The Philadelphia Zoo is open rain or shine. You may reschedule your visit up until 11:59PM the night before your scheduled visit. Once that time has passed, your tickets are confirmed and your reservation will not be able to be edited. Our terms state that tickets to Philadelphia Zoo are non-refundable, rain or shine, and we, unfortunately, we do not have the ability to offer rain-checks.
