I have not found a great mapping system that has all of the AR trails as of yet. At mill creek you can use mapplets - it is basically a geo referenced map that will show your position. Note they only have the legal trails on there. Buckhorn has their own map that is maintained very well

Lifetime trail maps have Mac pines / Moccasin Gap trails. The most up to date maps for AR are suppose to be the MVUM map put out by the forest service but that only happens once a year.
So it in not all in a convenient place to get to that I have found yet.
