Pulu Keeling National Park

Twenty-four kilometres north of the inhabited atoll, North Keeling rings its lagoon as Pulu Keeling National Park - the group's sanctuary absolute, uninhabited and landing-restricted, where the seabird metropolis compensates the emptiness: red-footed boobies in tens of thousands, frigatebirds, terns and the endemic Cocos buff-banded rail holding its recovered numbers on the one ring where cats and rats never ruled. The park's history includes the SMS Emden's 1914 end on the reef - the wreck's remnants a protected footnote. Landings run rare, permitted and swell-dependent through the park's arrangements; the sanctuary's point is precisely how seldom.

What you actually see

• The booby metropolis - tens of thousands on the ring.
• The endemic rail - the recovered island survivor.
• The sanctuary lagoon - the closed ring's green-blue heart.
• The Emden footnote - the 1914 wreck's protected trace.

When to go

April to October in principle - permits, park arrangements and swell govern the rare landings entirely.

Honest expectations

Access is deliberately exceptional - most visitors meet the park as a horizon and a story; that scarcity is the conservation working.
