Four Rivers Field Office

The Four Rivers Field Office, located in southwest Idaho, manages approximately 1.3 million acres of public lands. Here you will find a multiple-use landscape that includes world-class trail and river recreation opportunities, timber production, livestock grazing, and protected areas for rare and endangered wild plants and animals. The 190-mile Ridge to Rivers Trail System, including the Hulls Gulch National Recreation Trail, provides hiking and biking opportunities in the Boise Foothills. Wild horses can be seen within the Four Mile herd management area north of Emmett.

COVID-19 Updates

BLM Idaho Offices are open for in-person visits. Masking requirements vary by location. The BLM has updated its masking guidelines to align with the CDC’s new COVID-19 Community Level tool. This CDC guidance helps communities decide what prevention steps to take. Individuals who are not required to wear a mask are still welcome to do so if they choose. Learn more about the BLM's COVID-19 response here. 

Please stay home if you have symptoms of COVID-19. If you are unable to visit in person, we will be happy to assist you over the phone or via email. Contact us here.
