Frequently Asked Questions
How many waterfalls are there in
USGS GNIS records 70 named waterfalls in Idaho. The true count is higher once you include unnamed seasonal cascades, but 70 is the official federal tally of falls notable enough to carry an established name.
Which county has the most waterfalls in
Twin Falls County leads with 8 named falls, followed by Boundary County (6) and Bonner County (6). The full county breakdown is in the table above.
Are these Idaho waterfalls accessible to visit?
Most named falls in Idaho sit on publicly accessible land — state parks, National Forest land, BLM tracts, or county/municipal property. Some are on private land or tribal land with their own access rules. Always check the relevant land manager before visiting, and never trespass. The driving-directions link in each map popup takes you to the nearest road; some falls then require a short or moderate hike.
When is the best time to visit Idaho waterfalls?
For most of Idaho, peak flow is during spring snowmelt and after heavy rains; late summer and early autumn typically give lower but clearer flow with better foliage colour. In high-elevation parts of the state, many falls partially freeze in winter and become spectacular ice formations.
Where does this data come from?
The USGS Geographic Names Information System, the federal standard for U.S. place names since 1890. We queried The National Map’s ArcGIS REST service in May 2026 for every feature classified as Falls within Idaho. GNIS does not record waterfall heights — for that, see the World Waterfall Database.
