Darwin Island
Ecuador · Galápagos
Darwin is the northernmost island in the Galápagos archipelago and one of the planet's elite shark sites — schooling hammerheads, Galápagos sharks, silkies and whale sharks (in season) move along a single submerged arch. There's no land diving here; access is liveaboard only on a tightly regulated permit system.
How this reef is doing
ⓘ How we measure thisReef state
Surveys at Darwin and Wolf recorded the highest reef fish biomass yet measured on any reef, 17.5 tonnes per hectare, of which 12.4 tonnes per hectare was sharks, the greatest shark biomass on Earth (Salinas de León et al. 2016); the state shown reflects coral under recent heat stress, not the fish community that protection keeps world class.

Heat
Warmer than usual right now, but not hot enough to bleach.
Fishing
Quiet water, and fishing is fully banned here.

Fish abundance
Fish seen per survey
Across 8 years of REEF volunteer surveys around Darwin Island (Galápagos), divers have recorded a steady amount of fish per survey. This tracks fish life, standardised for survey effort, so we keep it separate from the coral read above.

What divers say
Hooked into the reef at Darwin's Arch with a wall of hammerheads above me, I forgot to breathe for a second. That's not a metaphor.
Good to know
Permit limits
Only a handful of vessels are permitted at Darwin/Wolf. Book 12–18 months ahead.
Arch collapse
The iconic arch collapsed in 2021. The dive site is unchanged; the silhouette isn't.
