Witness one of the most amazing events on our animal planet, as 60 million Red Crabs migrate from the forest to the ocean shoreline to mate and spawn each wet season in November or December.

  • Experience the peak of what Christmas Island has to offer with this special package which is only offered on specific dates each year and subject to the rains starting allowing the crabs to move to the lower terraces.

  • The red crab migration commences with the start of the wet season. Red crabs use a very distinctive phase of the moon to spawn. This bucket-list event usually takes place across two mornings in November or December.

Itinerary

Tour day-by-day

  • Red Crab Spawning Event

    Please note that the exact date of the spawning tour as part of this package will be determined immediately prior to the spawning event. Participants will be contacted upon arrival if any changes are required to the date of operation of the spawning experience.

    Details of the Migration

    At the onset of Christmas Island's wet season (which can be early as mid November), the crabs are triggered to abandon their burrows on the top plateau and head down to the lower terraces for mating. Generally the males set off first, with the females following a few days or a week later.

    This part of the migration is very unpredictable and dependent on the start and continuity of the seasonal rains. The migration may become sporadic or stop if the rain stops. If the conditions are right, the crabs can be viewed migrating in the mornings (before 10am) and in the later part of the afternoon (3.30pm onwards).

    There are a few key locations close to the township where the crabs move and the Indian Ocean Experiences' team will advise you of these. There could be a window of 10-14 days of crabs on the move, again, dependent on the rains.

    If you plan to travel for this part of the migration, we recommend a minimum 7 day stay to increase your chances of a successful viewing. Crabs may be viewed on a suite of Indian Ocean Experiences tours.

    The Spawning

    This element of the migration is predictable, as the female crabs need to drop their eggs into the sea using very specific tides, which can be predicted. There are generally two consecutive mornings in November and/or December. The dates change each year and where these tides fall in the month determines the greater likelihood of there being either a November or December spawning, or possibly both months.

    The Red Crabs start dropping their eggs around 4am, and stop as the sun rises. Once they have delivered their spawn to the sea, they then head back up to the forest. Spawning tours can only be operated on the mornings of those specific dates. A shorter stay on the island is possible, depending on the flight options.

    The Red Crab Migration Sequence

    1) Males start migrating to the lower terraces and dig burrows (approx. 4 weeks prior to predicted spawning dates).
    2) Females migrate to the lower terraces and mating takes place (approx. 2 weeks prior to spawning dates).
    3) Males then leave the females in the burrows to gestate the egg mass and migrate back to the upper terraces.
    4) Females deposit eggs into the ocean on the spawning dates and migrate back to the upper terraces. 
    5) Approx. 21 days after spawning event, baby red crabs may return en masse.
