Just be warned, on the weekends the trails get crowded. Best to take a day or two off work and come up on a weekday. The trails are smoother on the weekdays too (less traffic). Been snowing pretty heavy these last few days, lots and lots of fresh snow.
You don't get any closer to the trails than Ranch Rudolf . Be warned, it's a very popular spot and may already be booked solid for the season. They are right on the trail (literally), and from the Ranch you can go to Kalkaska, Traverse City, Kingsley, or Fife Lake with ease.
