Lower Yosemite Falls
The Lower Fall is 320ft and has a viewing area near the base. Although you may be tempted, do not get too close as the rocks near the base are sharp and very slipper (not to mention there is a water falling powerfully from above).
There is a viewing area where you may find it difficult to keep crowds of tourists out of your perfect pictures on crowded summer days. You can also cross the wooden footbridge to explore the area further.
