Johnsonburg camp and retreat center is a 300 acre summer camp and guest facility that serves thousands of campers and guests every year. We are located in the scenic New Jersey highlands, conveniently only ten minutes from the I-80 exit for Hackettstown and within a short drive to Blairstown. From large school groups to intimate church retreats to woodsy weddings to our beloved summer camp program, Johnsonburg is memorable, restful, and a lot of fun.
