Maine Wilderness campground
Stayed here 2 nights in June. Wooded sites on the shore of the largest lake in New England. Our site was large enough for tents and hammocks; which was nice to have options. The sites are also far enough away from each other that you dont feel like you're in an apartment building. Central bath and free shower house with laundry/dish sinks outside was an added bonus. Fire ring and table at each site. Rangers were super nice and helpful. Trails to beach area with a playground for the kiddos. Its pretty remote so make sure you have everything you need before venturing past Greenville. Take the drive up to(and past if you're real adventurous) Kokadjo for moose spotting.
