle most of the route in dry conditions. Avoid during wet weather when the clay-based soils turn to axle-deep gumbo. Spring wildflowers and fall colors make this route spectacular, but summer heat can be brutal with no shade. Private land borders much of the route, so stick to established tracks. This is pure Kansas—endless prairie horizons interrupted by limestone bluffs and the ghosts of military history.

Frequently asked questions
Can a stock Jeep Wrangler handle Flint Hills Military Road?
Yes, a stock Wrangler will do fine. The trail requires high-clearance 4WD for rocky limestone sections and creek crossings, but nothing extreme.
Is the trail passable after heavy rains?
Avoid this trail during and immediately after heavy rains. The dirt surface becomes muddy and slippery, and water crossings can become dangerous.
Do I need permits to drive Flint Hills Military Road?
No permits required, but portions cross private land with implied consent. Stay on the designated route and respect posted boundaries.
What's the hardest part of this trail?
The limestone rock gardens in the middle sections require careful tire placement and can scrape low vehicles. Take it slow through these areas.
How many water crossings should I expect?
There are 3-4 creek crossings depending on seasonal flow. Most are shallow rock-bottom crossings, but check depth before entering during spring runoff.
