Gordon Rocks

Gordon Rocks is the best big-animal dive available without boarding a liveaboard: an eroded tuff crater off northeastern Santa Cruz whose rim breaks the surface in three stacks. Inside, the crater floor sits around 32 m; the action concentrates along the rim, where scalloped hammerheads patrol singly or in small schools and eagle rays hold formation against the flow. Sea lions dive-bomb safety stops, turtles wedge into the rock to be cleaned, and the current - the site's engine and its hazard - can shift mid-dive. Locals call it the washing machine without exaggerating much. Day boats run it regularly from Puerto Ayora, making it many divers' first hammerhead encounter.

اللحظة التي جئت من أجلها: Hammerheads on a day trip, eagle rays stacked in current, sea lion buzz-bys

التضاريس: Submerged volcanic crater rim with sand at depth inside

التيار: The eroded crater funnels tide through gaps in the rim - down-currents happen, which is why day boats vet experience.

المخاطر: Down-currents and washing-machine turbulence at the rim gaps; surge near the stacks.

الحفاظ على البيئة البحرية: Within the Galapagos Marine Reserve; guided groups only.

نيتروكس: يستحق الأمر هنا: الملفات الشخصية تقع في النطاق الذي يُمدّد فيه الهواء المدعّم (نيتروكس) وقت الغوص دون توقف تمديدًا ملموسًا، مع التدريب اللازم لاستخدامه.
