The Incendio Challenge was an obstacle course housed in a greenhouse located on the grounds of Hogwarts Castle, near a Herbology classroom. As the name suggests, the course was meant for practising the Fire-Making Spell, Incendio. The course contained a large number of objects that could be moved around, knocked over, or otherwise interacted with using Incendio. The room also contained a number of Challenge Stars. The Challenge was also infested with gnomes and Doxys.
During the 1991-1992 school year, Pomona Sprout tasked Harry Potter, and presumably other students, to collect all of the Challenge Stars within the Incendio Challenge, a task Harry completed successfully.
