The Lower Yosemite Fall Trail at Yosemite National Park is a short, highly-trafficked, 0.9 mile hike out to the Lower Yosemite Falls. Yosemite Falls, in its entirety, is 2,425 feet and flows from November through July with its peak in May. Yosemite Falls is one of the world's tallest waterfalls and is made up of three
separate falls: Upper Yosemite Fall (1,430 feet), the middle cascades
(675 feet), and Lower Yosemite Fall (320 feet). This trail brings you to the Lower Yosemite Falls portion, but you get views of the entire falls from almost immediately at the trailhead.
Parking can be found across the street from the trailhead and is usually accessible, despite the large crowds at the park. The trail itself is highly trafficked, but is still enjoyable, especially just below the falls.
If you arrive in late Summer, the falls may be dried up as it tends to dry up by July. This trail is also very accessible since it's mostly flat and paved or crushed stone.
