About this park

Sullivan Lake covers 1291 acres and has a depth of 320 feet. Hall Mountain rises abruptly from the eastern shore of the lake to a height of over 6000 feet. The densely wooded nature of the campground provides privacy at each campsite, and plenty of shade for warm summer days. Wildlife such as elk, moose, white-tailed deer, and black bears can be spotted in the area. In the fall, the surrounding forests are ablaze with the yellow foliage of western larch and aspen.
