Red crab migration
15 Oct – 15 Jan · usuallyWildlife seasonClosuresBook earlyMillions of crabs leave the forest with the first rain and walk to the sea, and the cove is one of the easiest places to stand in the middle of it. Roads close at short notice, spawning happens before dawn on the last quarter of the moon, and the start date moves with the rain. Source ↗
- Hazard
Cyclone season
1 Nov – 30 Apr · usuallyClosuresStorms in the wet half of the year bring big seas into the cove, which is the island's only sheltered landing. When the swell is up the cargo cannot come off and the boat dives stop. Source ↗

Baby crabs come ashore
20 Nov – 20 Feb · usuallyWildlife seasonAbout a month after spawning the young crabs come out of the sea and head inland in a red carpet a few centimetres deep. In a good year it is the better half of the spectacle, and in a bad one it barely happens. Source ↗
