Millions of Red Crabs Paint Christmas Island Roads in a Sea of Scarlet

A Stunning Annual Red Wave

Every year, Christmas Island transforms into a breathtaking scene as millions of red crabs move from the forests to the coast. Around 50 million crabs begin their journey from their burrows to the beaches, covering the island’s roads and pathways in a moving carpet of red. This spectacular natural event happens every summer, attracting travelers, scientists, and photographers from around the world.

This year’s migration started in late October and will reach its peak in mid-November when the crabs gather along the coastline to lay their eggs. The sight is one of nature’s most stunning displays, symbolizing the rhythm of life on the island.

Helping Crabs on Their Journey

The islanders take great care to protect the migrating crabs. Authorities have built special crab bridges and tunnels to help them cross roads safely. Local radio stations even give daily updates on the crabs’ movement, reminding drivers to slow down or use alternative routes.

“During migration season, crabs are everywhere — under cars, across roads, even climbing walls,” said one resident, laughing about how daily life completely changes during this period.

According to the video, many people pause their work to watch the fascinating journey that lasts several weeks.

A Natural Wonder Unlike Any Other

Christmas Island, located off the coast of Australia, near Java, Indonesia, is famous for this unique phenomenon. The migration is triggered by the first heavy rains of the wet season, which signal the crabs to move. The red crabs, small yet determined, make their way down steep hills, across jungles, and over human roads to reach the sea.

Once they arrive, female crabs release millions of eggs into the ocean, continuing a life cycle that has taken place for thousands of years. By mid-November, the beaches will turn red again — not just from the adult crabs, but later from millions of baby crabs returning to the forest.

The Island’s Living Treasure

Residents proudly call the crabs their “living treasure.” During migration season, the government even closes some roads to make sure the crabs can pass safely. Visitors are reminded not to touch or disturb them. The sight of so many crabs moving in unison is not only beautiful but also a reminder of how fragile and connected nature can be.

As the event continues through November and December, Christmas Island becomes one of the most extraordinary wildlife destinations on Earth — a true red paradise of motion and life.
