Yosemite Falls, USA

Yosemite Falls in Yosemite National Park, California, is North America's tallest waterfall, dropping 739 metres total across three sections: Upper Yosemite Fall (435 m), the Middle Cascades (206 m), and Lower Yosemite Fall (98 m). The falls are fed entirely by snowmelt and dry up almost completely by late summer in most years, making April–June the optimal viewing window when Sierra Nevada snowpack drives peak flow. The Lower Fall trail (2.6 km round trip) is accessible to most visitors and delivers a thunderous base-of-falls experience; the strenuous Upper Fall trail (11 km) reaches a viewpoint looking directly into the granite valley with Half Dome visible across the valley floor.
