List of longest natural arches

This list of longest natural arches ranks the world's natural arches by the length of their span as reported by the Natural Arch and Bridge Society.

As a disclaimer, the NABS states that the information in this list, and therefore the rankings, are subject to change due to a variety of reasons that may include updated measurements, changes in span due to natural forces, and the discovery of previously unknown arches.^[1]
