As America’s most famous naturalist and conservationist, John Muir fought to protect the wild places he loved, places we can still visit today. Muir’s writings convinced the U.S. government to protect Yosemite, the giant Sequoia, the Grand Canyon and Mt. Rainier as national parks. The John Muir National Historic Site is located in the Alhambra Valley, just 7 miles northwest of Pleasant Hill. The historic home of the United States’ most influential preservationist and naturalist is free and open seven days a week from 10 am to 5pm.
