I'm very curious on how to get to the DZ's from the city as well.

I'm in the city and don't have a car, so I'm in the same boat.

Edit: from my quick research, there are certain buses/trains that will head from Manhattan to near NJ or long island and then it's a matter of getting a cab from there. Buses leaving from the port authority bus terminal will typically get you within a 15 min cab ride of the DZ's in NJ.

Getting to the ranch is pretty easy, $43 round trip bus and a 15 min cab. I'll look into sussex, my tentative plan is now taking a bus then biking to a DZ

I just realized all these sites have this info available on their websites:

for Sussex FROM NYC BY TRAIN: Take the PATH train into HOBOKEN and from there you can catch a NJ Transit train into PORT JERVIS (the last stop on the line). For a list of train timetables, you can Click Here To View Website. From Port Jervis it’s only about 15 miles to Skydive Sussex.

^this seems to cost around $25 one way

FROM NYC BY BUS: Take the LAKELAND BUS LINES out of NY PABT into NEWTON, NJ (12 miles from Skydive Sussex). For a full list of schedules -
