Mercer County, New Jersey
Mercer County sits in the center of New Jersey, straddling the line between north and south. It’s home to Princeton University so it gives the area a serious intellectual vibe. Trenton is the state capital, which adds political flavor to the mix.
History runs deep here. Washington crossed the Delaware River in these parts, changing the course of the Revolutionary War. The county has a bit of everything. You’ll find busy suburbs, quiet farmland, and urban areas. Mercer has restaurants ranging from high-end to hole-in-the-wall gems.
Nature lovers can explore the Delaware and Raritan Canal State Park. It’s a great place for a bike ride or a lazy canoe trip. Art is a big deal too, with sculptures at Grounds for Sculpture. Mercer County is a place where past and present, city and country, all come together.
