Ozark Highlands Trail

The Ozark Highlands Trail is a 364-km point-to-point trail across the Ozark Mountains of Arkansas, United States, gaining 3,754 m of elevation over a typical 15-day thru-hike. Rated moderate to strenuous, it climbs and drops through rugged sandstone bluffs, hardwood forest and the Buffalo National River corridor, linking the Boston Mountains, Richland Creek Wilderness and Sylamore highlands in one continuous backcountry route.

About the Ozark Highlands Trail

The Ozark Highlands Trail (OHT) is maintained by The Ozark Highlands Trail Association, a volunteer organisation that has built and marked the route since the 1970s with 2-by-6-inch white blazes (blue on the Norfork Lake section). It is classified in HikeLoad's database as a Regional Walking Network (RWN) route — a significant, well-signed regional trail rather than a short local loop. Over its 364 km the trail gains 3,754 m of cumulative elevation, an average of roughly 10 m of climbing per kilometre, which puts it firmly in moderate-to-strenuous territory for a multi-day backpacking trip.

Unlike alpine long-distance trails, the OHT rarely climbs above 700 m, but the terrain is relentlessly undulating: the route crosses one hollow, creek drainage or ridge after another, so daily elevation gain adds up even when the map profile looks modest. The trail runs entirely through the Ozark-St. Francis National Forest and the National Park Service's Buffalo National River corridor in northern Arkansas, threading past sandstone bluffs, waterfalls and some of the largest tracts of contiguous hardwood forest remaining in the interior United States.

The trail's character shifts noticeably as it runs east. The Boston Mountains stretch is the most rugged and remote, with long gaps between road crossings and resupply points, so hikers carry the heaviest food loads here. The Buffalo River section trades ridge walking for a more intimate, canyon-bottom feel as the trail shadows one of the last major undammed rivers in the lower 48 states. The Sylamore section, the gentlest of the three, eases hikers toward a finish near Blanchard Springs with shorter climbs and more frequent water sources. Knowing this shift in advance helps with pacing: the temptation is to front-load big miles early, but the Boston Mountains are exactly where slower going and sparse resupply make that plan backfire.

Point of view worth acting on: walk it west to east, starting at Lake Fort Smith. That is the direction the trail was originally built in, the direction water and most resupply logistics flow, and the direction that saves the most technically difficult, least-maintained tread — the eastern Norfork Lake extension, which still has roughly 18 km of unbuilt cross-country walking and a long road section — for last. For a clean, fully-built singletrack experience that matches a 364 km / 15-day itinerary, most hikers are better off finishing at the Sylamore trailhead near Blanchard Springs rather than pushing on toward Norfork Lake.

Route Overview & Stages

The OHT is built and signed in named sections rather than fixed daily stages, so multi-day itineraries are stitched together from these blocks. The table below uses the Ozark Highlands Trail Association's own published section mileage, converted to kilometres; HikeLoad's GPS-based total of 364 km for the commonly hiked Lake Fort Smith–to–Sylamore route sits close to, but not identical with, the sum of these sections, since OHTA periodically reroutes short stretches around washouts and land access changes.

*Per-section elevation gain is not published stage-by-stage by OHTA; figures above are derived by splitting the trail's total 3,754 m gain proportionally across each section's official mileage.

Most 15-day itineraries average 24.3 km per day, but that number hides real variation — the Richland Creek Wilderness and Buffalo River bluff stretches are noticeably slower per kilometre than the rolling Boston Mountains ridge sections further west, so it pays to plan shorter days around Richland Creek and Big Bluff and bank distance on the smoother Sylamore stretch.

Highlights & Points of Interest

• Lake Fort Smith State Park — the trail's western terminus and the standard start point for a full traverse.
• White Rock Mountain — a rim-top overlook in the Ozark National Forest popular for sunrise views over the Boston Mountains.
• Haw Creek Falls Recreation Area — a maintained camping area with a swimmable creek and waterfall, a natural resupply and rest stop roughly a third of the way along.
• Richland Creek Wilderness — home to Twin Falls, a rare double waterfall that runs strongest after spring rain; consider timing this section for March or April high water.
• Woolum Ford — where the OHT meets the Buffalo River, the boundary between the Boston Mountains and Buffalo River sections.
• Big Bluff — one of the tallest bluffs in the interior United States, towering over the Buffalo River near the Goat Trail.
• Hemmed-in-Hollow Falls — a roughly 64 m seasonal waterfall, often cited as the tallest between the Rocky Mountains and the Appalachians.
• Blanchard Springs Caverns — a National Forest Service show cave near the Sylamore terminus, a fitting finish-line detour before heading home.

Best Time to Hike the Ozark Highlands Trail

According to the trail association, fall through spring is the peak hiking window, and the OHT is well known regionally for winter hiking when higher, snowier trails elsewhere are closed. As of 2026, October remains the single best month to start a full traverse: daytime temperatures typically sit in the 15–21°C range, biting insects and ticks have died back from their summer peak, humidity drops sharply, and hardwood forest across the Boston Mountains turns into fall foliage color roughly mid-to-late month.

Spring (late March–April) is the second-best option and the better choice specifically for waterfall-chasers, since Richland Creek's Twin Falls and Hemmed-in-Hollow both run fullest after spring rain — but expect muddier tread, higher creek crossings and a heavier tick season starting to build. Avoid July and August: Arkansas Ozark summers combine high heat, high humidity and low water in creek-fed sections, making resupply and hydration planning materially harder. Winter (December–February) is hikeable and popular with locals for its solitude and open canopy views, but expect occasional ice on north-facing bluff sections and shorter daylight hours to plan stages around.

