Traffic & Travel Tips

TRAVEL TIPS

The good news is that there is very little traffic with which to contend in the Eastern Sierra. The only trouble with traveling to Devils Postpile is choosing the time of year wisely. Visitors wishing to see the monument in early June or any time in October should plan on the possibility of snow at any time. Calling ahead is a good idea, as the road to the monument often closes during snowstorms in the spring and fall. The monument is typically closed from October 31-early June depending on the snow.

June promises fewer visitors and amazing waterfall viewing and October brings cooler days and empty trails perfect for viewing the fall colors. If planning a trip during these times, please contact the monument prior to arrival to ensure that the monument is open. Call (760) 934-2289 during the summer months and (760) 924-5500 from October-May for more information.

Visitors to the Mammoth Lakes area in the winter months, please note that the monument will be closed. Heavy snow often makes travel difficult in the town and to the ski area. It is a good idea to carry chains if visiting Mammoth Lakes in the winter.

Did You Know?

The "posts" of Devils Postpile are about 60 feet tall.

The Devils Postpile that you see today is only a fraction of the size the original lava flow formation that filled this valley. Natural processes, especially glaciers, have eroded the rest.
