Christmas Island blowholes
In the jagged limestone along the south-western coast of Christmas Island have formed numerous noisy blowholes. The sight is even more impressive during the mass migration of red crabs.

The Dales of Christmas Island
Seven deep valleys formed by spring streams, closer to the sea turning into deep ravines cut in limestone. Above, at the discharge of springs they have flooded the forest dominated by enormous Tahitian chestnuts (Inocarpus fagifer). These pools in the forest form the largest freshwater basin on the island. Endemic plants.
Hosnies Spring mangroves
120,000 years old grove of mangroves some 24 – 37 m above the sea level. Mangrove ecosystems traditionally grow in shallow seawater – but here, as the sea level decreased, mangroves were fed by springs. This is unique case in the world. This 3,300 m² large area (core part, 202 ha in size) contains the oldest trees of Bruguiera gymnorrhiza and Bruguiera sexangula – 30 – 40 m tall, with trunk diameter up to 80 cm. There are mangroves of other species growing well above the sea level elsewhere on the island.
Christmas Island crab forest
The forest of Christmas Island is unique in the world due to dominant species – some 50 – 100 million red crabs (Gecarcoidea natalis) – clearing the forest floor of leaves and other organic matter. These crabs are endemic to Christmas Island. Once per year they migrate to the sea to lay their eggs, on the way blocking the roads and paths.
