The Pumpkin Festival is an annual event, held at Cal Poly Pomona or California State Polytechnic University in the Los Angeles metropolitan area. Pumpkin Festival takes place for two days in October, while the Pumpkin Patch continues to be open through the end of the month. In addition to a large patch, the festival features a traditional corn maze, horse rides, a petting farm, live music, games, and contests run by student clubs.
The festival was started in 1993, drawing thousands of visitors to AGRIscapes at the Don B. Huntley College of Agriculture at Cal Poly Pomona. Over 40,000 pumpkins are grown for the festival each year. "Ag Discovery Lane" features free exhibits and demonstrations for visitors, such as cow milking demonstrations and the famous Insect Fair with over 500,000 insects from around the world.
