Owen-Putnam State Forest Fire Tower Technical Loop
Fire tower climb with creek crossing technical descent.
The fire tower road climbs 400 feet in less than two miles through Owen-Putnam State Forest, switchbacking up limestone ridges that drop off into deep ravines carved by tributaries of Mill Creek. The abandoned steel tower at the summit once watched for smoke across three counties, but now it’s just a rusty landmark for navigating the maze of old logging roads that spider off the main route. The technical challenge comes on the descent through Rattlesnake Hollow, where the track drops steeply through a series of creek crossings that wash out the roadbed each spring, leaving boulder gardens and off-camber turns that’ll test your line choice.
Difficult rating earns its keep — this isn’t casual Sunday driving. You need 4WD low range for the climbs and controlled descents, plus good ground clearance for the rock sections in the creek beds. Avoid it during spring runoff when the crossings get dangerous, and summer’s best for traction on the clay-over-limestone surface. No permits needed, but the state forest gets busy during deer season. The reward is genuine Indiana backcountry with ridge views stretching toward Brown County, plus solitude that’s hard to find this close to Indianapolis.

Frequently asked questions
Can a stock Jeep Wrangler or 4Runner handle this trail, or do I need a built rig?
A stock 4WD with low range and decent ground clearance can get through, but the rocky ravine descents and creek crossings will test your skid plates. Lockers or aggressive all-terrains are a serious advantage — this isn't a trail to bring a lifted Tacoma on street tires and wing it.
Is the trail accessible in spring or does it turn into a swamp?
Stick to June–October. Spring snowmelt and Indiana rain turns the ravines and creek crossings into deep mud traps, and the forest floor stays saturated well into May. Early spring runs risk getting stuck and tearing up the trail — DNR can pull access if it gets bad enough.
Do I need a permit to run Owen-Putnam, and is there a fee?
No permit required and no entry fee for the state forest. Stay aware of any seasonal closures posted by Indiana DNR — check in.gov/dnr/forestry before you go, especially after heavy rain periods.
What's the hardest section of the loop and what actually makes it technical?
The descent through the ravines after the fire tower is where it gets real — loose rock shelves, off-camber lines, and creek crossing exits with slick embedded rock. The creek itself isn't deep, but the approach and exit angles will hang up a short-wheelbase rig if you're not picking your line carefully.
There's no cell service — how far is the nearest gas and what should I know about camping out there?
Spencer is your last stop for gas, roughly 10–15 minutes from the trailhead — fill up before you go. Dispersed camping is allowed in Owen-Putnam State Forest; no hookups, no facilities, pack everything in and out. Download offline maps before you leave because you will have zero signal the entire time you're in there.
