Sister Bank is a drift reef site located between Praslin and La Digue in the Seychelles. The reef topography ranges from 18 to 30 metres in depth, requiring divers to be comfortable with buoyancy control and depth management. Access is strictly by boat, and the site is suited for intermediate divers due to the potential for changing currents and the presence of a cave or swim-through. Visibility typically spans 15 to 30 metres. Divers should note the overhead environment hazard and avoid entering confined spaces without appropriate training and equipment. Guided tours are recommended to assist with navigation and managing the drift conditions.