Practical Information

Accommodation

There are no huts on the OHT — accommodation on-trail means backcountry camping, either dispersed in the National Forest or at designated sites such as Haw Creek Falls and Gunner Pool Recreation Area, both free or low-cost (typically under €10 per night where a fee applies). Hikers who want a shower and a real bed can detour into small resupply towns along the route — Ozark, Cass, Pindall, Marshall and Mountain View — where basic motel rooms generally run €70–95 per night as of 2026.

Getting There & Back

The western terminus at Lake Fort Smith is roughly a 45-minute drive from Fayetteville's Northwest Arkansas National Airport (XNA), the nearest sizeable regional airport. The eastern Sylamore/Blanchard Springs terminus is more remote — allow roughly 2.5 hours' drive from Little Rock's Bill and Hillary Clinton National Airport (LIT), or about 1.5 hours from XNA via Harrison. Because it is a point-to-point trail, most hikers arrange a car shuttle or drop a second vehicle at the finish; the Ozark Highlands Trail Association's shuttle contact list is the standard resource for this.

Permits & Fees

No permit or trail-use fee is required to hike the OHT. Many trailheads have free self-registration boxes that the Association asks hikers to sign for safety-tracking purposes, and dispersed backcountry camping on National Forest and Buffalo National River land is free. Note that dogs must be leashed where permitted and are prohibited on National Park Service-managed sections of the Buffalo River corridor, and blaze orange is strongly recommended during the fall hunting season that overlaps with the trail's best hiking months.

Gear & Packing List

With 3,754 m of gain spread across rugged, root-strewn Ozark tread, pack weight matters more here than the modest peak elevations suggest. For a 15-day carry between resupply towns, an ultralight framed pack in the 45–65 litre range is the practical sweet spot — something like the Hyperlite Mountain Gear 3400 Windrider (680 g) or the heavier-duty Osprey Aether 65 (2,210 g) if you prefer a traditional suspension system for the longer food carries between towns. Hikers doing shorter 2–4 day sections of the trail can go lighter still with the Hyperlite Mountain Gear Aero 28 (536 g). Base-weight discipline matters on a route this long and humid — see HikeLoad's Best Ultralight Backpacks 2026 roundup for more pack comparisons, and plan food quantities using the calorie guidance in How Many Calories Do You Need Hiking a Full Day?, since resupply gaps of 3–4 days are normal between the trail's small towns.

Beyond the pack itself, prioritise a reliable water filter — creek levels swing hard between spring flood and late-summer trickle — plus a lightweight rain shell for the frequent frontal systems that move through the Ozarks in fall and spring, and a bear-resistant food storage method for the Buffalo River corridor, where black bear activity is well documented. Footwear matters more here than the modest elevations suggest: the tread is frequently rocky, root-crossed and slick after rain, so trail runners with aggressive lugs or a light mid-cut boot both outperform road-running shoes over 364 km. Trekking poles are worth the extra weight too, given how many creek fords and steep, loose descents the Boston Mountains section stacks up before the trail eases off near Sylamore.

Similar Trails You Might Like

Hikers who enjoy the OHT's mix of bluff-line views and canyon-bottom river walking tend to like other United States routes built around dramatic elevation contrast in a short footprint. Worth comparing: the South Kaibab Trail (9 km) and North Kaibab Trail (21 km), both steep rim-to-river descents in the Grand Canyon; Hidden Canyon (2 km) for a short, exposed sandstone scramble; and in the Sierra Nevada, the Clouds Rest Trail (15 km) and Panorama Trail (8 km), both high-reward viewpoint routes above Yosemite Valley. None match the OHT's 364 km length, but all share its combination of significant elevation change per kilometre and standout single-feature payoffs.

Frequently Asked Questions

When is the best time to hike the Ozark Highlands Trail?
October is the best single month as of 2026: temperatures moderate to 15–21°C, ticks and humidity drop off, and fall foliage peaks across the Boston Mountains. Late March through April is the best alternative for waterfall flow, though tread is muddier and creek crossings run higher after spring rain.

How difficult is the Ozark Highlands Trail?
The OHT is moderate to strenuous. It rarely climbs above 700 m, but 3,754 m of cumulative gain over 364 km — about 10 m of climbing per kilometre — comes from constant up-and-down through creek drainages and bluff lines rather than one sustained climb.

How many kilometres per day should I plan?
A 15-day traverse averages 24.3 km per day, but the Richland Creek Wilderness and Buffalo River bluff sections are slower going than the rolling Boston Mountains ridgeline further west, so build shorter days into the itinerary around those two stretches.

Where do you sleep along the Ozark Highlands Trail?
There are no huts on the OHT. Hikers camp at free or low-cost designated sites such as Haw Creek Falls and Gunner Pool, or disperse-camp in the National Forest; small towns along the route offer motel rooms from roughly €70–95 a night for resupply stops.

Do you need a permit to hike the Ozark Highlands Trail?
No. The trail requires no permit or fee. Many trailheads have free self-registration boxes maintained by the Ozark Highlands Trail Association, and backcountry camping on National Forest and Buffalo National River land is free of charge.
