There are lots of swimming spots in spring and summer in Yosemite Valley along the Merced River. One of my favorites is the sandy beach near Sentinel Bridge, with its lovely view of Half Dome. When the water level is high enough you can also swim in Tenaya Creek and Mirror Lake.
Decide what time of year you will go. This depends on what you want to see or do in Yosemite. Roads to the valley (but not to other areas of the park) are open all year. Spring: April to early June is the best time to see the waterfalls. The weather can vary during this time. Crowds are light, except on May weekends.
