Trou de fer - Canyoning on Reunion island

Trou de fer is THE big canyon of the island... the picture of the "hole" is famous all around the world and you can see it getting out of the airport or on the door of the bakery when you go to get some bread for your breakfast, but few people really went down to this hole, and you need very good physical condition and experience on rope if you want to be one of these few people.
