Enos Mills is best known for being the "Father of Rocky Mountain National Park", after his six year struggle to educate the public and Congress of the importance of setting aside large land areas for preservation of scenery and the wild life inhabitants. He was also an author, photographer, nature guide, innkeeper, lecturer, and adventurer. The Enos Mills Cabin is an unconventional Museum that was placed on the National Register of Historic Places on July 3, 1973. Enos' son-in-law and daughter transformed the homestead cabin Enos built in 1885 into an informal dedication to Enos' many achievements that have impacted millions of people around the world.  The Enos Mills Cabin Museum and Gallery is owned and operated by two of Enos' descendants, Elizabeth and Eryn Mills, as a labor of love and gratitude for the better world we now benefit from, because of Enos' selfless efforts for future generations.
