A favorite event of the Can-Am Festival, Huntington Beach State Park hosts the 18th installment of this interesting and educational day. Visitors will encounter live animals, view local seashells and fossils, and learn about the history of the Lowcountry. The beach and Atalaya, the castle-like home of the Huntington family, are also great sights to take in while visiting the park. Free with park admission. (843) 237-4440, www.huntingtonbeachsc.org
