Stepping stones or stepstones are sets of stones arranged to form an improvised causeway that allows a pedestrian to cross a natural watercourse such as a creek, a small river; or a water feature in a garden where water is allowed to flow between stone steps.^[1] Unlike bridges, stepstone crossings typically have no spans, although wood planks or stone slabs can be placed over between the stones (which serve as the piers) to improvise as low-water bridges. Although their historical origin is unknown, stepping stones, along with log bridges, are likely to have been among the earliest means of crossing inland bodies of water devised by humans.

In traditional Japanese gardens, the term iso-watari refers to stepping stone pathways that lead across shallow parts of a pond, which work like a bridge-like slower crossing. Using iso-watari for crossing ponds, or shallow parts of streams, one can view the aquatic animals and plants around or in the pond, like carp, turtles, and waterfowls.

Today, stepping stones are commonly used by mountaineers and hikers as a makeshift way of crossing uncharted or unanticipated streams and torrents. They may occur alongside a ford.
