There is no state park named “Capital City State Park” in New Jersey. Capital Park, a planned green space between the State House and the Delaware River in Trenton, had not opened as of 2026. The state park that runs through Trenton is the Delaware and Raritan Canal State Park.
America's State Parks is an independent online guide to state parks and other public lands in the United States. Our editorial team compiles park profiles from official agency and operator sources and other identified references, and follows our published editorial policy and review methodology. Where a profile shows a source-check date, that date applies to the detail it names. We correct errors when we find them or when readers report them.
