The car barge on STT is the first entrance coming from Sapphire at the Red Hook ferry dock.
the 2nd entrance is for the passenger ferries.
The car barge is on the south side behind the tennis courts on STJ.
The passenger ferry comes in to downtown Cruz Bay.

You can get your tickets on the car barge. One way or RT but RT is cheaper however you can only come and go with that ticket on the ferry company that you purchase the ticket for as companies do not work co-operatively and interchange tickets.
The barge schedule is usually on the back of the ticket and you should ask the person you get ticket from if there are any planned changes in the schedule. Best not to take the last ferry and always be there at least 15 -20 min. prior to departure.

Backing on is no problem as long as your car isn't 2 inches off the ground.
You can also ask the attendant to back it on for you if it scares you silly but not difficult at all unless your car is too low to the ground.
Hope this answers your questions.

Yes it does! Thank you very much!

Greetings. I have found that Love City Car Ferries (CAPT VIC) and Global Marine (ROANOKE) accept each others tickets.

for some reason I thought they were the same company? They don't allow you to interchange between Boyson and the others however so best to check when you get on the barge to STJ which barge(s) you can come back on and the times of departure.
I like Capt. Vic and Roanoke much better for travel back and forth so always try to schedule my comings and goings with them.

Sometimes there are service interruptions for various and sundry reasons so if not all the barges are running, you will experience delays and even changes in schedule.

Enjoy St. John! There's lot's to do, see and explore! Plus, it's way cheaper to take your vehicle over on the barge and come and go as you please, when and where you please, than be at the mercy of the taxi's.

Hi beer..
Thank you very much for your Valuable Information..

It was all much easier than what I thought. Very simple and a smooth ride the day we went, but if you want to get out and ride from the top make sure you get out before anyone parks next to you! I got stuck in the car on the way back, but with the windows down it was still a nice ride inside the car.

About the only hang up I could see is the round a bout on St John. We were going to the north shore beaches and guessed correct, I think it was the second left once in the round a bout that ended up taking us to route 20.

Either way it was much easier than expected and nothing to worry about 🙂

Wow, it would't have occurred to me that you could get parked in. That's good to know, thank you.

Sorry to bring up an old thread, but I just wanted to make sure the car barge schedules haven't changed since the last time we were down to STT. I checked the link for the ferry schedules, and it looks like they still run every 30 minutes (different companies/barges, it seems), so something tells me we don't need to worry about catching any one in particular. We're renting a minivan, and I imagine it will not be an issue for any of the barges, correct?

Thanks!

Correct as long as company you're renting from allows you to go to STJ with their car.
Get there in plenty of time to make the barge of choice on both legs of trip and ask if there any changes in schedule when you pay for ticket on the barge. The times are usually printed on the back but as previously stated there can be variations. RT is most cost effect but be aware that some tickets are not interchangable on specific barges. Can't use a Roanoak/ Capt. Vic ticket to come back on a Boyson barge for example.
