christopher reeve and jane seymour can be seen sitting near the lighthouse in the 1980 movie "somewhere in time" which was filmed primarily on mackinac island. the lighthouse is off-limits to anyone who may visit the island. while it is rare for round island to see any visitors, there is a small harbor on the north shore that attracts occasional inhabitants of mackinac island who sail to the harbor's sandy beach for a secluded, quiet visit. (the beaches of mackinac island are generally rocky.)
