Vernal Falls is a powerful, 310-foot waterfall located in Yosemite National Park in California, USA. It is one of the most iconic and dramatic waterfalls in the park. It can be reached via a series of steps along a well-maintained, moderate but steep trail, and offers spectacular views of the canyon, river and valley below. The trail is a series of switchbacks starting near Happy Isles, leading up to an overlook of the cascade. It is a popular destination for hikers and photographers alike, as the thunderous roar of the falling water and the airbrushed spray of the mist is truly remarkable. However, it is important to heed signs and safety precautions, as the terrain can be slippery at times.
