Aldabra Main Channel is a drift dive through a remote atoll passage, where strong tidal currents carry divers along the reef. The site features depths between 15 and 25 metres, with an average of 18 metres. Visibility ranges from 10 to 30 metres. Divers must use boat access and guided tours to navigate the exposed conditions. The current is the defining feature, requiring careful timing with tidal flows. A wreck located at the site presents an entanglement risk, so divers should maintain buoyancy and avoid penetration. The reef environment supports a variety of marine life typical of the region, including reef fish and invertebrates.

Assumption Island in the Seychelles offers accessible snorkeling along its northwest coast. The site features a mix of reef and seagrass habitats located approximately 200 metres from the shore.

Assomption transit is a reef and wall site located off Assumption Island, Seychelles. The topography features a drop-off that descends to 40 metres, making this an intermediate-level dive suited for those with solid buoyancy control. Divers can expect consistent visibility of 30 metres and moderate currents. Access is by boat only. Due to the presence of sharp coral and rocky surfaces, careful finning is required to avoid contact with the substrate. Divers should remain aware of potential hazards, including boat traffic, and are advised to deploy a surface marker buoy before ascending. Water temperatures at this site range from 25 to 28 degrees Celsius throughout the year.
