The reef at Gan’s island — shared by 5 properties here. Every guesthouse on this island snorkels the same reef, so we score the island, not the doorstep.

Reef cover (modelled)Hard-bottom cover, heat-stress adjusted
3.8
28% of the mapped reef is coral or algae (3.14 km² mapped) · reduced 0.4 for heat stress since the imagery (peak DHW 5.1)
Reef structureThe wall — slope, crest and extent
6.8
30% reef slope (1.05 km²) · reef crest present
Accessibility & easeHow far to the drop-off, and what you cross
6.2
526 m to the drop-off · 42% 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 Laamu Atollcited

Grey reef shark

Laamu Maavah Kandu is a year-round cleaning area, recorded across several hundred surveys, and also holds an aggregation of silvertip sharks.

Year-roundSourceIUCN SSC 2023
Not established here honest

Turtles — no atoll-level seasonal study exists; treat them as year-round residents rather than a season

Mantas — reported at Fushi Kandu in the southwest monsoon, but not from an assessed source we can stand behind

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 526 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.
