YARTS is the local Yosemite National Park public transportation with a stop at the entrance to AutoCamp. The daily YARTS shuttles can pick you up at the AutoCamp entrance and take you straight into Yosemite National Park valley floor. You can also drive from AutoCamp Yosemite into Yosemite National Park.
The YARTS shuttle schedule changes seasonally. You can see up-to-date shuttle times here.
