This is a survey on a number of different models for random walks: ordinary (simple), self-avoiding (related to polymers); loop-erased walks (related to uniform spanning trees); Laplacian walks. Such walks arise in critical phenomenon. The behavior of the walks depends strongly on the dimension of the space they live.
