Logmark is a canoe-in campground located on the Pere Marquette River between Lower Branch Bridge and Maple Leaf Access, accessible via a 1. 25-hour paddle from Lower Branch Bridge.

This primitive camping area offers a legal overnight stop for paddlers on the designated Wild and Scenic River, though it has minimal facilities and barely a flat tent spot.

The site is marked by a small wooden sign visible from the water on the north bank in a stretch of white cedar.
