The trek from Hatchet Lake to South Lake DeSor via the Greenstone Ridge Trail is a 8.1-mile day that in the first half offer a bit of climbing and some fine views of of Siskiwit Lake, Malone Bay, even deep into Siskiwit Bay. At the halfway point you reach Ishpeming Point (1377 feet), the second highest point on Isle Royale.

The climb is an easy one to the point marked by a lookout tower, the lowest one on the Island by far. Now used for research by the park staff, the tower was built when Ishpeming Point was bald but now the surrounding trees are taller than the structure so there is no view whatsoever. The Point is also the junction to Malone Bay with Ishpeming Trail departing south and reaching the campground in 7 miles.

The next segment to Lake Desor is completely different from the trek from Hatchet Lake. The 3.8-mile walk to Lake Desor is shorter and has less up-and-down hiking but provides few views except for the trees next to the path.
