Savor the sights, beat the heat, and add a splash of adventure on a rafting trip through Yosemite Mariposa County. Find flow while drifting quietly downriver past famous Yosemite landmarks on a scenic float trip. Or brace yourself for a thrilling ride through Class IV whitewater just outside Yosemite along Highway 140. Yosemite rafting is clearly the coolest game in town for summer fun.
