When traveling in Mammoth Lakes, public transportation is the safest option.  For bus service, the Inyo Mono Transit system that traverses both the Inyo and Mono counties operates door-to-door in Mammoth and nearby communities.  The Yosemite Area Regional Transportation System also offers vacationers bus service around the Mammoth area.

If you want to drive a car but do not want to bring your own, you have three choices: Enterprise Rent-A-Car, Mammoth Car Rental, and U-Save Auto Rental.

Since it tends to snow, a lot, be very careful when driving in Mammoth.  Although the town has a superb snow removal system, there is next to no permitted parking from November 1 to May 1, about half the year.  Winter drivers must carry chains when required, drive slowly, and allow themselves plenty of time to get to where they want to go.  Speeding on icy roads is a frequent cause of accidents every year in Mammoth, so be smart and be slow.

Last but not least, prepare for storms.  Have tools, food, and plenty of gas in case you get snowed in or conditions become invisible.  Mammoth police and transportation services do their best to clear hazardous road conditions, but individual commuter battles against nature should be expected when scuttling around the resort town.
