Waterfalls in the United States

By total drop, Oloʻupena Falls in Hawaii at roughly 2,953 feet — a sea-cliff fall on Molokaʻi with no trail access, viewable only from the water or the air. On the mainland the tallest is Yosemite Falls in California at about 2,425 feet. Height figures here come from published land-manager and survey records; falls with no measured height are listed without one rather than estimated.

It starts from USGS GNIS named "Falls" features and is cross-referenced against National Park Service, US Forest Service, and state-park land-manager records, plus USGS streamflow where relevant. Every published entry needs a state, a written description, and at least one citation — that floor drops about 152 of the 953 source rows, because a waterfall we cannot cite is not a waterfall we should publish.

No. Trail distance, elevation gain, and a difficulty label describe the route as documented, not conditions on the day. Waterfalls are inherently hazardous — wet rock, cold water, and unstable edges — and flow varies enormously with season and recent rain. Check the managing agency for closures and current conditions before you go.

Because they are part of the same trip. LakeQuality grades lake water quality across the US, and about a third of these falls sit within 25 miles of a graded lake, so the waterfall pages and the lake pages link to each other rather than living on separate sites.
