Rasgefanno

Rasgefanno

Rasgefanno is a deep outer reef site in Addu Atoll (Seenu Atoll), located in the far south of the Maldives close to the equator. The site offers a steep reef wall that plunges to well beyond recreational depths, with a pronounced overhang structure and rich pelagic activity driven by Indian Ocean upwellings.

Site Conditions

• Depth range: 15–40 m
• Typical visibility: 20–40 m
• Currents: Strong; oceanic surge common on the outer wall
• Best season: December–April (northeast monsoon) for clearest water

What to Expect

The upper reef plateau at 15–20 metres features hard coral gardens and scattered bommies teeming with butterflyfish, angelfish, and abundant reef chromis. Below 25 metres the wall becomes vertical, studded with large sea fans and black coral bushes. Addu Atoll’s isolation gives it a distinct fish population, and pelagic species are frequently encountered along this outer exposure — grey reef sharks, silvertip sharks, and eagle rays are regular visitors. The deep outer wall occasionally yields encounters with scalloped hammerheads. Large Napoleon wrasse are unusually approachable at this site, a testament to its limited dive traffic compared to the more heavily visited northern atolls.

Tips for Divers

Advanced divers should manage bottom time carefully on the deeper sections; the wall’s gradient makes it easy to descend beyond planned depths. Addu Atoll’s remoteness — accessible primarily by liveaboard or the domestic airport at Gan — means conditions are infrequently documented, so consult your dive guide’s local knowledge on current direction before entry. Visibility in the 30–40 m range makes wide-angle photography of the wall highly rewarding.
