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.

Passe Dubois is a reef site located within the Aldabra atoll in the Seychelles. This drift dive site is accessed by boat and is situated 700 metres from the shore. Divers and snorkellers can expect a shallow experience with depths ranging from 3 to 10 metres, averaging 8 metres. The site features mild currents and visibility that fluctuates between 10 and 50 metres. Due to the nature of the pass, potential hazards include entanglement, sharks, and strong currents. The site is suitable for beginners and offers a typical dive duration of 45 minutes. Water temperatures remain warm throughout the year, ranging from 25 to 30 degrees Celsius.

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.
