Travel by boat between Mahé, Praslin, and La Digue is easy and relatively cheap. The Cat Coco ferry connects Mahé and Praslin, and takes about the same time as the flight (factoring in the need to arrive 45 minutes before a flight). About 50 minutes one-way, the ferry runs three times a day (only twice on Sundays), for US$55 one-way ($70 in the upper air-conditioned lounge). Children under 12 pay half. Book through the ferry or a travel agent at least a day in advance during high season. Free shuttles to and from the airport are sometimes available.
To get to La Digue, Cat Coco runs one ferry a day from Mahé (via Praslin) and twice on Sundays (about 90 minutes, US$70 one-way). You can also take the Inter-Island Ferry (30 minutes) to La Digue from Praslin, which runs about seven departures daily in each direction from about 7 am to 5 pm (US$16 one-way). The ride can be a bit bumpy during the southeast monsoon. Book ahead through your hotel or tour operator.
