The Outdoor Education campus at Finniss is used by students from years 4 to 10 for annual camps, with camps culminating in Year 10 with the 21-day Peak Experience in the Flinders Ranges. In addition, students have the opportunity to join the Exploration Society, which allows boys with a passion for outdoor activities to pursue more challenging ventures. Activities include hiking, kayaking, rock-climbing, mountain bike touring and cross country skiing. St Peter's College's exchange program has links with schools in Germany, France, China, South Africa, England, Switzerland, Mexico and Canada.
