EL ARCO

El Arco (The Arch) is an advanced dive to 18 meters featuring a spectacular natural rock arch formation on Chile's central coast near Algarrobo. The underwater arch creates a dramatic swim-through where currents concentrate marine life, with the structure covered in dense anemone colonies and encrusting organisms. Large conger eels and octopus shelter in the surrounding crevices, while schools of fish swirl through the arch opening. Strong surge and current conditions demand advanced skills to fully appreciate this architecturally stunning Chilean Pacific dive site.
