International Sports Training Camp (ISTC) is a fun-fueled summer sports camp for kids ages 8 to 17. Our private 500-acre facility is located in the beautiful Pocono Mountains of northeast Pennsylvania. From the fall through the spring, ISTC becomes Trout Lake Retreats and Conference Center. At Trout Lake, we host a variety of groups ranging from churches to schools, YMCA’s to weddings, corporations to scouts, sports teams to interest clubs, and everything in between.
