Cruises from St Joseph
St Joseph Atoll is part of the Amirante Islands group, in the Outer Islands coral archipelago of the Seychelles islands, in the Indian Ocean. St Joseph Island lies 250 km WSW of the capital Victoria on Mahé Island. The main Saint Joseph island is a crescent shaped, flat coral sand cay, 2.2 kilometres long and averages 400 m wide. The maximum width of the fringing reefs of the atoll is 6.6 km.
The inner lagoon (depth to 6.4 m) drains on the western side over a sill, leaving the reef entirely exposed. The atoll has 13 sandy islets covered by coconut trees, and shifting sand bars surround the lagoon.
