Is it all possible to plan a road trip in the Caribbean? Trinidad & Tobago seems to have a ferry, but that is within one country.
I am looking for a ferry enabling me to do a road trip through islands of multiple countries.
There are some but they all cover short distances, often only within 1 country as you have seen.
The ones I've found...
If you plot those on a map you'll see the coverage leaves a lot to be desired. There are probably other services but I doubt you could string together enough for an island-hopping "road trip".
Surely a sailing tour would be better anyway?
