The Trou de Fer is a canyon on Reunion Island, off the coast of Madagascar in the Indian Ocean. The primary river flowing through the gorge, which is up to 1,000 feet deep, is the Bras de Caverne River, which is a tributary of the Riviere du Mat. The canyon has two distinct parts; a large crater, which is fed by six prominent waterfalls, and a narrow slot canyon at its outlet, which constitutes most of the canyon’s length. The Bras de Caverne River’s headwaters are in a cirque high on the mountainside abutting the canyon wall, and directly after that, it drops over a waterfall about 700 feet high. This drop is usually dry or has very little water, but between that and the next, 600-foot drop, springs feed the river, which drops over this then drops over a final 1,000-foot undercut cliff into the Trou de Fer in a narrow plume of water.
