Triangle Oktoberfest at Koka Booth Amphiteatre is a large-scale, authentic German heritage festival held in Cary. What to Know: Admission to this community event is free, though you will want to budget for traditional food and drinks. The venue is highly stroller-friendly with paved pathways, making it easy to navigate with younger children. Parking is available on-site, but the main lot fills quickly, so arriving close to the 5:00 pm start time is highly recommended if you are bringing kids. This is an excellent weekend pick because it offers a lively, festive atmosphere where parents can enjoy authentic food and music while children enjoy the open grassy areas of the amphitheater.
