Although COA is a small college, it offers quite a bit for students to do.  The Student Activities Committee plans most events such as trips, concerts, and helps with funding for workshops.

The College fields intercollegiate club teams in men's and women's soccer. Club squads compete in volleyball, basketball and indoor soccer.  All are open to members of the COA community. Also, the College's location enables students to participate easily in outdoor activities.

The College's recreational fleet includes river and ocean kayaks, white water and lake canoes, and Rhodes 19 and Sonic 23 sailboats. The College's newest 38' research boat, Indigo, will be used for a variety of field trips and research projects along with other smaller craft. A sailing class is available to those interested each fall term. A nominal fee is charged.

Another popular activity is SCUBA diving. COA divers either come to COA with basic training in diving or may take a YMCA-sponsored course.

Students also organize activities on their own, such as playing soccer, frisbee and volleyball on the front lawn, holding informal drum circles in front of Turrets, and putting together a weekly Open Mike night.  There are also many activities sponsored by Student Organizations.
