Lost Trail National Wildlife Refuge (NWR) is located in the west-central portion of Flathead county in the serene and picturesque mountain drainage known as Pleasant Valley. The Refuge was acquired in August 1999. Prior to acquisition, Refuge lands were privately owned and managed as a cattle and horse ranch known as Lost Trail Ranch. Because the Refuge is relatively new, many public use activities are limited at this time. Refuge policy and regulations require the development of various public use plans before activities can be allowed. These plans will receive public input during the administrative planning process. Public use activities that are currently allowed include hunting, wildlife observation, wildlife photography, and environmental education.

Please be aware that GPS navigation devices may not guide you correctly to the Refuge. The Refuge can be reached by driving west from Kalispell via Highway 2 approximately 20 miles to Marion. Turn right at Marion onto Pleasant Valley Road. After approximately 1.3 miles, the blacktop road will fork - stay right. The blacktop road eventually turns to gravel. Continue on the main gravel road approximately 13 miles. The refuge headquarters will be on the right approximately 4 miles from the east entrance.
