The waterfront has lots of fun things to do. Restaurants are plentiful, endless shopping, or just sit along the harbor and watch the boats. There's plenty for all ages. Many locals and tourists hang out there. Don't miss the huge Boston Aquarium! We spent 4 hours in there and loved every minute. It was a highlight of our trip. Adults and kids love this place! Just across the main street is Quincy Market. Tons of shopping and eateries. Outdoor seating, and musical entertainment abound. A truly fun experience. We went there nearly every night. Loved it!
