Eden Falls: trail length and cave access

Eden Falls sits at the end of the Lost Valley Trail, a 2.3-mile round trip rated easy to moderate that also passes a natural bridge and a 200-foot bluff shelter called Cob Cave before reaching the 53-foot falls. Past the falls, Eden Falls Cave adds an unlit, unpaved side trip about 200 feet into the hillside for anyone carrying proper lights and comfortable in tight spaces. It's one of the stops in our waterfalls in Arkansas guide, in the same Buffalo National River cluster as Hemmed-in-Hollow Falls.

The trail

The Lost Valley Trail starts near Ponca and runs 2.3 miles round trip, an easy-to-moderate hike well suited to families, passing a natural bridge and Cob Cave, a 200-foot bluff shelter, before ending at Eden Falls (National Park Service, hike the Lost Valley Trail). There's no fee to enter Buffalo National River and no permit required for the hike.

Past the falls, Eden Falls Cave offers a further, optional detour: about 200 feet into an underground room with its own small waterfall inside. This is a wild cave, unlit and without a marked path. Bring multiple independent light sources if you plan to go in, and turn back if any of them fails.

When to visit

Flow at Eden Falls depends on recent rain, the same as most falls in this part of the Ozarks; it runs best after a good rain event and can slow noticeably during a dry summer stretch. Lost Valley is also one of the park's most frequent search-and-rescue locations, mostly slips on wet rock, per the park's own preventative search-and-rescue guidance (NPS, Preventative Search & Rescue).

How this guide was researched

This page was compiled from National Park Service recreation and safety pages for Buffalo National River's Lost Valley Trail and USGS geographic 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

Wet rock is the main hazard here, both on the approach to the falls and especially inside Eden Falls Cave, where footing is uneven and there's no light beyond what you bring. Watch your step around the natural bridge and Cob Cave too, since the bluff terrain stays damp longer than open trail, and stay on the established trail around the cave entrance rather than scrambling the slopes above it. The Park Service made the same point after a death here: in September 2021 a 16-year-old visitor who had left the trail to climb the steep slope by the Eden Falls Cave entrance fell about 20 feet and died, and the park's release on the incident asked visitors to stay on established trails (National Park Service, Buffalo National River news release, September 2021). See our waterfall safety guide for more on footing near wet rock, and our waterfalls near me map for other hike-in falls on public land.
