Michaux State Forest Old Forge Road
Colonial iron routes through furnace ruins
The Old Forge Road winds through the remnants of Pennsylvania’s 18th-century iron empire, where charcoal furnaces once fed the Continental Army’s cannon foundries. Starting near Pine Grove Furnace State Park, this rocky double-track follows the original hauling route past crumbling stone furnace foundations and overgrown slag heaps. The trail’s signature challenge comes at Mountain Creek crossing, where bedrock shelves create a technical drop requiring careful line selection and momentum control through knee-deep pools.
Moderate difficulty demands high-clearance 4WD with skid plates for the jagged shale and creek crossings. Spring brings the nastiest mud and highest water, while fall offers the clearest passage and best foliage. No permits needed, but camping requires designated sites within state forest boundaries. The payoff is pure Pennsylvania history—rolling through landscapes where colonial industry carved the backbone of American independence.

Frequently asked questions
Can a stock Jeep Wrangler or 4Runner run Old Forge Road without modifications?
A stock high-clearance 4WD with skid plates will handle it, but rock sections and creek crossings make skid plates non-negotiable. Lifted rigs have more margin; stock trucks in good mechanical shape get through fine with a careful driver.
When does Old Forge Road open and close seasonally?
September through November is the sweet spot — foliage, firm ground, and manageable water levels. Spring brings deep mud and high creek crossings from snowmelt; summer is passable but buggy and wet. Winter access depends on snowfall and DCNR closures, so call ahead if you're going December through March.
Do you need a permit to drive or camp in Michaux State Forest?
No permit is required to drive the trail. Dispersed camping is allowed on state forest land under Pennsylvania DCNR rules — no fee, no reservation, but you must camp at least 25 feet from water and 200 feet from roads and trails.
What's the hardest section and what should I actually expect?
The creek crossings are where rigs get sorted out — water depth varies with recent rain, and rocky creek beds can hang up low-slung vehicles fast. The embedded rock on the uphill dirt sections also demands slow, deliberate tire placement. Nothing here requires a winch on a dry week, but a wet weekend changes the math quickly.
How far is the nearest gas from the trailhead, and is there cell service on trail?
Gardners is a blink-and-miss-it town with no gas — fuel up in Carlisle (about 15 miles east) or Chambersburg (roughly 20 miles west) before you head in. Cell service is spotty to nonexistent through most of the route, so download offline maps and don't count on a signal for navigation or emergencies.
