Delaware Water Gap Mining Circuit

The bluestone that built New York City’s sidewalks came from these mountains, hauled down narrow quarry roads that cling to cliffsides above the Delaware Water Gap. The circuit connects three major quarry sites via original haul roads, including the infamous Devil’s Backbone section where loaded wagons once navigated a knife-edge ridge with thousand-foot drops on both sides. Modern drivers face the same white-knuckle exposure, plus loose shale that makes traction sketchy in wet conditions.

This is difficult territory demanding experienced drivers and proper equipment. Rocky ledges and off-camber sections require careful throttle control and good spotting. Skid plates and recovery gear are mandatory – the dropoffs are unforgiving. Best tackled in dry conditions from late spring through fall. No permits required but check for hunting seasons. The reward is spectacular views of the Delaware Water Gap and a genuine appreciation for the quarrymen who did this route daily with horse-drawn wagons loaded with stone.
