Vernal Fall is a 317 ft (97 m) tall waterfall on the Merced River just downstream of Nevada Fall in Yosemite National Park, California, United States. It is accessible via the Mist Trail, which climbs close enough to the fall so that hikers must travel through the fall's mist. The waterfall runs all year long, although by the end of summer, it is substantially reduced in volume and can split into multiple strands, rather than a single curtain, of water.Photo credit: God of War
