The Eastern Sierra Transit Authority (ESTA) was established in November of 2006 as a Joint Powers Authority between the Counties of Inyo and Mono, the City of Bishop and the Town of Mammoth Lakes. ESTA was   created to meet the growing need for public transportation in and for the four member jurisdictions and throughout the entire Eastern Sierra region.

ESTA offers a variety of bus services, including; deviated fixed routes, local in-town dial-a-ride services,multiple town-to-town services throughout the Hwy 395 and Hwy 6 corridors, and interregional service (CREST) extending from Reno, Nevada to Lancaster, California with connections to the Los Angeles area.The ESTA Board of Directors is made up of eight members, two from each of the member jurisdictions, appointed from their respective governing bodies. ESTA began operating transit services on July 1 of 2007, assuming control of all the services, staff and capital formerly known as Inyo Mono Transit(a division of Inyo County government).
