10 John Muir Quotes That'll Inspire You to Explore America’s Great Outdoors

Office of the Secretary

A leaf, a flower, a stone - the simple beauty of nature filled John Muir with joy.

Born April 21, 1838, Muir has become America's most famous naturalist and conservationist. He shared his love of the outdoors through writing and inspired people to protect our country's wild places like Yosemite, Grand Canyon and Sequoia & King’s Canyon national parks -- earning him the nickname the Father of the National Parks. His passion for these special places fueled the formation of the National Park Service, which will celebrate its 100th anniversary this year.

Muir’s words still inspire countless visitors to experience America’s great outdoors, and now’s the perfect time to get outside and start exploring your public lands. Visit all national parks for free during National Park Week from April 16-24. Get inspired with a few of our favorite John Muir quotes:
