Crystal Lake Camps is primarily a resident summer camp for boys and girls ages 7-17 who attend a Christian Science Sunday School. We provide internships and job opportunities for people 18 and older. From late August through May, Crystal Lake welcomes families, school classes, businesses, and other groups for seminars, retreats, rest and study as well as other events.
