Self-avoiding walks (SAW) explore the backbone of a fractal lattice, while random walks explore the full lattice. We show the existence of an intrinsic exponent for SAW and examine a simple Flory approximation that uses the spectral dimension of the backbone. Exact results for various fractal lattices show that this approximation is not very satisfactory and that properties of SAW depend on other intrinsic aspects of the fractal. Some remarks are presented for SAW on percolation clusters.Les marches sans retour (SAW) explorent le « squelette » d'un réseau fractal, a la différence des marches aléatoires.
