Driving to Mammoth Lakes After an Unreal Winter

Get updates on changes to Mammoth Lakes local and regional transportation operations.

Following the most historic winter on record at Mammoth Mountain, summer fun in the Eastern Sierra will have some limitations this year, including access to the region via some of our high sierra mountain passes. Many local and regional transportation routes are still in operation but others are still awaiting the Big Melt.

Getting East to West

Due to record snowfall this winter, Tioga Pass will be closed longer than usual this year. Road crews are working hard on clearing mountain roads, but there is still a large amount of snow at higher elevations. Below is a map with alternative options to get across the Sierra.

Both Sonora Pass (Highway 108) and Monitor Pass (Highway 89) are open. Be sure to check road conditions with Caltrans before traveling by calling 1-800-427-7623 or visiting dot.ca.gov. You can also download the Caltrans QuickMap app for use throughout California.

Getting Around Mammoth Lakes

Eastern Sierra Transit Authority (ESTA)

Once you get to Mammoth Lakes, most of our roads are open but there are a few late "bloomers" to be aware of. All ESTA routes in the Town of Mammoth Lakes are currently in operation. Visit the ESTA website for more information on routes and schedules.

Regional Transportation

Yosemite Area Regional Transport System (YARTS)

The road from Mammoth Lakes to Yosemite National Park (Hwy 120/Tioga Pass) remains closed due to record snowfall. YARTS service will resume once the road opens.
