Public Transportation


Devils Postpile has recently begun its official push to become a Climate Friendly Park. What does that mean? Devils Postpile is looking to reduce its over all greenhouse gas emissions significantly over the next five years through a variety of actions from carpooling and using public transit to replacing lighting systems and appliances to meet lower energy usage requirements.

But the monument can not do it alone. A large amount of the greenhouse gases produced at the park come from park employees and park visitors and we all have to do our part. The easiest place to start during your visit to Devils Postpile and the surrounding Mammoth Lakes area is to use public transit whenever possible.

In partnership with the Inyo National Forest and the Eastern Sierra Transit Authority, Devils Postpile encourages all of our visitors to take advantage of the extensive public transit available in the Eastern Sierra. This information is also very valuable for visitors planning through hikes on the John Muir and Pacific Crest trails or wishing to do other hikes that involve multiple trailheads.
