There are a couple of developed campgrounds at the top, with tables and toilets, and 9 primitive “yellow post’ campsites. Yellow post means that you can have campfires as long as the fire stays within the designated fire ring and as long as fire restrictions allow. Thomas Mountain Campground is on the summit. and is a very popular spot for locals to camp due to the amazing views and solitude.
