Connects Threemile camp with Greenstone Ridge Trail. Greenstone is 1.5 miles from Tobin Harbor Trail. Tobin Harbor is .5 miles from Threemile.
2 mile trail back to the south side of the island from Greenstone ridge. Tough hiking on the northern half as you're traveling down hill for a while. I took this trial on my last day in Isle Royale and was moving quickly as I was ready to try and catch a ferry to leave. I recall this trail about midway became hard to identify. We ended up hiking 100 meters or so in the wrong direction at one point. I don't recall any water sources on the northern half of the trail but there is some on the southern half.
