Darwin's Arch (Darwin's Pillars)

The famous rock arch beside Darwin Island collapsed in May 2021, leaving two pillars, but the dive below never depended on the architecture. Divers drop onto a boulder platform at 12-20 m nicknamed the theater, brace against the current, and watch the eastern Pacific commute past: scalloped hammerheads in ranks, Galapagos sharks quartering the edge, turtles laboring across the flow. In the cool season the main event arrives from the blue - whale sharks, most of them enormous females, that pass the platform on patrol. The ascent drifts into open water, blue and bottomless, which is where safety-stop silkies like to make their inspection.

El momento por el que vienes: Whale sharks June-November, walls of hammerheads, Galapagos sharks at arm's length, dolphin flybys

Topografía: Sloping boulder platform ending in a drop to deep water

Corriente: Current sets the plan; divers wedge in behind boulders on the platform, then drift off into the blue for the ascent.

Riesgos: Strong current, surge over the platform, blue-water ascents far from the boat; panga pickups require a DSMB.

Conservación: Within the Galapagos Marine Reserve; no contact with the reef, and only permitted liveaboards may dive here.

Nitrox: Vale la pena aquí — los perfiles se sitúan en el rango donde el aire enriquecido (nitrox) amplía de forma significativa el tiempo sin descompresión (con la formación necesaria para usarlo).
