Yosemite Falls (2,425 feet)

Flows: approximately November through July, with peak flow in May.

Look for the ice cone at the base of the upper fall during winter and for roaring runoff April through June. Yosemite Falls, one of the world's tallest, is actually made up of three separate falls: Upper Yosemite Fall (1,430 feet), the middle cascades (675 feet), and Lower Yosemite Fall (320 feet).

You can see Yosemite Falls from numerous places around Yosemite Valley, especially around Yosemite Village and Yosemite Lodge. A one-mile loop trail leads to the base of Lower Yosemite Fall (the eastern side of the loop, from the shuttle stop to the base of the waterfall, is wheelchair accessible).

It's also possible to hike to the top of Yosemite Falls as a strenuous, all-day hike

Hiking:

Lower Yosemite Fall (easy, but icy in winter)

1 mile/1.6 km loop; 30 minutes [half of loop wheelchair accessible] [leashed pets allowed]
Begin at the Lower Yosemite Fall Trailhead (shuttle stop #6)

This short, easy walk rewards with spectacular views of Upper and Lower Yosemite Falls. This waterfall is often dry from late July or August through October. However, expect spray in spring and early summer.

Upper Yosemite Fall (strenuous, but difficult in winter due to snow, especially beyond Columbia Rock)

7.2 miles/11.6 km round-trip; 6 to 8 hours; 2,700 feet/823 m elevation gain

Begin at the Yosemite Falls Trailhead, Camp 4 (shuttle stop #7)

One of Yosemite oldest historic trails (built 1873 to 1877), the Yosemite Falls Trail leads to the top of North America’s tallest waterfall 2,425 feet (739 m) above the Valley floor. Do not stray off the marked path, as you will find steep drops adjacent to the trail. Enjoy spectacular views from Columbia Rock located one mile (and dozens of switchbacks) from the trailhead.
