Mad Dog Trail - East Tennessee
Hey folks,
I recently ran this awesome trail in Cherokee National Forest and wanted to share it here for those looking for travel ideas!
(The video of this route will be posted to the onX YouTube channel soon!)
Here's the details:
Mad Dog Trail, also known as Forest Service Road 34 or the “Guardrail Trail” by locals, is one of the more technical routes in Cherokee National Forest. Where most Forest Service Road in this area are graded and groomed gravel routes, this 3 mile long section will give almost anyone a challenge.
Located just outside of Tellico Plains, Tennessee right off of the Cherohala Skyway (Highway 165) this trail can be driven both directions, offering two levels of experience. Entering from the eastern side will give you a 3/10 rating with downhill control and tire placement being the most critical skillsets. But, for the more experienced drivers and capable rigs, entering from the western side takes things up a few notches as you navigate several off-camber sections and rock steps to reach its summit. This is where the trail becomes a 5/10 or higher depending on the weather. Slick Tennessee clay can make this trail nearly impassible in its worst conditions so keep an eye on the sky before tackling the “Mad Dog.”
Since this route is one of the very few challenges in this region, it’s popular with off-roaders, overlanders, and adventure riders hoping to test their mettle. High clearance, quality off-road tires, traction control, and a rear locker will all be called into action along its worst terrain. Be prepared for scratches, or memory marks as we like to call them since it sees little to no maintenance with tight brush and low hanging limbs. Carrying a chainsaw is highly recommended, especially after high wind or storms since this road is frequently blocked by downed trees.
This trail is found within Cherokee National Forest, which spans approximately 655,000 acres across eastern Tennessee and western North Carolina in the southern Appalachian Mountains. It features rugged terrain, diverse hardwood forests, trout-filled streams, and rich biodiversity, offering recreational opportunities such as hiking, camping, and wildlife viewing. Historically, the area served as the ancestral homeland of the Cherokee people for centuries until their forced removal via the Trail of Tears in the 1830s. After decades of logging and degradation, the forest was formally established in 1920 under the Weeks Act of 1911, with its current form consolidated in 1936 through Civilian Conservation Corps restoration efforts. It remains Tennessee’s only national forest and a key site for conservation and public enjoyment.
For this adventure, I used the onX Offroad app to download offline maps at home since cell service can be very sparse. I also located a small staging area 100 yards from the trail entrance since the western side has little space for airing down and would block travelers if you attempted this step on the tight trail. There are also several unofficial spurs branching off from this trail so having the proper data in hand is key to staying on the proper route.
This trail can change rapidly with the weather so stay alert for deep water, washouts, and slick mud after heavy rain. Hardwoods, Rhododendron, and thorn bushes encroach the path so keep an eye on your body panels and roof equipment since it's easy for them to snag vehicles while you’re focused on the trail.
This entire area is rich in travel opportunities so if the trail turns out to be more than your skillset allows, don’t feel disheartened; simply explore the easier routes nearby for beautiful streams, plentiful hiking trails, and historic landmarks hidden under the Appalachian canopy of trees. I used one of these roads (FSR217) to link the route back to pavement so you can get a taste of this landscape from a graded gravel trail with many designated camping sites along its length.
This is one of those routes that will get your adrenaline pumping with some white-knuckle challenges, but then help you unwind as you picnic or camp along its peaceful waters after the excitement.
