As visitors to Devils Postpile, it is partially up to you to protect and preserve this place for future generations. Part of preserving and protecting Devils Postpile is observing park regulations and safety information. This will help you and other visitors enjoy a safe visit to the monument.

Keep Wildlife Wild

Respecting animals at a distance will help create a safer environment in which to view wildlife in their natural habitats.

• Keep your distance from animals, even if they approach you
• Fleas on rodents carry plague. Deer mice feces can carry hantavirus. Do not touch or feed ANY wildlife.
• Dispose of trash in animal-proof trash cans or dumpsters
• Keep your food and trash from wildlife by storing it properly, day and night. More information about proper food storage is available.
• Failure to obey regulations may result in a fine of up to $5,000 and/or impoundment of your property.

Hiking Safety

Within Devils Postpile National Monument is a trailhead that leads to hundreds of miles of High Sierra wilderness trails. Please keep the following in mind when hiking in the area:

• Plan your trip ahead of time. A downloadable map of the monument is available.
• Be prepared for changing weather. Temperatures in the Summer and Fall can easily go from 90 degrees to 50 degrees in a matter of hours. Dress in layers.
• Pack plenty of food and water for your trip. The Rainbow Falls Trail is particularly hot and dusty in the summer.
• All water obtained from lakes and rivers in the area must be fitered or boiled.
• Carry the basic essentials with you, including warm clothes, extra food and water, and a map.
• Read and obey all signs and regulations. They are there for your safety.
• Backcountry permits are required for overnight stays in the Ansel Adams Wilderness. These can be obtained at the Devils Postpile Ranger Station or at any Inyo National Forest Ranger Station in the area. For more information on permits, visit the Inyo National Forest Website.

Swimming

There are a number of great swimming opportunities in the monument, but some are better than others. Keep in mind the folling suggestions when thinking about a swim:

• Always supervise children closely.
• Choose swimming areas carefully and swim only during low water conditions.
• Avoid areas of “whitewater” where streams flow over rocky obstructions.
• Never swim or wade upstream from the brink of a waterfall, even if the water appears shallow and calm. Each year unsuspecting visitors are swept over waterfalls to their deaths when swimming in these areas.
• Never swim or wade underneath a waterfall. Dangerous currents can pull even the best swimmer underwater and cause them to drown.

Fishing

• Fishing in Devils Postpile is regulated under State law.
•  A valid California sport fishing license is required for those persons age 16 years and older.
• When fishing the license must be plainly visible by attaching to an outer layer of clothing above the waistline.
