Trans-America Trail — Heber Springs to Harriet via the Ozark National Forest Buffalo River Highlands
The TAT's forgotten Arkansas highland crossing.
The TAT’s Arkansas segment doesn’t get the press of the Smokies or the Rockies, but the stretch from Heber Springs north through the Ozark National Forest to Harriet on the Buffalo River rewards anyone who actually runs it. You’re on Sylamore Creek forest roads, then pushing north through the Boston Mountains on old logging two-tracks with tight tree-line, loose rock shelf road above the river bluffs, and red clay two-track that turns to axle-deep grease after rain. The Buffalo National River valley below is wild and largely roadless — up on the ridge you feel that isolation immediately. Crossings of Sylamore Creek and several unnamed tributaries add real consequence to wet-season runs.
This is a Moderate segment on a dry run; after rain it goes Difficult fast. A high-clearance 4WD or capable dual-sport is the right tool — stock trucks struggle in the clay. The TAT through Arkansas is best ridden or driven April through early June and again September through November. Summer is brutal humidity and storms; winter clay can be impassable. Fuel in Heber Springs and Mountain View. No permits required on national forest portions. Dispersed camping is allowed in the Ozark National Forest. Cell service is spotty to none once you drop off the main highways — download offline Gaia GPS maps and load the TAT GPX before you leave pavement.

Frequently asked questions
Can a stock Jeep Wrangler or 4Runner handle this stretch of the TAT without any mods?
A stock high-clearance 4WD like a Wrangler or 4Runner will get through under normal conditions. Lifted or skid-plated rigs have more margin on the rocky two-tracks and after rain, but bone-stock is doable if you're not pushing it during wet conditions.
What's the trail like in winter — is it passable from December through February?
Technically open, but Ozark winters bring ice, snow, and mud that can shut down the two-tracks fast. April through early June and September through November are the reliable windows — winter runs here are high-risk and not recommended unless you're prepared to self-recover in a remote area.
Do I need a permit to run this segment, and are there any fees?
No permit required to drive the route. Dispersed camping in Ozark National Forest is free and allowed without a permit — just stay 150 feet from water, roads, and trails, and follow Leave No Trace. Check the USFS Ozark-St. Francis site for any temporary closures before you go.
What's the hardest section on this 87-mile run and what makes it technical?
The roughest sections are the narrow eroded two-tracks climbing through the Buffalo River Highlands, particularly after any rainfall when clay-heavy soil turns slick and ruts deepen. The water crossings are generally low-consequence in dry season but can rise quickly after storms — check conditions locally before departure.
How far is the nearest gas station, and can I resupply along the route?
Fill up in Heber Springs before you leave — there's no reliable fuel on the 87-mile stretch to Harriet. The hamlet of Harriet has very limited services, so treat this as a self-supported run and carry extra fuel if your rig drinks more than average.
