The program, which begins Friday, will allow visitors to park their cars and take a bus run by the Yosemite Area Regional Transportation System or Y.A.R.T.S. from El Portal along highway 140 and into Yosemite Valley.
Yosemite Park's Kari Cobb says the program will do more for visitors than just relieve traffic stress.
KARI COBB: "You're free to see the waterfalls and see the granite that's around here. Driving through the park you can tell when somebody's brand new cause they're swerving all over the road, they're looking up. So if they take YARTS in they can just spend the entire ride looking at the sights along the way."
The bus service costs 7 dollars for adults, 5 dollars for kids under twelve, and will be offered on weekends through Labor Day.
Last year more than 4 million visitors toured Yosemite National Park, the first time since the mid 90's that visitation has reached the 4 million mark.
