Christmas Island
TerritoryAdministered by: Australia
“Fifty million red crabs cross a road once a year, and the roads close for them.”
Once a year, usually in October or November after the first rains, tens of millions of red land crabs leave the forest of Christmas Island and walk to the sea to spawn. Roads close, bridges and underpasses are built specifically for them, and the island turns red. David Attenborough has called it one of his greatest natural-history experiences, and it is the reason most visitors come.
The island is an Australian external territory 350 kilometres south of Java and 1,550 from the Australian mainland, with about 1,700 people — a mix of Chinese, Malay and European descent from the phosphate-mining era, giving it temples, mosques and a church within a few kilometres. Two-thirds is national park: rainforest on a limestone plateau, seabird colonies including the endemic Abbott's booby, whale sharks offshore, and drop-offs a short swim from the shore. It also housed an immigration detention centre for years, which is part of its recent history.
Highlights
The red crab migration
Tens of millions of crabs move from forest to sea after the first rains, usually October or November, timed to the lunar cycle. Roads close, purpose-built crab bridges carry them over highways, and the whole island reorganises around it.
Whale sharks
Whale sharks arrive around the same time as the crab spawn, feeding on the eggs washed into the sea — roughly November to April, with snorkelling trips run under strict rules.
The Dales and Hugh's Dale waterfall
Freshwater springs emerging through the limestone into rainforest on the western side, with a boardwalk through a grove of tall pandanus to a waterfall that runs after rain.
The seabird colonies
Abbott's booby breeds nowhere else on earth, alongside the Christmas Island frigatebird and golden bosun. The forest canopy holds nesting sites within a few metres of the road.

Where this sits among 244 countries we have costed
The crab migration in October and November books out accommodation and flights months ahead. The dry season from April to September is quieter and easier to arrange.

The plateau
National park rainforest, Abbott's booby nesting canopy and the crab routes down to the sea.
Practical guide
Getting there
Virgin Australia flies from Perth, sometimes routing via the Cocos Islands, a few times a week. Schedules are thin and weather or maintenance can strand you for days.
Getting around
A hire car — ideally a 4x4 — is essential; many of the best sites are down unsealed tracks that require one, and rental companies enforce that. There is no public transport.
Money & costs
Australian dollar. Cards work at most businesses. Groceries are expensive; the supply ship arrives every few weeks and fresh produce is best just after it does.
Safety
Very safe. The hazards are the cliffs, strong currents outside the coves, and driving on unsealed tracks. During the migration, crabs make roads genuinely slippery and closures are enforced — driving over crabs is both illegal and unpopular.
Health
A small hospital handles routine care; anything serious is flown to Perth, which takes hours. Travel insurance covering evacuation is essential. No malaria; dengue occasionally.
SIM & internet
Telstra provides coverage in the settled areas. Australian plans work at domestic rates. Data is functional in Flying Fish Cove and patchy across the plateau.
Driving
Left-hand traffic. A 4x4 is needed for most national park tracks and rental agreements specify which roads a 2WD may use. During the crab migration whole roads close for weeks and driving over crabs carries a fine.

Christmas IslandFrequently asked questions
When exactly is the crab migration?
Usually late October to early December, triggered by the first substantial rains and timed so that spawning happens before dawn on a receding high tide in the last quarter of the moon. The Parks Australia crab report predicts the dates a few weeks out — book flexibly, because the exact week moves year to year.
How do I get there?
Virgin Australia flies from Perth a couple of times a week, about four and a half hours, sometimes via the Cocos Islands. There is occasionally a service from Jakarta. That schedule means a stay of three or four days, or a full week — and cancellations happen.
Do I need an Australian visa?
Yes. Christmas Island is Australian territory for immigration, so the same eVisitor, ETA or visa applies as for the mainland, even though flights from Perth are domestic. Biosecurity is separately strict in both directions.
