The Cirque de Mafate is an amphitheatre of walls a thousand metres high on Réunion, holding ten hamlets that no road reaches. It was chosen for exactly that. The cirque carries the name of a maroon leader who hid in it, and behind his name sits the Malagasy word mahafaty, which means that which kills. The cliffs that made it dangerous to enter at all are why the runaways climbed in, and why their descendants still have no road. Fewer than a thousand people live in the îlets, on green shelves under the remparts. Everything they cannot grow arrives on a back or under a helicopter: gas bottles, cement, groceries, every plank of every house.
The gentle door in is the Col des Bœufs. The path drops into the Plaine des Tamarins, a high forest of gnarled tamarin trees trailing pale lichen, and reaches La Nouvelle in about two hours. Past it the waymarked trails carry you îlet to îlet for days, each col opening on a valley deeper than the last. The rim road ends 2,200 metres up at the Maïdo belvedere, straight above the floor. Through the austral winter the cloud off the west coast lies low at dawn, so the roofs and green shelves break through a white lid a kilometre below you. Every drop of water in Mafate leaves through one riverbed, the Rivière des Galets, and so can you, up boulders and braided channels from Deux Bras. Upstream at Trois Roches the river drops into a black fissure in the rock and disappears. In La Nouvelle or Marla your day ends when the light does: dinner at one hour in the gîte, lamps off a solar panel, the wind in the ravine after dark. For forty years the cirque's mail was walked in by one man. Ivrin Pausé left Grand Place on a Monday with fifteen to eighteen kilos on his back and worked the îlets through the week, from 1951 to 1991.
