The Rail Trail in Idaho is a great place to take any motorcycle,atv,utv out on. If you have a chance to go to Yellowstone National Parkit is on the way there buy Ashton Idaho. One part of the Trail starts by Ashton ID, and goes North following an old narrow gauge railroad bed.through some beautiful scenery. The surface of the trail is made of cinders from old coal used on the railroad. The trail has historical markers and pictures of what it looked like way back in time. Still one of my favorite places to go on a TW. There are different trails that take off from the main trail that goes to West Yellowstone. I wish Utah had a trail like that. Don't take me wrong,Utah has a lot of great riding outdoors. Just wish they could take some old railbeds and make a main trail system from it.
