We found a great spot right next to the river on forest road 330C near North Fork Campground. The area was fairly busy on Labor Day weekend but we were basically isolated in this spot. One family was camping a little further up the road, but we had zero traffic on our road and the spot was beautiful. We were nestled up against the Little Laramie River which was awesome. We did explore the area a little and found numerous dispersed camping spots in/around the area but none as nice as the spot that we settled on. The exact coordinates are:
