Coco Palm Dhunikolhu’s house reef, measured from satellite rather than described from memory.

Reef cover (modelled)Hard-bottom cover, heat-stress adjusted
3.2
23% of the mapped reef is coral or algae (1.49 km² mapped) · reduced 0.3 for heat stress since the imagery (peak DHW 4.7)
Reef structureThe wall — slope, crest and extent
6.7
31% reef slope (0.45 km²) · reef crest present
Accessibility & easeHow far to the drop-off, and what you cross
9.1
208 m to the drop-off · 35% of the reef is shallow flat to cross

This is Reef Conditions — what a satellite can measure. The full Maldives Index, which adds fish life and big-animal encounters confirmed in the water, has not been awarded to any property yet.

What this is, and isn’t. Measured from the Allen Coral Atlas benthic and geomorphic maps (CC BY 4.0) and NOAA Coral Reef Watch heat-stress records (public domain). Its benthic class is “Coral/Algae” combined — a satellite cannot tell live coral from algae — so this is modelled reef cover, not verified coral health, and never a substitute for being in the water. Imagery vintage 2018-2021; heat stress since then is applied as a penalty.

Documented in Baa Atollcited

Reef manta ray

Overwhelmingly a southwest-monsoon animal here, on the atoll’s eastern flank. Over 95% of acoustic detections at eastern Baa fell in the southwest monsoon, with near-zero activity in the northeast. Across more than a thousand survey days at Hanifaru, feeding was recorded on roughly 62% of them. Hanifaru alone accounted for 64% of detections in its site cluster.

Reef manta ray — the feeding window

Within the season, the timing is tidal rather than merely monthly. Mass feeding is driven by zooplankton concentrated by a back-eddy that Hanifaru’s particular reef shape creates, so spring tides around the full and new moon are the windows that matter. The largest “cyclone” feeding events happen only a handful of times a season.

May–NovSourceArmstrong et al.IUCN SSC 2023

Whale shark

Feeds here in the southwest monsoon alongside the mantas, drawn by the same plankton — but in far smaller numbers than South Ari: on the order of 95 sightings of 53 individuals across a decade.

Before you get in

Pack for this reef.

Chosen from what we measured here — not a generic list.

Mask & snorkel
The one non-negotiable — a well-sealed mask makes or breaks the reef.
Reef-safe sunscreen
Oxybenzone-free — protects you and the coral, and it’s expected on these reefs.
Rash guard / UV top
Hours on the surface add up; covers you and cuts the sunscreen you need.
Fins
The drop-off is about 208 m out — fins make that swim, and holding position in current, far easier.
Dry bag
Keeps phone, room key and a towel dry on the walk out to the reef.

The Reef Code

Non-negotiable. These reefs take decades to grow and seconds to damage — the same rules apply on every reef in the index.

01
Never touch or stand on coral
It’s a living animal — a single footstep can undo decades of growth.
02
Keep your distance from wildlife
No touching, chasing, riding or cornering turtles, sharks, rays or mantas. Hover and let them come to you.
03
Reef-safe sunscreen only
Oxybenzone and octinoxate bleach coral. Cover up with a rash guard where you can.
04
Fins up, float horizontal
One careless fin-kick snaps fragile branching coral and clouds the water for everyone.
05
Never feed the fish
Feeding unbalances the reef and changes natural behaviour for good.
06
Take only photos, leave only bubbles
No collecting shells, coral or sand — living or dead, it stays on the reef.
