Provided with one of nature's most beautiful natural aquatic areas, Stewart utilizes the Red Cross swimming program. S wimmers are grouped according to their abilities at the beginning of each term and progress from that point. Water-skiing is done on the Guadalupe between Stewart's senior pool and Senior bridge.
Campers enjoy the water weeny, bumper tube, skiing and slalomming.
Sailing , a selective activity, is also done on the Guadalupe River, in one of the camp's sailboats.
