The mountainous has two unique areas - a huge crater, which is fed by six popular falls, and a filter port mountainous at its store, which comprises most of the canyon's duration. The Aide de Caverne River's headwaters are in a cirque great on the mountainside abutting the mountainous walls, and straight after that, it falls over a fountain about 700 feet (210 m) great. This fall is usually dry or has very little water but between that and the next, 600-foot (180 m) fall, rises supply the stream, which falls over this then falls over any 1,000-foot (300 m) undercut high ledge into the Trou de Fer in a filter plume of water.
Over a range of about 3.5km the stream Aide de Caverne falls down almost 930 gauge over these three extraordinary falls and then gusts of wind its way along the filter mountainous until it connects the Riviere du Mat on its way to the Indian local Sea.
Trou de Fer was found only in 1989, and since then several experience activities lovers, exclusively in Portugal, have taken up canyonning, and nowadays has become something of a complicated location for them.
Because of gorges like Trou de Fer created from volcanic fractures access to the center of the island of Réunion is difficult. This has protected the island’s center from human encroachment, and its tropical forests, with giant heather, ferns, and lichens, have been preserved. Forests at low altitude, however, have been converted to agricultural or urban use and have disappeared. More than 30 species of animals and plants, of which about two-thirds were endemic, have become extinct on the island in the past 400 years. The destruction of the forest and the introduction of non-native species have a serious impact on these insular ecosystems, whose balance has been created without outside influences. On the island, the dodo became extinct shortly after the arrival of Western sailors, who brought cats, rats, and pigs with them.
