The Madison Arm Loop, located northwest of West Yellowstone, is a scenic 20-mile route known for its gentle terrain and beautiful views along the South Fork of the Madison River and the Madison Arm of Hebgen Lake. One of the most relaxing rides in the Yellowstone area, the well-maintained trail offers excellent opportunities for wildlife viewing and is a favorite among families and beginner riders.

In winter, the loop becomes one of the region’s premier snowmobile trails, with wide, groomed paths and easy riding conditions. Nearby, the Horse Butte Loop provides another beginner-friendly adventure, winding along the shores of Hebgen Lake and offering access to some of Montana’s best ice fishing.

During the summer and fall, the Madison Arm Loop is popular for ATV riding, hiking, and mountain biking. The route features stunning lake and mountain scenery and passes near Madison Arm Resort and Marina, where visitors can enjoy boating, camping, and convenient access to the water. Whether exploring on a snowmobile or an off-road vehicle, the Madison Arm Loop offers a relaxing way to experience the beauty of the Greater Yellowstone region.
