Delaware County, offering an eclectic mix of communities, borders the western edge of Philadelphia and extends southwest to the Delaware line, west to Chester County, and north to Montgomery County. The county contains many historically significant sites and properties, including handsome homes, some of which were originally the summer homes of wealthy city residents (and many of which have been converted into lovely apartments). Outlying communities range from semi-urban to semi-rural and contain a mix of housing options to suit every taste and budget as well as a large variety of cultural, shopping, dining and entertainment venues. A large portion of the county contains an extensive network of rail/bus service, and Philadephia International Airport and arteries such as I-95, Route 3, and the Blue Route (476) provide easy access to the Philadelphia region and beyond.
