Spring Service Changes – Mammoth

Effective Monday, May 2nd, ESTA and Mammoth Area Transit will transition into Phase 2 of the 2016 spring transit service. This change will include the cessation of service of the full Red Line and the start of the day time Trolley service. The Trolley will operate from 7:30am until 10:00pm from May 2nd until Memorial Day (anticipated). During this period, Mammoth Mountain Ski Area will operate a shuttle service between The Village and Main Lodge from 7:45am until 4:45pm.

Swiftly – Real-Time Bus Information System in Testing

ESTA is in beta-test mode with a new real-time bus information system, which is expected to be functional and available in Mammoth within the next few weeks.  The new system, Swiftly, will provide quick access to accurate real-time transit information and live maps with vehicle locations. In addition, the Swiftly mobile app also contains a real-time trip planner to help users compare the travel time and price of a variety of transportation options, including walking, biking, transit, rideshare, and more.   The Swiftly link at the top of our Home page provides access to route information for buses operating on the Red Line, Purple Line and Town Trolley.  Stay tuned for future announcements about this exciting new transit amenity.
