The 135 mile Arrowhead State Trail is a multipurpose, snowmobile, ski, hiking, mountain biking, sled dog, horseback riding and ATV trail extending from International Falls, MN to the intersection with the Hwy 77 on Lake Vermillion (near Tower). The natural surface trail is used primarily for snowmobiling. For the most part, it follows parallel to U.S. Highway 53. The trail is wide, well groomed and extremely well marked at every intersection with brown State trail signs. It crosses many roads and ski trails near International Falls and again south of the town of Orr.
Approximately 69 miles of the trail are suitable for horseback riding, mountain biking and hiking in the summer, however there may be wet areas. The trail is relatively flat between International Falls and the Ash River. This northern portion of the trail goes through a number of areas that have standing water in the summer which makes this section of the trail mostly suited to winter use. In the winter, you may see moose or wolf tracks on the trail, as well as other wildlife such as deer, lynx, fox and snowshoe hare. There are few cross roads on this section of the trail. After about travelling about 7 miles you will encounter the first trailside shelter. After that, a shelter will be about every 12 miles with longest between shelters of 23 miles.

The southern part of the Arrowhead is very different from the northern part. It features rugged, rolling hills with numerous lakes and streams. At about midway (about mile 69), northeast of the town of Orr, the racers may follow signs pointing to a shortcut across Elephant Lake on the snowmobile trail to the checkpoint at MelGeorge's Elephant Lake Resort , located about 14 miles northeast of Orr on the South side of the lake, off Highway 180.
Many of the hills south of Orr have large areas of exposed rock and enormous boulders, leftovers of mountain ranges worn down by glacial erosion. The areas of bedrock formation known as the Canadian Shield have some of the oldest volcanic rock on earth. There are scenic vistas overlooking the lakes and old iron ore mines. This part of the trail is rugged and heavily timbered with a mix of hardwoods and conifers. There are snowy owl, osprey and bald eagle nests along the trail.
