Catch peak fall colors by setting sail on one of Classic Harbor Line Boston’s Fall Foliage Cruises (boston-sailing.com). The two-hour lunch cruises feature a gourmet picnic lunch and hot cider, while the two-and-a-half-hour weekend-only brunch version boasts a three-course meal and optional cocktails. On both excursions, which depart from Rowes Wharf, you can let your eyes drink in the city skyline as well as the vibrant autumn colors of the Boston Harbor Islands, all while hearing equally colorful narrations on board the 1920s-style yacht Northern Lights that put a unique spin on seasonal leaf peeping.
