Witness one of Earth's most jaw-dropping natural spectacles — millions of scarlet red crabs flooding the forest floor, roads, and cliff edges on their annual march to the sea. A once-in-a-lifetime phenomenon found nowhere else on the planet.
What to expect
Your guide leads you through the national park to the seasonal hotspots where the crab tide is most concentrated, explaining the extraordinary biology and lifecycle behind the migration. You'll stand mere inches from an unbroken river of red as crabs stream past your feet and down cliff faces into the turquoise ocean below. The sensory experience — the rustle, the colour, the sheer scale — is utterly overwhelming in the best possible way. Numbers are strictly limited to preserve the environment and your experience.
Good to know
The migration is seasonal (typically October–January, peaking around the full moon after the wet season begins) — confirm active migration dates before booking. Pre-book directly as soon as your port call is confirmed; spots sell out months in advance. Allow the full day ashore; all-aboard times on tender ports like Christmas Island require careful planning — confirm with your ship and allow a 90-minute buffer.
