# List of longest natural arches

This list of longest natural arches ranks the world's natural arches by the length of their span as defined and measured by the Natural Arch and Bridge Society (NABS).
As a disclaimer, the NABS states that the information in this list, and therefore the rankings, may change due to more accurate measurements in the future, changes in span length due to natural forces, and the discovery of previously undocumented arches.

## Longest natural arches

All known natural arches with span lengths of 180 ft (54.9 m) or greater are included in the list. Sort by clicking on column headings, excepting only the Image and Notes columns.
| Rank | Image | Name | Location | Span (m) | Span (ft) | Notes |
| 1 | external image | Xianren Bridge (Fairy Bridge) | China, Guangxi, Buliu River | 121.9 | 400 | Span measured by Natural Arch and Bridge Society (NABS) in 2010. The accuracy is stated as within ±15 ft (4.57 m). |
| 2 | external image | Zhijin Natural Bridge | China, Guizhou, Zhijin Cave Scenic Area | 103.6 | 340 | Span measured by NABS, 2015. |
| 3 | | Jiangzhou Natural Bridge | China, Guangxi, Jiangzhou | 94.5 | 310 | Span measured by NABS, 2010. Estimates range from 280 ft (85.34 m) to 340 ft (103.6 m), so the midpoint is listed, ±36 ft (11.0 m) which includes a ±6 ft (1.8 m) accuracy above/below the higher/lower estimate. Jiangzhou ranks somewhere between 2nd and 6th position based on current estimates. |
