We visited with our dog the first week of October to catch the fall colors. After driving up from Chicago, checking in, and then driving to Little Carp River Road, finally ready to hike at 4pm. Parking lot isn't huge and all sites were booked that weekend but we were able to snag a spot. We took the Little Carp River trail all the way to the site, which was easy to follow, a good bit of up and down but nothing too difficult. Reservation site says 2.3 miles, we did closer to 3.5 by the time we arrived. LC-7 and LC-6 are close to each other but far enough away that you have some privacy, couldn't hear the other party chatting. Fire wood in the area was sparse, everything was damp. Bear pole was tough to find, follow the trail past the site, then a stump, at the second huge tree on your left, turn to your right and climb the hill.
Site has a fire pit, logs to sit on and plenty of level space to pitch tents. It is right on the trail, so you may see some traffic. Good coverage from old growth trees, enough hills in the area to find privacy for squatting, and the river is easy to access. If I had to choose between LC-6 and LC-7, would pick 6, it's up higher and further from the trail.
We hiked back the next morning, went to Lake in the Clouds and then Ontonagon for lunch. Visited Squeeze on Main for food and beer, place is brand new, looks nice, price reasonable, food was ok. Then the bar a few doors down for more beer, they had a good selection.
Then we drove to the Pinkerton Trail head, limited parking on the side of the road, but room enough on the end for a few cars when we arrived. Pinkerton was a pleasant stroll through the woods, lots of boards, dead falls, and mud, and it's a gradual descent. Met up with the Superior Trail 3 miles in, then went left to LS-3.
LS-3 is everything we came for - right on the lake, plenty of firewood, ultimate in privacy since no other sites are within at least a half mile, perfectly level spot for the tent and a built-out fire pit area. Highly recommend.
