Waterfalls in United StatesUnited States

American waterfalls fall into a few distinct families shaped by geology. Yosemite's granite cliffs in the Sierra Nevada produce free-falling giants such as Yosemite Falls, Bridalveil Fall, and the paired drops of Nevada and Vernal Falls along the Mist Trail. The Columbia River Gorge and Cascades, cut through layered basalt from ancient lava flows, feed Multnomah and Snoqualmie Falls. The Appalachians, from Georgia's Amicalola and Toccoa Falls to New York's Taughannock and Letchworth falls, sit in some of the oldest, most eroded terrain in North America. Hawaii's volcanic streams add Akaka and Wailua Falls in the tropics. One oddity: Ruby Falls, in Tennessee, is the tallest waterfall open to the public that never sees daylight, hidden hundreds of feet inside a limestone cave.

When to go

Sierra Nevada falls run heaviest with spring snowmelt in May-June and can thin to a trickle by September. Pacific Northwest falls stay strong through spring and pick up again with autumn rain. Appalachian falls are steadiest in spring and after autumn storms. Hawaii's falls run year-round off consistent trade-wind rain.

Getting around

Self-driving covers almost all of these falls, especially in the Appalachians and Pacific Northwest, where park roads reach close to the trailheads. Yosemite and other busy parks require parking permits or shuttles in peak season. Havasu Falls needs a permitted backpacking trip or helicopter. Hawaii's falls are reached by rental car.

Entry requirements

Canadians enter the US visa-free with a valid passport; UK and most EU visitors travel under the Visa Waiver Program and need an ESTA (US$40 since September 2025, valid up to two years), including at land crossings from Canada.
