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).^[1]^[2]

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.^[3]

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		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).^[4]
2		Zhijin Natural Bridge	China, Guizhou, Zhijin Cave Scenic Area	103.6	340	Span measured by NABS, 2015.^[5]
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.^[6]

An earlier non-NABS estimate was 246 ft (75.0 m).^[28]
