This is my favorite trail of all I've riden. The trails are marked very well and there are a lot of points where you can get off the trail or join on it to make your own personalized ride. It is easy enough for the not so experienced, but it can be a good ride for the experts as well. Not the most technical or the hardest workout in the world, just moderate, but had to rate it a 10 overall and the goofy rating system wouldn't let me unless i rated the technical aspects a 10. (One side note - no logs or rock gardens or any rooty areas). About 98% single track with a little two track in there. Its a very smooth ride with a bunch of different areas along the trail. You start with mild hills and lots of smooth turns and small elevation changes. It goes into a more open straight away area, then into the climbs. This is a smooth ride with lots of different terrain (being half deciduous and half coniferous). Its got switchbacks, fair climbs, differing types of climbs, smooth terrain, and a great layout. Very beautiful and its free. Perfect fun ride.
Take exit 279 off of I-75 and head north on old 27, you'll be heading into the city of gaylord. You will turn right onto commerce road about 1.5 miles after you exited I-75. I believe this is the second light you will come to, either way Commerce road will be at a light right before Kmart. You will wind down this road past the post office and near an elk viewing area. This road will come to a "dead end" near an apartment complex on the left, but it is quite clear you can keep going straight into the park. This is easy to get to. It only takes about 5 mins to get here from I-75. The trailhead is just before the parking lot and is clearly marked.
