There is only one way to get to these islands and that is by boat. Some of these islands are located in areas that are so remote that traveling to them by boat will take some time. However, there are plenty of boats that travel to the islands from Réunion, which is an island off Madagascar. The best way to get here is to take any of the ships that leave from Réunion and that are headed to the particular island that you are interested in. However, be aware that this might take some time, especially if you are visiting the further islands because the ship will need to stop in many different locations to deliver goods. Also, the ships travel to the islands on a regular schedule so you should ask around and figure out when the next one leaves so that you can book your seats. Make sure that when you are travelling to these islands that you bring everything you need so that you do not feel stranded in case you do not find something you need to purchase on the islands.
