Pitcairn is the least populous territory on Earth: about 35 people live on 4.6 square kilometres of volcanic rock, and most of them descend from the men who mutinied on HMS Bounty. Fletcher Christian and eight fellow mutineers landed in January 1790 with six Tahitian men, eleven women and a baby girl, then burned the ship in the bay below the village so nobody could leave and no passing sail would see her. The island was charted in the wrong place, and the outside world took eighteen years to find them. Polynesians had lived here centuries earlier and vanished, leaving carvings on the cliff at Down Rope. Today Pitcairn is Britain's last territory in the Pacific, and its hardest problem is arithmetic — the population peaked at 233 in 1937 and has drained away to New Zealand ever since, so the government now offers free land to anyone willing to settle.
A supply ship crosses from Mangareva in French Polynesia, roughly 32 hours at sea, about two dozen times a year, and there is no harbour at the end of it: an aluminium longboat waits for the right breaker and rides it through a gap in the rocks into Bounty Bay. If the swell is wrong, the landing is called off with the island in plain sight. Ashore, it is steeper and greener than its size suggests — banyan and breadfruit climb to a ridge 347 metres up, and black cliffs drop into deep water. On the east coast, St Paul's Pool sits behind a wall of basalt spires, the ocean bursting through a channel into water clear enough to swim in. The sea around the island is one of the planet's largest marine reserves, and no town glows anywhere against its sky. Each austral winter, humpback whales come in under the cliffs to breed.
