Just like its name, the Forbidden Forest is strictly off limits to students. Well, students who listen to the rules anyway. The forest is dark and dreary, the tops of the trees so dense that no light can get through. Among the creatures inside the forest, there are centaurs, unicorns, trolls and thestrals. There are also a lot of spiders in there, wanting to avenge the death of their leader, Aragog. They're big spiders too!
