Collar Peak rises within the Judith Mountains near Lewistown, Montana, offering a rugged day-hiking destination managed by the Bureau of Land Management. The main attraction is the Collar Peak Trail, a roughly 5-mile loop that traverses varied terrain with scenic mountain views. Hikers can extend their outing by connecting to the Girl Scout Camp Trail, which branches south and follows Collar Gulch Creek through forested drainage.

Wildlife viewing opportunities are strong in this area, with the Judith Mountains supporting deer, elk, and various bird species. Be prepared for some trail obstacles—sections have sustained damage from downed timber and flood washouts, so sturdy footwear and route-finding skills are helpful.

As BLM land, dispersed camping is generally permitted outside of any posted restrictions, making this a solid option for self-sufficient campers seeking solitude. There are no developed campgrounds or facilities on-site, so pack accordingly with water, supplies, and Leave No Trace essentials.

Access roads can be rough and may require high-clearance vehicles, particularly after wet weather. Late spring through early fall provides the most reliable conditions for hiking and camping.
