This gentle 1.5-mile loop winds through the breaks above Ash Hollow, passing exposed limestone and sandstone layers rich with ancient fossils. Interpretive signs explain both the geological history and the human story — this was a crucial water stop on the Oregon Trail where travelers carved names into the soft rock. The trail is mostly flat with a few gentle grades, suitable for most fitness levels.
The trailhead sits adjacent to the Ash Hollow Fossil and Visitor Center off Highway 26, about 3 miles southeast of Lewellen. Spring and fall offer the best hiking conditions, though the trail stays open year-round. Bring water and sun protection — shade is minimal once you leave the visitor center area.
