Welcome to the Idaho Chapter of the Oregon-California Trails Association
We are a volunteer organization dedicated to the preservation and enjoyment of emigrant trails which crossed the western United States to the Pacific Ocean from 1841–1869.
The IOCTA organization is dedicated to education about, preservation, and enjoyment of the emigrant trails through Idaho. Primary activities are trail marking in conjunction with the Bureau of Land Management, National Park Service, and US Forest Service, and trail outings where knowledgeable members lead expeditions on trail segments. Planning and business meetings are held a few times a year.
Many of the members of IOCTA have a wealth of knowledge about the Oregon Trail. Some have spent many years exploring and researching the emigrant trails. Several are published authors of books about the trail.
All people interested in the history of the emigrant trails through Idaho are encouraged to participate. Come join us to share some history and build some friendships on the trails across Idaho! Outings are free and everyone is welcome.
