I was curious about this. Are there good (legal) trails on the island besides Turtle Ridge park?If you're going to Mackinaw, Drummond is the best choice! Lots of trails that as long as you have 30s or bigger you can do the majority. The maps are horrible. Shell Beach (I think it's called) is the only thing to see on the north side and is well worth the drive. The Turtle Ridge offroad park would probably be a bit much for you and is more fun with a friend.
