Sunnydale is a fictional town in California, known primarily as the setting for the television series Buffy the Vampire Slayer. The town is characterized by its sunny weather and a high school, Sunnydale High, which serves as a central location for many of the show's events. The town is also infamous for its connection to supernatural occurrences, including vampires, demons, and other mystical beings. This is largely due to its location on a mystical portal known as the Hellmouth, which attracts various dark forces and challenges for the show's characters, particularly Buffy Summers.
