The Yosemite Area Regional Transportation System (YARTS) provides public fixed route transit service into Yosemite National Park (YNP), covering a 480-mile service area. Since its initial services began in May 2000, YARTS has grown into a vibrant and extensive public transit system. The transit service is important to various “Gateway Communities” in the adjacent counties including Sonora, Merced, Fresno, and Mammoth Lakes. YARTS operates as a thruway bus service for Amtrak and the interline bus service for Greyhound.
 

Ridership has grown by approximately 50% over the last 20 years and includes both visitors to the park as well as National Park Service (NPS) employees. Ridership also consists of passengers who use the service to reach the City of Merced for shopping, academics (Merced College and UC Merced), recreation, medical appointments, and other transportation connection services.
