South Fork Madison Road (478)

This is a well-maintained Forest Service Road that joins Highway 20 just west of West Yellowstone and runs to the Idaho Border. At Reas Pass, you can explore Two Tops if your machine is 50 inches or less. There is also a restroom facility at this point. For those who enjoy biking or hiking, there is access to the new paved path being constructed between Big Springs and West Yellowstone. Along the road, you will run along the Madison River headwaters. This is an extremely beautiful stream with opportunities to pull off for a picnic or short hike. This area does have a bear population, so be sure you take precautions to keep everyone safe.
