Explore Eaton Canyon

Within a metropolitan area of over 10 million residents and adjacent to a national forest, Eaton Canyon remains a remarkably diverse ecosystem. Over 1,000 species are verified residents of the canyon, and this number continues to grow as researchers and citizen scientists document others.

The public’s strong desire to recreate outdoors recently put this treasured resource in danger of being loved to death. Thankfully, the thousands of daily visitors and the canyon’s natural environment have resumed a cautious equilibrium.
