The Journey
An alternative to another domestic flight, if the Mekong is already on your route.
Most people fly to Phu Quoc, and for most itineraries that is the sensible thing to do. But if you are already working your way through the Mekong Delta, crossing by sea from Rach Gia saves you doubling back to an airport and makes the island feel like the end of a journey rather than another departure lounge.
There are two ways to do it. A high-speed passenger boat takes around two and a half hours and suits travellers without a vehicle. A vehicle ferry takes roughly three to three and a half hours, carries cars and motorcycles, and is the larger, steadier option. Worth saying plainly: neither is a scenic cruise, and the speedboat is a scheduled passenger vessel rather than a private boat. It is transport, and it is a good deal more interesting than another flight.
