Lots of trails, both marked and unmarked. Be aware that "Tranquil Trail" is not a tranquil bike ride. It was fun but there arebmany steep hills up and down with MANY roots. Erosion has definitely taken its toll on the trail. Nevertheless, some of the views are breathtaking making all the sweat, profanity and walking your bike up the steeper hills well with it!
Also, coffee trail isn't as good as people say it is. Maybe I just rode it at a bad time but since it is a horse trail there was a lot of loose dirt making it very slow going and frustratingly exhausting.
Overall, if you find yourself on Mackinac Island and want to get explore more of the unpopulated areas, the mtb trails are a great option. Only saw 2 other mtb bikers on the trails and I was riding for about 2 and a 1/2 hours on a busy summer day.
