These waterfalls inside a canyon are among the most spectacular on the island, with numerous individual cascades plunge into an almost circular basin that is only open on the north side, around 200 metres in diameter and several hundred metres deep. The boiler is not accessible for "normal tourists" but there is a lookout point at the top of the Kessel and with access from the hiking trail in Forêt de Bélouve that shows part of the waterfalls. During the helicopter tours, the narrow basin is flown through spectacularly from bottom to top as a spiral. A robust stomach is required, the helicopter pilots show all their skills.
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 300 m (1,000 ft) deep, is the Bras de Caverne River, a tributary of the Rivière du Mât. 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 canyon starts at the waterfall of the Bras Mazerine stream and after some 1.4 – 1.8 km from the left side joins the main Bras de Caverne stream. The Bras de Caverne River enters the canyon with a waterfall about 200 m (660 ft) high. This drop is usually dry or has very little water, but between that and the next, 180-metre (590 ft) drop, springs feed the river, which drops over this then drops over a final 300-metre (1,000 ft) undercut cliff into the Trou de Fer in a narrow plume of water.
