We have been going yearly to the cabins in Cheboygan State Park for many years and have stayed at each cabin they offer.  All of them are great, vault toilet and hand pump for water, drive up (although the road in can be a little rough).  Some have better beach access then others, 2 of them have firepits on the beach to enjoy the amazing sunsets.  Excellent view of the bridge and many large boats going by, perfect photo opportunity!
