These stepping stones are frequently used by pedestrians from Rathfarnham and Churchtown to access Bushy Park in Terenure. However, if the water level is high the route becomes unusable but there is now a new footbridge nearby.
Stepping stones or stepstones are sets of stones arranged to form a simple bridge or causeway that allows a pedestrian to cross a natural watercourse, such as a river; or a water feature in a garden where water is allowed to flow between stone steps. Unlike other bridges, they have no spans. Although their origin is unknown, stepping stones, along with log bridges, are likely to have been one of the earliest forms 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. Using iso-watari for crossing ponds, or shallow parts of streams, one can view the fish and plants around or in the pond, like carp, turtles, and waterfowls. It works like a bridge, in a slower way of crossing.
