The University of Idaho's McCall Outdoor Science School (MOSS) provides an excellent setting for TTCC. Located about an hour north of Boise, the 14-acre McCall campus offers a rustic retreat setting with 600 feet of lakefront beach, home-cooked, nutritious meals and bunkhouses and cabins. Ponderosa State Park surrounds the campus and offers hiking, Nordic skiing, mountain biking, boat ramps, trailer hook-ups, and a wide variety of evening interpretive programs.
