In the springtime, cool off in the spray created by countless roadside waterfalls or take one of the quick half-mile hikes to the base of Bridal Veil Falls or Yosemite Falls, both just a few miles south of the byway in Yosemite Valley. Enjoy the refreshing spray from both falls in the spring and early summer, for Yosemite Falls often dries up from late July or August through October.
