Yes, sometimes. But the ferry ride is the easy part. The real question is whether your ship gives you enough time to cross St. Thomas twice and still enjoy St. John without watching the clock.
Someone will tell you to go to St.John.
They are not wrong.
The question is whether your cruise day is long enough to make it a good idea.
St.John is close to St.Thomas.
But your ship is not docked beside the St.John ferry.
That missing piece is where overly optimistic itineraries begin.
The Short Answer
If your ship gives you a long port day , St.John can be one of the best things you do.
If your ship gives you a short stop, stay on St.Thomas.
Do not spend a four - hour port call proving that two islands technically fit into four hours.
The Actual Journey
For most cruise visitors, the day looks something like this:
Cruise port → taxi across St.Thomas → Red Hook → passenger ferry → Cruz Bay → taxi / Jeep on St.John
Then you reverse the entire process.
The ferry crossing itself is relatively short.
The full journey is not.
Current Red Hook Ferry Service
Passenger ferries operate daily between Red Hook, St.Thomas and Cruz Bay, St.John.
The Virgin Islands Port Authority currently advises passengers to arrive at least 15 minutes before departure.
Schedules can change seasonally.
Check the current timetable for the exact date of your cruise rather than building the trip around a screenshot from six months ago.
How Much Time Should You Protect for the Return ?
More than you think you need.
Your ship's all-aboard time is the important number, not the departure time printed at the top of the itinerary.
Work backward from all - aboard.
Then protect time for:
• ferry check -in
• ferry crossing
• taxi from Red Hook
• St.Thomas traffic
• getting through the port
• a missed / full / delayed connection
I would rather be drinking something near the ship 45 minutes early than watching the harbor from a taxi while doing increasingly creative math.
When St.John Makes Sense
A St.John cruise day works best when:
• the ship arrives early
• you have roughly seven or more usable hours in port
• weather is good
• the ferry schedule gives you multiple return options
• everyone in the group understands this is the main activity
Do not combine St.John with six other St.Thomas stops.
St.John is the excursion.
What Can You Actually Do in Three to Four Hours on St.John ?
More than you might think if you keep it focused.
Option 1: North Shore Beach
Arrive in Cruz Bay.
Take a taxi to one North Shore beach.
Stay there.
Return.
That is probably the cleanest first - time plan.
Trunk Bay is the obvious choice if you want the famous one.
Hawksnest or another North Shore option may work better depending on conditions and crowds.
Option 2: Cruz Bay + Beach
Spend a little time around Cruz Bay, then taxi to a nearby beach.
This gives you some sense of the island without turning the day into a road tour.
Option 3: Private Driver / Island Tour
If you want to see several overlooks and beaches rather than spend hours swimming, arrange transportation and let someone else manage the route.
For a short visit, efficiency matters.
Should You Rent a Jeep?
Usually not for a standard cruise day.
You would need to:
find the rental office
complete paperwork
orient yourself
drive unfamiliar steep roads on the left
park
return the vehicle
Taxis are simpler when you only have a few hours.
Save the Jeep for the trip when you come back and stay.
Should You Take the Car Ferry ?
Not for a normal cruise day.
The passenger ferry is much simpler.
Car barges load first - come, first - load, and VIPA explicitly notes that an online ticket does not guarantee a place on a particular barge.
That is not the kind of variable I would voluntarily add to a cruise schedule.
What If the Ship Docks at Crown Bay ?
You are farther west.
That means more time crossing St.Thomas to Red Hook.
The trip can still work on a long port day, but the transportation margin becomes even more important.
What If the Ship Docks at Havensight ?
You are somewhat better positioned for the drive east toward Red Hook, but you still need to account for traffic and taxi loading.
Do not confuse "closer" with "next door."
What About the Charlotte Amalie Ferry ?
Passenger service between Charlotte Amalie and Cruz Bay can sometimes create another option, but sailings are more limited and schedules are seasonal.
If the times happen to align beautifully with your ship, it can be useful.
If they do not, Red Hook remains the more frequent connection.
Always check the current schedule.
When I Would Not Go
Stay on St.Thomas if:
• you have a short port call
• all - aboard is early
• weather is questionable
• ferry service is disrupted
• your group moves slowly
• someone is anxious about missing the ship
• you want to see several St.Thomas attractions too
There is no prize for making the itinerary harder.
St.Thomas has excellent beaches.
When I Would Go
Go to St.John if:
• you have a genuinely long day
• National Park beaches are the reason you're excited
• everyone agrees this is the day's main event
• you are willing to leave St.John earlier than feels necessary
That last one is the key.
The Better Question
Do not ask:
"Can I get to St. John during my cruise stop?"
You probably can.
Ask:
"Will I have enough time on St. John for the crossing to be worth it?"
That is the decision.
Local Tip
If the schedule feels tight while you're planning it from your couch, it will feel much tighter when you're standing in Cruz Bay looking at the water and realizing you have to leave.
Give St.John a proper day.
And if this cruise stop doesn't give you one, that is a very good reason to come back.
