Hemmed-in Hollow Falls is a waterfall in Newton County, Arkansas. It lies in or next to Buffalo National River, so park hours, fees and rules apply. It sits roughly 25 km (16 mi) SW of Harrison.
Hemmed-In-Hollow Falls is a single-drop waterfall located within the Ponca Wilderness Area of the Buffalo National River in northern Arkansas. The height of the falls is 209 feet (64 meters). According to the National Park Service, it is the "tallest waterfall between the Rockies and the Appalachians." The waterfall is located in Hemmed-In Hollow, a small valley closed in on three sides by 200-foot (61 m) bluffs. The area can be accessed from at least three different hiking trails; Centerpoint Trailhead and Compton Trailhead along State Highway 43 north of Ponca are probably the best choices for those wanting to park and hike in. Of the two, the latter offers the most direct access. From Compton the falls are 2.5 miles (4.0 km) from the trailhead, and the route is usually well marked and well maintained, though the hike out of Hemmed-In-Hollow is notoriously steep and difficult.

Golden hour & blue hour by month
Waterfalls photograph best in soft, even light: overcast days, deep shade, or the hour after sunrise before direct sun hits the water. Bright sun on white water blows highlights and adds harsh contrast.

Milky Way & night sky
From Hemmed-in Hollow Falls, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 5.7 hours on a moonless night), and the core peaks around 25° above the southern horizon. Our light-pollution model puts the sky at about Bortle 2 (typical truly dark site), which is excellent for astrophotography.

Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 42% average cloud cover) and February as the cloudiest (62%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this waterfall
- Look for a foreground: a mossy boulder, a fallen log or the creek's leading lines make a stronger frame than the falls alone.
- Keep a microfiber cloth handy — spray drifts onto the lens, especially at the plunge pool.
- Bracket shutter speeds: 1/8 s, 1/2 s and 2 s give very different water textures and you can choose later.
- A 3-stop ND filter lets you use slow shutter speeds even when the light is bright.
- Shoot a vertical and a horizontal frame; tall falls often work better in portrait orientation.
- Bring a spare battery — cold weather and long exposures drain them fast.
Season: Peak flow is usually in late spring; autumn adds color around the falls, and winter can bring ice formations at colder locations.
Suggested gear: Tripod, Circular polarizer, 3–6 stop ND filter, Lens cloth, Waterproof footwear. Work out exposures with the depth of field, ND filter and NPF rule calculators.
Permits, drones & access
National Park Service rules. Under federal law (54 U.S.C. 100905), still photography in National Park Service areas needs a permit only when it (1) takes place where members of the public are not allowed, (2) uses models, sets or props that are not part of the location's natural or cultural resources or administrative facilities, or (3) would cause the park to incur additional administrative costs to monitor the activity. Ordinary visitor and most landscape photography needs no permit. Commercial filming rules are separate and have changed in recent years — confirm current requirements with the park before a paid shoot.
Drones: Launching, landing or operating unmanned aircraft (drones) is prohibited in National Park Service units under a 2014 Superintendent's closure (36 CFR 1.5), except where a park has issued specific written approval. Flying from outside the boundary over park land can also violate park rules and disturb wildlife.
