There is a lot to do in Bucks County.
Most people mix it up.
Possibly a little biking , maybe a hunt through some of the antique shops scattered throughout the area, or a visit to the Sand Castle Winery for the afternoon. Glider rides and light aircraft sight seeing are available at Van Sant Airport. For history, well, Washington did cross the Delaware 20 miles down river. And for kids, Seasame Place and the Crayola Crayon Factory are nearby. This map is a good reference.
