Hemmed-in-Hollow Falls: hike length and difficulty

Hemmed-in-Hollow Falls is the tallest waterfall between the Rocky Mountains and the Appalachians at 209 feet, but getting to it is the real story: a roughly 3-mile hike one way from either the Compton or Centerpoint trailhead, with about 1,400 feet of elevation change and a Park Service warning to plan on the entire day. It runs full only after a good stretch of rain, so timing matters as much as fitness. It's one of the stops in our waterfalls in Arkansas guide, alongside roadside falls that need no hike at all; for other states, start from the waterfalls near me map.

Trail and access

Two trailheads reach Hemmed-in-Hollow, both off Highway 43 north of Ponca in the Ponca Wilderness section of Buffalo National River: Compton and Centerpoint. From Compton the trail drops nearly 1,400 feet down the mountainside to the sandstone bluffs along the Buffalo River, then climbs all of it back out; the Park Service describes the route as extremely steep and strenuous and tells visitors to plan on the entire day (National Park Service, hike to Hemmed-in-Hollow, last updated March 9, 2026). The Centerpoint route is not quite as steep, per the same page, but it's a similar distance and still a full-day hike. There's no entrance fee for Buffalo National River, and no permit is required for this hike.

Carry a detailed topographic map. Trail junctions inside the Ponca Wilderness are easy to confuse, and NPS calls this out specifically for this hike. The return climb, after an already long outbound leg, is where most visitors underestimate the effort.

The falls and when to go

At 209 feet, Hemmed-in-Hollow drops into a hollow enclosed on three sides by 200-foot bluffs, a setting that gives the falls its name. It only runs at full flow after a substantial rain event upstream; during dry stretches, especially by late summer, it can thin to a trickle. Late winter through spring, when rain is most frequent, and the days following a fall storm system tend to be the most reliable windows for seeing it running.

This is also the single most frequent search-and-rescue location in the entire park, according to the National Park Service's own preventative safety data (NPS, Preventative Search & Rescue, Buffalo National River). That statistic reflects the trail's difficulty more than any hazard at the falls themselves: steep, loose footing and the length of the hike catch hikers who arrive under-prepared or push on past the point where turning back would be the safer call.

How this guide was researched

This page was compiled from National Park Service recreation and safety pages for Buffalo National River and USGS topographic data. We haven't visited this site ourselves. Trail conditions and flow depend on recent weather; verify current conditions with Buffalo National River before you go. Last checked September 2026.

Before you go

Check the recent rainfall in the area before committing to the hike if seeing water is the goal; a dry week can mean a disappointing trickle after 6 miles round trip. Bring more water than feels necessary and boots with real ankle support, and start early enough to finish the return climb with daylight to spare. Cell service in the hollow is unreliable, so tell someone your plan before you go.

The terrain, not the waterfall itself, is what sends the most hikers home with an NPS rescue team. Watch your footing on the descent and especially on the climb back out, when fatigue sets in. At the falls, stay off the wet rock at the base and away from the lip of the bluffs above; sandstone here is slick when wet. See our waterfall safety guide for more on reading conditions before you go, particularly around wet rock and fast-changing creek levels.
