The campsite was easy to find, and has a single parking area with one spot for each of the four campgrounds. There's also an informational board at the parking area, so we never needed to ask the host for anything. The Cadillac Mountain campground, where we stayed, was the furthest in walking distance from the parking area. This made it feel more private, but if you have any heavy gear it'll be a workout to carry it to camp!
We easily found a relatively flat and comfortable place to set up our tent. There is a fire pit and a picnic table at each campsite, but if you're planning on cooking over the fire, as we did, please note that there is no metal grate to put over the fire, so bring your own if you need it! If you have, and have the space for, folding seats or stools, those would have been nice to set up around the fire as well. The host provided a full 5 gallon bucket of water for you to extinguish the fire, though, which was a thoughtful touch.
