Hemmed-In-Hollow Falls — 209ft Plunge in Arkansas

Hemmed-In-Hollow Falls is a 209-foot plunge waterfall in Newton County, Arkansas, reached by a strenuous backcountry trek over 5.5 miles.

Hemmed-In-Hollow Falls is the tallest waterfall between the Rocky Mountains and the Appalachians — a 209-foot ribbon of water that drops straight down into a horseshoe-shaped natural amphitheater carved into the Boxley Valley sandstone of the Buffalo National River area in northern Arkansas. The falls flow only during wet months (typically November-May) and dry to nothing by mid-summer. The 5.5-mile round-trip from the Compton Trailhead is genuinely strenuous — steep descent into the hollow, slick rock, 1,300 feet of elevation change. It's the marquee Buffalo National River backcountry day-hike.

What to expect

Drive to the Compton Trailhead (off Highway 21 north of Boxley Valley) — the most popular access. Hike 2.75 miles down a steep trail with switchbacks and rock scrambles. The amphitheater opens dramatically as you arrive — you can walk under and behind the falls when flow is moderate. Water shoes recommended; you'll cross creeks. The hike back up is the hard part. Plan 4-6 hours total. Pair with a Buffalo River float trip in spring.
