Muir Woods National Monument - General Park Information

"This is the best tree-lovers monument that could possibly be found in all the forests of the world," declared conservationist John Muir when describing the majestic coast redwoods of Muir Woods. On January 9, 1908, with just the stroke of a pen, President Theodore Roosevelt used the powers of the Antiquities Act to create Muir Woods National Monument. William Kent, who donated the land for the monument, requested that it be named for noted conservationist John Muir.
