In 1805 the frigate HMS Surprise is hammered by a French privateer off Brazil, and her captain will not go home. The chase runs south round Cape Horn to the Galápagos, with a ship's surgeon who only wants to look at birds.
The route follows the film's voyage, then the places where it was actually made: a giant tank in Mexico and the replica ship in San Diego. It covers the 2003 film, not Patrick O'Brian's novels, and the sea stops are left unpinned.
In December 1831 a 22-year-old Cambridge graduate with a passion for beetles and rocks sailed from Plymouth as an unpaid naturalist on HMS Beagle, a ten-gun survey brig. The voyage was meant to take two years and took five. Charles Darwin came home with crates of fossils, skins and notebooks — and with questions about the islands that would lead him, two decades later, to On the Origin of Species.
The route follows the ship around the world in order, using Darwin's own Journal of Researches for dates and details: the volcanic Cape Verde islands, the Brazilian forest, the fossil beds of Argentina, Tierra del Fuego, a great Chilean earthquake, the Galápagos, Cape Town and home to Falmouth.
