• BE ADVISED: Swimming in the Delaware and Raritan Canal is a prohibited activity. As per NJ State Park Service Rules and Regulations swimming may take place ONLY IN A DESIGNATED SWIM AREA. In recent years, illegal swimming activity has increased in the Prallsville Mills area of Stockton in both the Canal and historic lock. This area is fenced and posted. This is considered a RECKLESS ACTIVITY and in violation of the New Jersey Administrative Code. Increased park police patrols have been instituted and VIOLATORS WILL BE SUMMONED.

  • BE ADVISED: The State Forest and State Park Services have identified the D&R Canal State Park as a high-use area for the preemptive felling of ash trees to reduce the anticipated hazards caused by the Emerald Ash Borer infestation effecting the State. At-risk, dying and dead ash trees will be harvested along the path. These areas will be replanted with new seedlings. It is estimated that approximately 1,550 trees, 5-inches or more in diameter, leaning over or located with 15 feet of the path will be felled. Click here for more information on the Emerald Ash Borer and the progress of the project here at D&R Canal State Park. Thank you for your patience.

  • BE ADVISED: Due to the continuing NJDOT Route 518 Canal Bridge Replacement project the SMALL D&R CANAL STATE PARK PARKING LOT located in Rocky Hill near the light with Canal Road WILL REMAIN CLOSED. Visitors are asked to park in the Kingston or Griggstown lots. Use of this lot is expected to resume in late Spring 2017. The towpath will not be effected and will remain open. Thank you for your patience.

  • BE ADVISED: A dredging project is planned for the D & R Canal from Kingston to Amwell Road at East Millstone. This extensive project (administered by NJ Water Supply Authority), slated to begin in 2016 but now pushed up, may take up to two years to complete. Click here for details about this project.

  • PLEASE NOTE: Park users, campers, hunters and all visitors to the D&R Canal State Park are asked to call 1-877-WARNDEP if they require the assistance of our State Park Police. Please do not hesitate to call AT ANY TIME if assistance is needed. In the event of a life threatening emergency we ask that you please call 911. And as always, we ask that the public contact our office to report any fallen trees or other obstructions encountered along the length of the path. ENJOY THE PARK AND BE SAFE!
