I think the campfire begins at 7pm (probably later during Daylight Savings Time). You can purchase or bring your own marshmellows/sticks for toasting. There is a barrier to prevent anyone from getting too close. A movie follows the campfire.
Anyone with young children should be very careful during this event. Lots of people and children gathered/running around a fire carrying pointy sticks with hot goo! Make sure your kids are supervised and assisted.
You can also purchase or bring snack to eat during the movie. Lots of fun. Good way to wind down from a long day.
