One of the first waterfalls you are able to stop and visit in Yosemite National Park (at least easily) as you enter on CA-140 is Wildcat Falls. You cannot actually see the portion of the falls in the picture here, but instead the upper portion. It is possible to photograph the upper portion, but not together with the lower portion. The upper portion is further away, so I haven’t included it here. The lower portion has a little bit more character. As usual, I assume this waterfall might just disappear later in the summer.
1) Enter the park on CA-140 heading east. Pay the $20 entrance fee.
2) After driving a short ways into the park, you should see Wildcat Falls on your left. It drops from a cliff. There is a pullout on your left, and a very short trail leads to the lower portion of the falls.
