A Florida Keys vacation to Marathon with Bluegreen Resorts can be as active or relaxing as you'd like. Go scuba diving with a loved one, or go kayaking and swimming in the clear blue seas. Charter a boat and go deep-sea fishing or enjoy the peace and quiet of the famous flats of the Keys. Explore nature's surroundings during a private kayak tour or a seaside bike ride. Then ride off into the sunset on your Jet Ski rental.
