About the Bitterroot Trail Preservation Alliance

The Bitterroot Trail Preservation Alliance (BTPA) was established in 2016. Our goal is to promote and maintain public multi-use non-motorized trails in the Bitterroot Valley. The current Bitterroot Trail is a 45-mile paved trail that connects Missoula, MT to Hamilton, MT – and the welcoming towns along the way – while paralleling the rugged Bitterroot Mountains (see our Interactive Map). In order to maintain this welcoming atmosphere, we ask that all trail users respect adjacent private property and other trail users. 

The BTPA recognizes the significance of preserving and restoring the National Historic Transportation Route along the Bitterroot Corridor. The BTPA is currently working with Government agencies, non-profit organizations, private groups and individual landowners to protect and restore this transportation link. This non-motorized trail connects the Greater Missoula area with unlimited recreation opportunities within a one day’s ride of Downtown Missoula. The Bitterroot Trail happens to parallel and follow the routes of the Lewis and Clark and Nez Perce National Historic Trails as well as the Ice Age Floods National Geologic Trail and the Bitterroot River.

The Board of Directors of the BTPA is drawn from Bitterroot Valley residents who promote and use non-motorized facilities, local community officials, and leaders of regional organizations that encourage sustainable community development.

All funds collected are put directly into trail promotion, signage, and maintenance. With your help and support, the Bitterroot Trail will continue to be a treasure and provide economic development to the communities along the trail.
