Welcome to our Road Condition Page
When Traveling to Mammoth Lakes please carry chains and a winter survival kit with extra water in your trunk as well. Mammoth Lakes can get multiple feet of snow anytime from late September – May.
Chain Requirements:
R1: Chains are required – snow tread tires allowed.
R2: Chains are required on all vehicles except four-wheel-drive vehicles with snow tires on all four wheels.
R3: Chains are required – all vehicles – no exceptions.
R1 and R2 are the most common conditions. Highway 395 is usually closed before an R3 condition is imposed. Driving on any road during R3 is not wise!
