OAC is a co-ed camping experience for 5th-11th graders. Campers spend the first half of the week exploring outdoors and tent camping at Hartman Creek State Park and the second half experiencing the traditions at Camp Onaway. They’ll also experience canoeing, kayaking, trail hiking, and biking, and older campers have rock climbing, backpacking, and whitewater kayaking opportunities. Led by experienced leaders, OAC allows youth to try new hobbies with gear provided by the Brigade.

Anchor Camps are for youth who have just completed 5th grade to introduce them to the magic of Onaway Island. They'll experience many of the activities that take place at a week-long camp, including reveille, flag raising, morning dip, free time activities (including swimming, tubing, kayaking, crafts, topside games, cross-country race), chapel, campfire, and taps to end the day.

Experienced 8th-11th grade campers act as cabin leaders to help familiarize the 5th graders with life at camp.
