Wood chips are good for pathways along a garden in that they are durable and prevent compaction from foot traffic. Natural colored chips can also make the path blend in with it's surroundings.
Adding chips to the landscape can be a good thing. There are some benefits to keep in mind. Mulch is a material placed over the surface of the soil for a number of reasons. As mulch, the wood chips will reduce germination of weed seeds, stabilize soil temperatures (warmer in winter, cooler in summer), reduce evaporation and conserve soil moisture, and make removal of weeds easier. Wood chip mulch can be attractive when used properly in the landscape.
