From March to June the waterfalls at Yosemite National Park are spectacular after a solid season of snow which melts and comes rushing down the mountains. The park contains 7 major falls you can watch:

Bridalveil Fall  620 feet in height, the wind often blows sideways, fanning the misty spray to the shape of a bride's veil, thus the name.

Ribbon Fall is the tallest waterfall in North America, cascading 1,612 feet or more than 1/3 mile from its highest point to the valley floor. 

Yosemite Falls measures 1,430 feet in its upper portion;  675 feet in the middle, and 320 feet as it hits the rocks and ground running. The spray from the fall spreads out and will get your camera, hair and clothes wet. Its total drop of the three combined segments is 2,425 feet, and it ranks as one of the tallest waterfalls in North America and fifth highest in the world.
