Driving your vehicle on the beach

You can drive a 4 wheel drive vehicle on the beach, with a valid permit, to gain access to areas of the park where you are allowed to surf fish. The Island Beach State Park issued permits though do not allow anyone to just drive around on the beach.
A three day permit is $50.00. It is valid for 72 hours, starting from midnight of the day of purchase. The number of three day permits that are issued is limited during the summer season. Annual permits are $195.00 and are valid for one calendar year. They are valid from January 1 and run through December 31 regardless of the date of purchase. You can obtain additional information about beach driving permits by calling the park at (732)793-0506.
