Hagerman Fossil Beds National Monument, the Oregon Trail
in Idaho · centroid 87 mi from Boise
The southern route of the Oregon Trail passes through Hagerman Fossil Beds National Monument . This southern Idaho route was typically hot, dry, and dusty and exhausted travelers. Stopping at the Snake River made for a welcome respite.
However, the volcanic geology found in this part of Idaho makes getting to the river difficult. Fortunately, the southern part of what is now Hagerman Fossil beds is made of sedimentary rocks, which not only preserved the monument's famous fossils, but also allowed emigrants on the Oregon Trail to access the river. For information about viewing the Oregon Trail and other features in the monument, stop by the park's visitor center in the town of Hagerman.
There, get the latest information, see an introductory movie, view fossils up close, and obtain maps and information about what there is to see and do in the area. Site Information Location 17970 US Hwy 30, Hagerman Idaho Safety Considerations More Site Information Oregon National Historic Trail

Plan your hike
Maps + permits: long-distance trails like this often require permits for through-hiking, backcountry camping, or specific sections (especially in National Parks). Check with the maintaining organisation listed above and the relevant land manager before booking travel.
Water + supplies: water sources vary seasonally on most U.S. trails. Carry a filter and consult current trail-condition reports — through-hiker journals (PCT-L, AT Reddit, etc.) and the maintaining organisation publish regular updates.
When to go: hiking seasons vary widely with elevation, latitude, and snowpack. Through-hikers traditionally start the AT in March-April (Springer northbound) and the PCT in late April (Campo northbound). High-elevation western trails (CDT, JMT, Wonderland) generally aren't passable until July.
