Blue Ridge Summit is a census-designated place in Franklin County, Pennsylvania, United States, southwest of Gettysburg in the central part of the state, adjoining Pennsylvania's southern border with Maryland. It is less than 3 miles east of Pen Mar, Maryland.
The community is known for being the birthplace of Wallis Simpson, the late wife of Prince Edward, Duke of Windsor (previously Edward VIII of the United Kingdom). It is also home to one of the 15 oldest golf courses in the United States. Built before 1885, the Monterey Country Club has served as a summer retreat for many Washingtonians, and American Presidents Woodrow Wilson, Calvin Coolidge and Dwight D. Eisenhower have all played the Monterey Country Club course.
