La Fou is an old Catalan word meaning precipice, but when you first arrive, you have no idea of the amazing sheerness of the walls of this gorge.
It is said to be the narrowest gorge in the world, and in some parts the walls are only about 1 meter apart, with a depth of between 200 and 250 meters.
The gorge stretches for about 1739 meters and the constructed metal passageway allows one to walk 1500 meters of its length. There is an incline of about 9% giving a rise of 157 meters from the beginning of the walk to its end. The average time needed for a visit, is between one and a half to two hours. The metal passageway passes over the stream throughout its length. It is the constant flow of this stream that has cut the gorge, and the numerous galleries and caves. The water continues to erode the calcified rock base. It is said that bandits used the gorge as a hide away, more than 100 years ago, but it was not until 1928 that a group of local people explored the full length of the canyon for the first time.
