The Rockport area is state land and is open to the public. The area is in the process of changing management from Forest Mineral and Fire Management Division to Parks Division of the Michigan Department of Natural Resources. This change may make the sinkholes more accessible. The area contains over a dozen sinkholes several contain water, the largest is over 40 feet deep. The trail into the largest sinkhole is adjacent to many of the larger sinks. This group is in a line from the Shoe Pack sinkholes 30 to 40 miles to the west to the sinks submerged in Lake Huron. The Michigan Karst Conservancy has purchased tracts of land that have some real nice sinks, this group is involved in protecting these gems. In the past some of these sinkholes were turned into land fills contaminating the soil and water associated with these sinks.
Getting to this group of sinkholes will require walking over one mile on an unmarked trails. Travel along the east side of the old quarry at the north end a trail will run parallel to the quarry eventually this trail will come out to a power line turn right go about 200 yards and take the trail to the left into the woods. This trail is narrow and will take you along several sinks, one more turn, to the right will take you to the largest sinkhole. These directions and a GPS should get you to the right location.
