From Le Canon (the next village up) you can catch a boat to Ile aux Oiseaux (Bird Island). This is where you will find the so-called cabanes tchanquées , two picturesque little houses standing on stilts to raise them above the oscillating tide. The cabanes are enchanting in a bizarre kind of way, and they are the very symbol of Cap Ferret. They were built on this shallow spot as a base from which the oyster-men could keep an eye on their watery domain. They are, in other words, watchtowers, constructed to ensure that no conchological scrumper could make off with the lucrative crop.
