For a map or complete description to all the trails order Porcupine Mountains Wilderness State Park: A Backcountry Guide for Hikers, Backpackers, Campers & Winter Visitors by Jim DuFresne from the eshop:

The highest point of the trail - 861 feet - is at the trailhead. From there you quickly enter an old growth forest, a stand of impressive hemlocks and later northern hardwoods such as maple and yellow birch and begin a mild descent. At Mile 1 the trail arrives at the Pinkerton Creek bridge where on the other side you climb the bank to a bench. The trail levels out briefly, then descends to cross a feeder creek on a slab bridge.

The trail levels out again, angling towards Little Carp River through the impressive forest and at one point passes a lighting-struck tree posted with “1988”, the year of the storm. At Mile 2.2 you emerge on the edge of the Little Carp River Gorge to see the rushing stream below. From here it is a gradual half mile descent to the Lake Superior Trail junction.

To the west Presque Isle River is a 6.3-mile trek while Little Carp River Cabin is just up the trail to the east. The mouth of the Big Carp River is still 1.3 miles to the east but reached along a very scenic stretch of the Lake Superior Trail that hugs the shoreline.
