Since 1980 I have visited Yosemite many times, at least once in each of the four seasons. It is a spectacular park that would require a lifetime to explore completely, and would be well worth the effort.

If you are into waterfalls and cascades, the spring and early summer are the best times to visit. The winter snow melt provides an overwhelming abundance of water to feed the streams that eventually pour over the granite surfaces of Yosemite Valley, and other areas, to produce the wild falls. Even in dry years there is water year-round over many falls, but when it has been dry, and in the late summer and autumn, there is not the volume one might desire. And many of the more famous falls, such as Yosemite and Bridalveil, are often dry by the end of the season. In the spring many of the lowland areas become flooded, or are quite marshy. Always check with the rangers before heading down a trail.

In the winter and early spring, when much of the surface is covered in snow, there are different attractions. But even in the warmer months the nights can get cold. The elevation throughout most of the park is high and temperatures can drop quickly. Be prepared with clothing for a variety of seasons and weather conditions.
