Camp Whitcomb/Mason is a year-round facility located near Hartland, Wisconsin, approximately 35 miles (56 km) northwest of Milwaukee, Wisconsin on Lake Keesus. Founded in 1911 and owned and operated by the Boys & Girls Clubs of Greater Milwaukee, it is the oldest Boys and Girls Clubs camp in America.
Set on 306 acres (1.2 km²) of hills, fields, wetlands, and forests, Whitcomb/Mason provides campers with a variety of natural experiences. Their lodges, cabins and pavilions are available for rent to school, family, church, non-profit and corporate groups throughout the year. Accredited by the American Camp Association, the camp operates residential (overnight) and day camp programs throughout the summer.
The mission of Camp Whitcomb/Mason is to provide an imaginative, outdoor educational/recreational experience where youth have the opportunity to develop a sense of competence, usefulness and belonging through their accomplishments, while developing skills, responsibility and respect for others in a safe and healthy non-urban environment. Students are encouraged to have fun while being courteous of the property, wildlife and volunteers.
