Warren County sits in the far northwest corner of Jersey where the Delaware River and the Kittatinny Mountains do most of the talking. The Delaware Water Gap National Recreation Area runs along the western edge – hiking, kayaking, waterfalls, and some of the most dramatic scenery in the state. Hackettstown is the county’s main hub and home to the M&M’s factory, which is exactly as fun as it sounds. And Blairstown – a tiny town with a great main street – is where Friday the 13th was filmed, which is either a selling point or a warning depending on who you ask.
