In the mid-1800s, the Hagerman Valley offered a place of respite for emigrants making the grueling journey westward on the Oregon Trail. Today, visitors can find visible wagon ruts along the park road and the Oregon Trail Overlook. The Emigrant Trail is a maintained hiking trail that roughly parallels the old wagon route.

Hikers can travel out and back, or drop a vehicle at one trailhead for a one-way journey. Begin hiking at the Snake River Overlook to hike primarily uphill, or begin at the Oregon Trail Overlook for a more downhill journey.

About these trails

The lines are the National Park Service's public trails layer, the trailheads and the waterfalls, views, peaks and historic places along them the Service's public points of interest, read 2026-10-14 and simplified for the map. The write-ups are the Service's own "things to do", unedited. Heights come from USGS 3DEP through Terrain Tiles on AWS (Mapzen/Tilezen), read along each line and rounded; a short trail on steep ground can be off by a few tens of feet. Closures change: check the park's own site before you go.
